The best camping gear for Colorado is built for altitude: a warm sleeping bag for cold nights, a tent that stands up to wind and afternoon storms, and rain gear you actually carry. Even in July, a campsite at 10,000 feet can drop near freezing overnight and get hit by lightning in the afternoon. This guide covers Colorado’s camping regions, the weather by season, the hazards that catch visitors off guard, and what to pack.
Colorado’s camping regions and climate by season
The Front Range and high Rockies
This is where most people camp: Rocky Mountain National Park, the mountains west of Denver and Boulder, and high country around Leadville, Breckenridge, and Buena Vista. Campgrounds sit anywhere from about 7,000 to over 10,000 feet. The main season runs from late May or June into September. Snow can linger at higher campgrounds into June, and the first snows can arrive in September.
The San Juan Mountains and southwest
The San Juans around Ouray, Silverton, Telluride, and Durango are rugged, high, and remote. Summer brings the North American monsoon, usually from about July into early September, which means frequent afternoon thunderstorms. Mesa Verde National Park sits lower and drier and has a longer season.
The Western Slope and canyon country
Around Grand Junction, Fruita, and the Colorado National Monument, the landscape turns to high desert. Spring and fall are the best seasons here. Summer is hot, and winter nights are cold.
The San Luis Valley
Great Sand Dunes National Park and Preserve sits in a high, dry valley around 8,000 feet. Summer days are warm, the sand surface gets very hot in the afternoon, and wind is common. Nights cool off quickly.
The Eastern Plains
Colorado’s plains get hot summers, strong winds, and severe thunderstorms with hail. Camping here centers on reservoir state parks.
Gear that matters in Colorado and why
Sleep system for cold nights
Temperature swings are the defining feature of Colorado camping. A 40 degree difference between afternoon and pre dawn is normal in the mountains. A sleeping bag rated around 20 degrees Fahrenheit is a practical choice for summer high country camping, and an insulated pad matters just as much as the bag. A mummy shape holds heat better than a rectangular bag on cold nights; mummy bags vs envelope bags explains why. Find both in our sleeping gear section.
A tent built for wind and storms
A three season tent with a full coverage rainfly, strong poles, and solid guy lines handles Colorado summers well. Pitch it tight and stake it fully before you leave camp, since afternoon storms bring gusty wind and sometimes hail. Pick a site away from dead trees, which the state has plenty of after years of beetle kill. Falling limbs and trees are a real hazard in windy weather.
Layers and rain gear
Pack a waterproof rain jacket, an insulating layer like a fleece or puffy, a warm hat, and gloves, even for a July trip. Cotton stays wet and cold, so choose wool or synthetic layers.
Sun protection and water
UV exposure increases with elevation, and it’s easy to burn at 10,000 feet on a cool day. Bring sunscreen, a hat, sunglasses, and lip balm with SPF. Drink more water than you think you need, since the dry air and altitude dehydrate you faster. Treat all backcountry water, even from clear mountain streams, because giardia and other pathogens are present.
Power for longer trips
If you camp for several days and need to charge a phone for navigation, strong mountain sun makes solar practical, but tall trees and afternoon clouds can limit it. Solar panels vs portable power banks can help you decide.
Colorado hazards to plan for
- Lightning: Summer storms often build by early afternoon. Plan hikes to be off peaks and ridges by then. If you hear thunder, head down and away from exposed terrain, open meadows, and lone trees.
- Altitude sickness: Headache, nausea, fatigue, and poor sleep are common if you arrive from low elevation and camp high the first night. Spend a night at a moderate elevation first if you can, drink water, and go easy on alcohol. If symptoms worsen, descend.
- Hypothermia: Wet clothing plus wind plus cold nights can cause hypothermia in summer. Keep a dry layer in your pack.
- Bears and wildlife: Colorado has black bears, and some areas require bear resistant food storage. Moose are common in parts of the state and can be aggressive, especially cows with calves. Give all wildlife plenty of space.
- Flash floods: Canyons and dry washes can flood fast during monsoon storms, even if it isn’t raining where you are. Don’t camp in drainages.
- Wildfire: Fire restrictions are common during dry periods. Check current rules with the managing agency and county before you go.
- Carbon monoxide: Cold nights tempt people to warm the tent with a stove or heater. Never run fuel stoves or heaters inside a closed tent.
Where people camp in Colorado
National parks: Rocky Mountain, Great Sand Dunes, Mesa Verde, and Black Canyon of the Gunnison all have campgrounds. Rocky Mountain’s campgrounds and timed entry system change from year to year, so check the NPS website for current reservation rules.
National forests: Colorado has millions of acres of national forest, including White River, Arapaho and Roosevelt, Pike and San Isabel, San Juan, Gunnison, Rio Grande, and Routt. Developed campgrounds fill quickly on summer weekends, and dispersed camping is allowed in many areas. See our guide to dispersed camping in the USA for how it works.
State parks: Colorado’s state parks include mountain lakes, reservoirs, and plains parks. You’ll need a vehicle pass as well as a camping reservation; check Colorado Parks and Wildlife for current rules.
BLM land: The Western Slope and San Luis Valley have large BLM areas with established campgrounds and dispersed sites, often near popular mountain biking and canyon areas.

Leave No Trace in Colorado
Alpine tundra is fragile and recovers slowly, so stay on trails and camp on durable surfaces like established sites, rock, or dry grass. Camp at least 200 feet from lakes and streams. Pack out everything, including food scraps and toilet paper where required. When fires are allowed, use existing rings, keep them small, and put them out completely; our beginner’s guide to starting a campfire covers safe fire habits. When restrictions are in place, cook on a stove instead.
FAQ
How cold does it get camping in Colorado in summer?
At high elevations, summer nights often drop into the 30s and 40s, and freezing temperatures are possible. Lower campgrounds are milder. Always check the forecast for your specific elevation.
When is the best time to camp in Colorado?
For mountain camping, late June through mid September is the most reliable window. The Western Slope and lower areas are best in spring and fall.
How do I avoid altitude sickness while camping?
Gain elevation gradually, spend a night at a moderate elevation first, stay hydrated, and limit alcohol. If symptoms get worse, descend.
Can I camp for free in Colorado?
Dispersed camping is allowed in many national forest and BLM areas, usually with stay limits. Rules vary by area, so check with the local ranger district or field office.
Shop the gear
A warm bag and a good pad matter most in Colorado, so get those right first. Then add maps and a compass from navigation and an emergency kit from safety and survival for remote high country trips.
