Wondering if Denver is in the mountains? Keep reading for more information about the landscape and geographical features of the Front Range!

I grew up just outside of Denver in Lakewood, Colorado, where we always knew our cardinal directions because the mountains were to the west. During the summer, we’d venture into the Rocky Mountains for camping trips and adventures to hot springs or a drive up Mount Evans (that my mom only attempted once). 

It wasn’t until college that I realized how special it was to grow up in Colorado. I used to ride horses while looking out at Table Mesa in Golden, go on drives through the Rocky Mountains, and soak in natural hot springs – all things you can’t do in, say, Massachusetts. As an avid traveler, I always find myself looking for the drama of the Rockies everywhere I go. 

From the French Alps to the volcano-studded islands of the Azores to the towering cliffs of the Valley of the Condores in Bolivia, I’m always looking for jagged landscapes to admire. If you’re considering visiting or moving to Colorado, you probably already know that you’ll be near the Rocky Mountains – but keep reading for more information about my home state’s geography and climate.

So, is Denver in the Mountains?

No, Denver is not in the mountains – but it’s also not far, especially as US cities go. Denver is set in an area called the Front Range, which is overlooked by the foothills. The foothills are the smaller mountains that lead up to the Rocky Mountains, but they still have some pretty impressive peaks in their own right. 

Because Denver isn’t actually in the Rockies but is instead relatively flat, you get incredible mountain views to the west from Denver and its surrounding cities and suburbs. It also makes for some incredible, cotton candy-pink sunsets. 

Despite being relatively flat, Denver is still at a fairly high elevation – about a mile from sea level. There’s a stair on the Capitol Building that marks where the elevation is exactly 5,280 feet. 

A popular Denver magazine is accordingly titled 5280 and covers lifestyle in the Mile High City. Growing up, I memorized the number of feet in a mile after seeing “5280” magazine prints at the grocery store checkout line. 

Can You Hike in Denver?

No, it’s not possible to hike within the city of Denver because the Front Range is too flat. You can walk in the parks and open space in and around the city, but actual hiking is reserved for the nearby mountains. 

If you’re visiting or moving to Denver to hike and enjoy time in the mountains, I strongly recommend that you get a car. The public transit in Denver is already lacking, but it’s almost impossible to actually reach most of the state’s trailheads without being able to drive.  

The Colorado Rocky Mountains

The Rocky Mountains are some of the most dramatic and beautiful mountains in the world, characterized by large granite peaks that tend to be dusted with snow most of the year. This mountain range formed during the Laramide orogeny period, about 55 million to 80 million years ago.  

The highest peak in the Rockies is Mount Elbert in Colorado, which stretches up to 14,440 feet (4,401 meters) above sea level. By comparison, the highest peak in the Canadian Rockies is Mount Robson, with an impressive elevation of 12,972 feet (3,954 meters). 

Tourists and locals alike flock to the Rockies for some of the best skiing and snowboarding in the country. You can also hike, soak in hot springs, camp, and backpack/mountaineer, all within a few hours of Denver. During the fall, one of the best things to do is drive around the mountains to see the aspens after they turn brilliant shades of gold and reds. 

Landscapes You’ll Find in Colorado

Colorado is a large state – about four times the size of Ireland (and, yes, that’s one of my favorite fun facts!). Within this large state, there are several climate types and landscapes, with most of the variation taking place from east to west. To the east are the Eastern Plains, followed by the Front Range and foothills, then the Rocky Mountains, and finally the Western Slope. 

Most of Colorado’s urban areas are in the Front Range, right where the plains meet the foothills. 

Eastern Plains

Colorado’s Eastern Plains are actually the westernmost part of the Great Plains, which stretch from Colorado up to southern Canada, down to Texas, and all of the way to Oklahoma. The Eastern Plains have a semi-arid climate, meaning that they receive little rainfall. They’re also the flattest part of Colorado, consisting mostly of rolling hills. 

The Eastern Plains of Colorado were previously home to a number of Native Americans, including the people of the Arapahoe, Cheyenne, Kiowa, Pawnee, Sioux, and Ute tribes. 

Today, most of the Eastern Plains are farmlands or ranchlands. This region of Colorado is sparsely populated and tends to be very politically conservative. Although Colorado doesn’t see as many tornadoes as other parts of the country, when they do strike it’s most often in the Eastern Plains. 

If you want to experience some of Colorado’s (alive and well) western heritage, visit the National Western Stock Show. This huge event takes place every January for just over two weeks and features horse shows, rodeos, livestock demonstrations, and plenty of kid-friendly events. 

Front Range

Compared to the Great Plains, the Front Range is a relatively small area that stretches from Casper, Wyoming to Pueblo, Colorado just to the west of the Rockies. The Front Range sees slightly milder temperatures than the Eastern Plains, with the Rockies providing a little bit of protection from the storm systems that create tornadoes in the plains. 

The cities of Denver, Boulder, Fort Collins, and Colorado Springs are all considered part of Colorado’s Front Range. These urban areas are home to the majority of the state’s population and tend to be much more politically liberal than other parts of the state. The major highway that runs along the Front Range is I-25, and the areas surrounding the interstate are known as the I-25 Corridor. 

The temperatures in both the Eastern Plains and the Front Range tend to be warmer than the Rockies because they’re at lower elevations. So, on a hot summer day in Denver, you might need a down jacket if you travel all of the way up to Breckenridge (especially after dark). 

Colorado Rocky Mountains

The Rocky Mountains technically start as foothills just a little ways west of Denver. These hills are defined as the transition zone between the plains of Denver and the peaks of the Rocky Mountains. 

The central crest of the Rocky Mountains is the Continental Divide, the highest portion of the mountain range. This crest also determines whether water will flow east or west, depending on which side of the divide it falls on. 

Many indigenous peoples lived in the Rocky Mountains, with evidence of human activity in the area that dates back to 10,000 and 8,000 BCE. Those peoples include the members of the Blackfoot, Crow, and Cheyenne tribes. 

Today, tourists and locals alike flock to the Rocky Mountains to ski, hike, camp, backpack, mountaineer, and search for displays of fall foliage. Rocky Mountain National Park alone receives about 4.5 million visitors each year. Although I usually skip RMNP in the summer to avoid the crowds, snowshoeing in the park is one of my favorite winter activities in Boulder. 

Western Slope

An often overlooked part of Colorado’s geography is the Western Slope, which technically starts on the western side of the Continental Divide. The Western Slope is more filled with canyons and sandstone than other parts of Colorado, making for some incredible sights and rock formations. 

One of my favorite areas on the Western Slope is Glenwood Springs, a small mountain town with a large hot spring pool of the same name. The hills surrounding this little enclave are dotted with trees and shrubs that, along with the reddish brown hills, create an interesting texture that’s unlike anything I’ve seen elsewhere in the world. 

Colorado’s Climate

Colorado has a complex climate, impacted largely by the Rocky Mountains. By complex, I mean that the best way to predict the temperature and weather patterns is by elevation, not distance from north to south. In Colorado, the climates range from semi-arid to alpine. 

Sunshine is common throughout the year, and nights are generally cold and clear. It’s very common to have nights that are chilly enough for coats and gloves, then by midday the weather is warm enough for shorts and a tee shirt. 

March is the snowiest month in Colorado. Unfortunately, the warmer temperatures mean that this snow is usually very wet and heavy. It’s common for the heavy, wet spring snow to take down trees and power lines at least once per year. Locals know to shake the snow from their tree limbs as soon as possible to prevent breakage. 

Anecdotally, Colorado really only has two seasons: summer and winter. Although there are a few weeks of spring and fall each year, the weather mostly just transitions from hot to cold. I had never really noticed the lack of a “true” spring or fall until I moved to Massachusetts for college, where the four seasons are very distinct from each other. 

The Weather Changes Quickly

One thing you’ll learn quickly after spending some time in Denver is that the weather changes very quickly. When I was in elementary school, there would often be days with such intense snowstorms in the morning that school was canceled for the day, only for us to be playing outside in t-shirts in the afternoon. 

During the summer, Colorado is prone to afternoon storms that can roll in with little notice. In Denver, these storms cause the occasional tornado or funnel cloud, but more often they’re accompanied by lightning. It’s common to see kids waiting on the side of a pool in Denver in the afternoon after a lifeguard spots lightning or hears thunder in the distance. 

My Favorite Hiking Trails Near Denver

In offices around Denver and Boulder, it’s very common for Monday morning meetings to start with a recap of the weekend’s hiking or skiing adventures. Whether you enjoy gentle trails or more serious adventures like climbing a 14,000 ft peak (known locally as “bagging peaks”), the foothills and the Rockies have plenty of options. 

Here are some of my favorite hiking trails near Denver. Most of these trails are pretty short, but sometimes you don’t want to spend your whole Saturday on the mountain. I find that 3 to 5 miles is a great length for a hike that feels substantial without tiring me out. 

Royal Arch

One of the most popular hikes in the Denver Metro Area has to be Royal Arch Trail, a steep trail that leads to an incredible lookout point over the City of Boulder. As the name suggests, the lookout point for the trail also contains a natural arch, similar to (but smaller than!) the arches you’ll find in the desert in Utah. 

Don’t be deceived by the trail’s relatively short length of 3.3 miles, it’s definitely a climb. If you attempt this trail with a dog, be sure that you can either carry them or they’re agile enough to do a little bit of scrambling. Sturdy shoes are essential, especially if there has been any recent rain or if ice is present on the trail. 

Still, the views are great and this is a must-do hike in the Denver/Boulder area if you’re up for a more intense trail. 

Rattlesnake Gulch

This lesser-known trail is one of my favorites, located just south of central Boulder in Eldorado Canyon State Park. It’s far gentler than the steep climb of Royal Arch, making it perfect for families or newer hikers. For such a short hike, the views are fabulous – made even better by the chance of seeing rock climbers making their way up the granite faces.

Unlike most of the trails in Boulder, there is a fee to enter Eldorado Canyon State Park. Park officials have implemented a timed entry system during weekends and holidays from May 15 to September 15. You can register online for an entry time by visiting the Colorado State Park website. As of this writing, the fee per vehicle is $10. 

On weekdays or in the off season, I would still recommend that you visit as early as possible so that you have the best chance of getting in. The park tends to be very busy between 9am and 3pm.  

Hanging Lake

Calling Hanging Lake a trail “near Denver” is a bit of a stretch, but it’s so popular that I thought it needed to be included. This hike is very popular among people who are also visiting Glenwood Springs, a popular natural hot spring pool in the western portion of the Rockies. 

The hike itself is rather challenging, so it could be hard to complete with children or those who have limited mobility. Still, it ends with an incredible lake view that will absolutely feel worth the effort. 

Note that you will need to buy a permit and choose a reservation time before you go. As of this writing, the permit costs $12 per person during the summer and $10 per person during the winter. The cost of the permit includes parking. 

Walker Ranch Loop

The Walk Ranch Loop is actually my favorite hike in Colorado and I used to do it whenever I could convince someone to go with me. The trail is about 7 miles long and mostly flat, with a few mountain views and great views of a rushing stream (there’s a bridge for the actual crossing). There is one steep section of the hike with rock stairs about halfway around the loop. 

If you only have time for one hike in Colorado, you might opt for a trail with more epic views – the Walker Ranch Loop definitely has a more local feel. 

I prefer to do the loop clockwise so that the uphill climb is mostly contained to the stairs near the creek. (This is also my preference when hiking around Lake Glendalough in Ireland, if you were wondering! I love getting the steepest parts out of the way as quickly as possible.)

Safety Tips for Hiking in Colorado

As you might expect, hiking is very popular in Colorado and is enjoyed by locals and visitors alike. While most people don’t have any issues while hiking in Colorado, there are some safety tips that you should follow when exploring the Rocky Mountains. 

Stay on the Trail

In Colorado, we’re lucky to have lots of well marked and easy to follow trails through the Rocky Mountains. In order to leave no trace and keep from getting lost, you should always stay on the trails when hiking in the Rockies. Staying on the trail also helps to prevent erosion. 

Use a Map for Longer Hikes (And Know How to Use It)

Getting lost while hiking the Rockies can be deadly, so it’s important that you take care to navigate while you’re out on the trails. Smaller trails in state parks are probably very well marked and easy to follow, but longer hikes require more gear and specialized knowledge. At the very least, I recommend that you download and use a navigation app like All Trails. 

Carry a physical map and learn the basics of navigation before heading out into the backcountry. REI offers navigation courses that cover the very basics of using a map and compass. It can be harder than it sounds to orient yourself without a smartphone, so it’s worth spending a little time learning how to use these tools well before you ever need them. 

Tell Someone Where You’re Going and When You’ll Be Back

A simple and effective way to ensure that someone will know if or when you get lost in the mountains is to tell them before you go. Shoot a quick text to a friend or loved one telling them where you’re going, which trail you’ll take, and when (approximately) you anticipate that you will return. 

I like to also share my location on WhatsApp or using iMessage, but this will definitely drain your battery quickly if you’re not careful. 

Carry a Portable Charger

A portable charger is one of my favorite travel accessories, and I use them when hiking, traveling in Europe, or just when I’m out and about in the city. In case your phone battery dies unexpectedly, a portable charger can save the day. 

I love the CFIAI Portable Charger Power Bank because it is relatively lightweight, has a lightning cord and USB-C cord built in, and holds about two full charges. It’s also the fastest portable charger I’ve ever used. 

Stay Below Treeline After 12pm

There’s a reason you always see serious hikers leaving around 3am when they hike in Colorado: you never want to be above treeline in the afternoon or anytime you see clouds moving in. Afternoon thunderstorms can roll in with little warning, creating dangerous lightning conditions for hikers. 

The problem is compounded above the treeline, where a hiker can be the tallest thing around and therefore be more vulnerable to a strike. So, be sure that you’re off the summit and below treeline by about 12pm. 

Lock Your Car 

Trailheads are notorious for being targets for thieves, so it’s important to lock your car and hide your valuables before you leave for your hike. I wouldn’t leave your keys on the tire or in another obvious place, as thieves will probably think to check these spots. 

Be Aware of Your Surroundings

Denver is not a particularly safe city, as US cities go. Given the proximity of the mountains to Denver, it’s a good idea to be aware of your surroundings whenever you’re hiking or spending time outside. Look for strange behavior, cars, or other signs that something might not be quite right. 

Know What to Do If You See Wildlife

Colorado has several species of wildlife that can be dangerous if encountered while in the mountains. From venomous rattlesnakes and black widow spiders to large predators like mountain lions and bears, there are some real hazards in the Rocky Mountains. 

Here’s a brief overview of what you should do if you see the following wildlife in Colorado. I recommend that you also read the resources linked below before you head into the woods and, of course, heed any posted warnings.

✅ Black Bears: Keep your distance if you spot one and help it identify you by speaking firmly and waiving your arms. Never run away (you don’t want to trigger its chase response), and instead back away slowly while making yourself look large. Be especially careful if you see a bear with cubs. Fight back if attacked. 

✅ Mountain Lions: Never approach a mountain lion. If you stumble upon one, speak to it loudly and firmly to show that you’re not its regular prey, back away slowly (never run), and make yourself as large as possible using jackets or clothing. Fight back if attacked. 

✅ Rattlesnakes: Remain calm and give the snake plenty of space to escape. Do not attempt to kill or throw things at the snake, instead back away slowly. If you hear a rattle, take a moment to locate where the sound is coming from so that you don’t accidentally step on it. 

✅ Moose: Never approach a moose and give the animals as much space as possible if you encounter one. Stay calm and never run away from a moose, instead back away slowly. If a moose starts to act aggressively, hide behind a tree or other solid object or inside of a vehicle or building. Should you get knocked down, cover your head and neck while curling into a ball. 

✅ Black Widow Spiders: In the very rare event that you encounter a black widow spider while in the mountains or urban areas of Colorado, stay back and do not attempt to touch it with your bare hands. Urgently seek medical attention if bitten.  

FAQs: Is Denver in the Mountains?

Curious about Denver’s geography and still have questions? Here are the answers to some of the most popular queries from travelers. 

How close is Denver to the mountains?

Denver is very close to the mountains, as major US cities go, but it’s not actually in the mountains. You can reach the peaks of the foothills by driving along I-70 for about 30 minutes or so. There are also hikes that you can do from near the center of Boulder, which is only a 35 minute drive from downtown Denver. 

What is the closest mountain town to Denver?

The closest true mountain town to Denver is Idaho Springs. This charming little town is the first real stop along I-70 as you drive into the Rocky Mountains. As the name suggests, it is home to the closest natural hot springs to Boulder/Denver: Indian Hot Springs. Downtown Idaho Springs also has some restaurants and shops – it’s worth a stop if you’re taking a leisurely drive along I-70.

What city in Colorado has mountains?

There aren’t any Colorado cities that have their own mountains, but Colorado Springs and Boulder are both situated very near to the foothills. Within the Rocky Mountains, the large towns of Aspen, Breckenridge, and Vail, among others, attract skiers and vacationers every year. 

Is Denver hilly or flat?

Although there are some hills, Denver is mostly flat because it is set on an ancient seabed. As the name suggests, Capitol Hill is one of the largest hills in Denver. There are also some hills in the Highlands, an area to the northwest of downtown Denver. Overall, though, most of the state’s steep climbs are on hiking trails in the mountains. 

Conclusion: Is Denver in the Mountains?

So, as you’ve likely gathered by now, Denver is not actually located in the Rocky Mountains. Instead, the Mile High City is set just below the foothills, which lead up to the Rockies. Because the city isn’t actually in the mountains, we can enjoy incredible views of the foothills from around Denver – and the associated sunsets!

When you want to get into the mountains to hike or explore, you only need to drive about 30 to 45 minutes. There are a number of fabulous trails less than an hour from downtown Denver. For bigger, longer hikes like 14,000 ft peaks, expect to drive at least an hour from downtown Denver in most cases.
