Camping in Colorado

National forest & BLM campgrounds

Outside the state parks, the U.S. Forest Service and BLM run hundreds of developed campgrounds — often more rustic (vault toilets, no hookups) but in gorgeous spots.

• Reserve most at Recreation.gov (the federal booking site and app). Popular campgrounds fill up fast on summer weekends and holidays, so book early.
• Some campgrounds are first-come, first-served only — no reservations. Arrive early on Friday.
• Many high-country campgrounds open around mid-to-late May and close in September or October with the first snows — but exact dates depend on snow, road repairs, staffing, and fire closures, so check the facility's page.
• You usually don't need a state-park pass for these — you pay the campground fee instead.
• Most developed campgrounds have a volunteer camp host who collects fees on first-come loops, sells firewood and ice, enforces quiet hours, and knows the current conditions and bear activity. Find them when you arrive — on self-pay loops, you fill out an envelope and pay at the post.

Dispersed ("free") camping — read this part carefully

This is Colorado's hidden gem: you can camp for free on most national-forest and BLM land. About a third of Colorado is public land, and much of it is open to dispersed camping. But "free" is not "anything goes," and the exact rules are local — they change by forest, field office, and special order. Here's the common pattern, with one real example:

• Usually no permit needed — except in wilderness areas and some high-traffic spots that now require permits or have numbered sites.
• Use a site that's already been used — look for an existing fire ring and a flat, bare pull-off. Don't make a new site or widen one.
• Camp away from water, and near a designated road. The exact distances are set locally. Example: the White River National Forest tells dispersed campers to stay at least 100 feet from any water and no more than 300 feet from the road centerline. Other forests use different numbers.
• Stay limit: generally 14 days at one spot within about a 28–30 day window, then move on — but how far varies. White River says move outside a 20-mile radius; BLM areas often say roughly 25–30 miles. Some popular spots have shorter, 7-day limits.
• Stay on designated roads to drive and park — use the Motor Vehicle Use Map (MVUM), which shows where dispersed camping is allowed. (Our off-road guide explains how to read an MVUM.)
• Finding a legal spot: download offline maps before you lose signal, and use apps like Avenza (with the MVUM), onX, or FreeRoam to confirm the road and camping are allowed — but a crowdsourced pin is not proof a site is legal. Cross-check the forest's MVUM and dispersed-camping order.
• No facilities means pack it all out — every bit of trash — and bury human waste in a cathole (commonly 6–8 inches deep, at least 200 feet from water, camp, and trails), or pack it out where required.

Bottom line: know the pattern, but look up the specific National Forest or BLM field office for the exact distance-from-water, distance-from-road, and move-along rules before you go.

National parks & timed entry

Colorado has four national parks, each with its own campgrounds and rules: Rocky Mountain, Great Sand Dunes, Mesa Verde, and Black Canyon of the Gunnison. Two things confuse visitors.

1) The entrance fee is separate from everything

A national-park entrance fee or pass (or the federal America the Beautiful pass) is required to get in — it's not the same as the Keep Colorado Wild Pass, and not the same as a camping or timed-entry reservation.

2) Rocky Mountain National Park needs a "timed entry" reservation

From late May through mid-October, RMNP requires a timed-entry reservation to drive in during the busy daytime hours — on top of the entrance fee. The plain version (the 2026 dates are an example; confirm before you go):

• There are two kinds. "Timed Entry + Bear Lake Road" covers the busiest corridor plus the rest of the park (required ~5 a.m.–6 p.m., about May 22–Oct 18, 2026; sells out first). "Timed Entry" covers the rest of the park, excluding Bear Lake Road (required ~9 a.m.–2 p.m., about May 22–Oct 12, 2026; easier to get). Outside those hours you don't need one.
• It's per vehicle, booked in advance on Recreation.gov (about a $2 processing fee). You enter within a 2-hour window, then come and go.
• Campers are usually covered: a camping reservation at a park campground generally includes timed entry to reach your site — but read the current NPS page, since the corridors and timing have conditions.
• You can't buy timed entry at the gate; reserve online.

Camping in the parks

Developed campgrounds (RMNP's reservable sites, Piñon Flats at Great Sand Dunes — open about April 1–Oct 31, Morefield at Mesa Verde) are reserved in advance. Most go through Recreation.gov, but a few (Morefield is one) use a park concessionaire's system instead — check the park page.

Backcountry/wilderness camping needs a permit. RMNP's main season runs roughly May 1–Oct 31, with a wilderness administrative fee and the reservation window opening around March 1 on Recreation.gov — and in RMNP's wilderness, a bear canister is required. At Great Sand Dunes, you can backpack the dunes backcountry of the National Park with a permit reserved on Recreation.gov (a small fee, recently about $6); backpacking in the adjacent National Preserve generally doesn't require a permit — but check, since parking for a Preserve trip can have its own rules.

Bears & wildlife

Colorado has an estimated 17,000–20,000 black bears — and the black bear is the only bear here (despite the name, they can be black, brown, cinnamon, blond, or honey-colored; there are no known grizzlies in Colorado). Bears that learn to eat human food usually end up killed — the hard truth behind "a fed bear is a dead bear." Your food storage protects you and the bear.

Store your food like a bear is coming

• At campgrounds, lock all food, drinks, and toiletries in your car or a bear locker — never in your tent. Cover coolers (bears know what coolers are), and use bear-proof trash cans.
• Food-storage orders are local. Some forests, wilderness areas, and campgrounds have food-storage orders or seasonal hard-sided-camping requirements — and during heavy bear activity, a few campgrounds even ban tents for a season. Check the campground page, forest alerts, and permit conditions.
• Bear canisters are required for overnight wilderness camping in Rocky Mountain National Park (a hard-sided, lockable canister) and throughout the Maroon Bells–Snowmass Wilderness (an IGBC-approved container — including the Four Pass Loop and Conundrum Hot Springs). No container can mean a ticket and being sent home, so check the current permit page for the approved list.

Other wildlife

Don't feed any wildlife — not the chipmunks, not the deer, not the begging jay. And moose are common near water and on trails: they're big, fast, and unafraid, so give them lots of room and never get between a cow and her calf — a moose is arguably the more dangerous animal you'll meet.

Do you need bear spray? It's optional here. Colorado has black bears, not grizzlies, so good food habits matter far more than spray; if you carry it, keep it accessible and know it's a last-resort deterrent, not something you spray on gear. And don't count on a bear box being there — many trailheads and dispersed sites have none, so bring your own hard-sided storage and never leave a cooler or scented items in a tent or open truck bed overnight.

Water, weather & altitude

The stuff that surprises flatlanders — and the high country doesn't forgive much:

• Don't drink untreated water. Even clear mountain streams can carry giardia and other bugs. Filter, boil, or treat all backcountry water.
• Afternoon thunderstorms are the rule in summer. Lightning above tree line is deadly — be off high peaks and ridges by early afternoon, and plan hikes early.
• Never camp in a dry wash or canyon bottom. Colorado's summer monsoon drives flash floods that arrive from a storm miles upstream — the Big Thompson Canyon disaster is the local lesson. Pitch on higher ground away from creeks and arroyos, and watch the weather upstream, not just overhead.
• Altitude is real — especially for sleeping. Drink lots of water, take it easy your first day or two, and watch for headache and nausea. Sleeping at 9,000–11,000 ft hits harder than a day hike, so spend your first night lower (Denver or the foothills) before camping high, and go easy on alcohol that first night.
• Weather flips fast. It can snow any month in the high country. Bring layers, rain gear, and a warm hat even in July — mountain nights get cold, and hypothermia is a danger when you're wet and chilled.
• Seasons & closures: high-country campgrounds and roads are usually open late May/June through September/October — then they close, the water is shut off, and access roads gate or snow in. Confirm the campground's actual open/close dates and the road status before you drive up; lower-elevation and plains camping works much earlier and later.
• Check the road, not just the reservation. A booked site is no good if you can't reach it. Look at CDOT/COtrip for highway and pass closures and chain laws, and the National Forest's alerts and MVUM for gated or seasonally closed forest roads — many access roads need high clearance or 4WD.
• Plan for zero cell service. Coverage vanishes minutes from most trailheads. Leave your itinerary with someone, consider a satellite messenger or your phone's satellite SOS, and look into the cheap CORSAR card (Colorado Outdoor Recreation Search and Rescue) that helps reimburse the county team if you need rescue.
• Small critters, real risks. Plague lives in prairie-dog and rodent fleas, and hantavirus comes from deer-mouse droppings in closed cabins and sheds — so avoid rodent burrows and dusty enclosed structures, don't handle dead animals, and use repellent and check for ticks.

Dogs & pets

• In state parks and most campgrounds, dogs are welcome but must be leashed (no longer than 6 feet) and never left alone at a site. Pick up and pack out their waste. Some sites and trails restrict pets.
• Big surprise for visitors: national parks mostly ban dogs on trails and in the backcountry. In Rocky Mountain National Park, dogs are not allowed on any trail, tundra, or meadow — only in parking lots, campgrounds, picnic areas, and along roads, on leash. If you're bringing a dog, plan around this.
• National forests and BLM land are usually more dog-friendly (leash or strong voice control, depending on the area and any local order).
• Pet rules vary a lot — check the exact park, campground, or forest page.

Sleeping in your vehicle or RV

• Highway rest areas: you may stop and rest, but they're generally not for overnight camping. Don't set up camp.
• Trailheads and day-use lots: usually no overnight camping — they're for day visitors. Check the signs.
• Dispersed camping (in a vehicle) is fine on national-forest/BLM land where it's allowed — same rules as above.
• Store parking lots (like Walmart): sometimes okay, but it's up to the store and the local town — many Colorado mountain towns ban it. Always ask the store and check local rules.
• RVs: developed campgrounds offer hookups (electric/water/sewer) and dump stations; dispersed sites have nothing, so come self-contained and pack out gray and black water responsibly.
• Check the amenities before you book. Many state-park standard sites have no hookups and no showers, water is shut off in the cold months (vault toilets only), and dispersed sites have nothing at all — so read the site's amenity list, pack in your water or plan to treat it, and know where the nearest dump station and potable fill are.

Waste & camp etiquette

Human waste

• Dig a cathole commonly 6–8 inches deep, at least 200 feet (about 70 steps) from water, trails, and camp. Cover it when done, and pack out your toilet paper in a bag.
• Above tree line or on popular peaks and rivers, the ground can't break waste down — use a "wag bag" (a pack-out kit) and carry it out. Some areas require it.
• Keep soap, food scraps, and waste at least 200 feet from any stream or lake — they all harm the water.

Campground etiquette

• Quiet hours are typically 10 p.m. to 6 a.m. — keep voices and music down.
• Generators usually have limited hours, and many tent loops ban them.
• Pay promptly at self-pay areas, and don't hold sites with gear you're not using.
• Wilderness areas often have small group-size limits (commonly around 12 people) to protect the land.
