Do you need a permit to ride an ATV in Colorado?

Yes — Colorado requires an OHV registration sticker ($25.25/year) for ATVs and UTVs riding on designated OHV trails on National Forest and BLM land. The sticker is available from CDPHE or authorized dealers. Street-legal vehicles on maintained forest roads do not need the OHV sticker. All riders under 18 must wear helmets.

When can you ride ATVs on the Alpine Loop in Colorado?

The Alpine Loop (Engineer Pass and Cinnamon Pass) is typically accessible from late June through early October, weather dependent. Snow can close the high passes through June in heavy snow years and can return as early as September. Check local Ouray and Lake City outfitter websites or social media for current road conditions before your trip.

Can you ride ATVs on Moab trails from Colorado?

Moab, Utah is about 2 hours from Grand Junction, CO and is one of the best OHV destinations in the West. Colorado OHV registration stickers are not valid in Utah — Utah requires its own registration. However, many Colorado riders make the Moab trip for iconic trails like Hell's Revenge and the Fins and Things area.

Q: What is the easiest ATV trail near Denver?

Rampart Range Road is the easiest major ATV area near Denver — just 45 minutes away via US-85. The system includes mostly packed dirt roads suitable for beginner riders and all ATV/UTV sizes. Grand Mesa (2.5 hours from Denver) also has extensive beginner trails on the flat plateau top.

Q: What size UTV can ride the Alpine Loop?

Side-by-sides (UTVs) up to 60 inches wide can typically navigate the Alpine Loop, though some tight sections and shelf roads are more comfortable in narrower vehicles. Standard 50-inch UTVs navigate the route easily. Wider UTVs (64+ inches) can complete the route but require extra caution on narrow shelf road sections. The route is not suitable for full-size trucks without a high-clearance 4WD setup.

Colorado's best ATV and OHV trails span alpine passes, canyon country, and national forests. Here are the top off-road riding destinations in Colorado for ATVs, UTVs, and dirt bikes.

Best ATV Trails in Colorado (2026) — Off-Road Paradise

Colorado is one of the premier ATV and off-road riding destinations in the United States. The state's combination of high-altitude mountain passes, vast National Forest land, and Bureau of Land Management terrain creates hundreds of miles of legal OHV trail network. From beginner-friendly meadow loops to expert-only high-alpine routes crossing 13,000-foot passes, Colorado has epic off-road riding for every skill level. This guide covers the best ATV trails in Colorado organized by region with difficulty ratings, access info, and riding tips.

Quick Answer: Best ATV Trails in Colorado

Colorado's top ATV trail destinations include Moab (just across the Utah border but the standard reference point for canyon riding), Ouray/Silverton's Alpine Loop (most iconic Colorado high-country ATV route), the Grand Mesa OHV system (largest flat-top mountain in the world), Rampart Range Road system (easy access from Denver/Colorado Springs), and Phantom Canyon Road (Arkansas River canyon, 4x4 Jeep territory).

San Juan Mountains: The Alpine Loop Region

Alpine Loop Backcountry Byway (Ouray / Lake City / Silverton)

The Alpine Loop is arguably the most famous ATV/Jeep route in Colorado, crossing two 12,000+ foot passes through the San Juan Mountains — Engineer Pass (12,800 ft) and Cinnamon Pass (12,620 ft). The 65-mile loop connects Ouray, Lake City, and Silverton through breathtaking high-alpine terrain with views of 14,000-foot peaks in every direction.

Best for: ATVs, UTVs, Jeeps, 4WD vehicles
Season: July through October (snow closes passes through June most years)
Fee: Free (USDA National Forest land, no OHV permit required for street-legal vehicles)
Highlight: American Basin wildflower meadows and views from Engineer Pass summit

Black Bear Pass (Telluride)

One of the most challenging and famous Jeep roads in Colorado, Black Bear Pass descends from 13,000+ feet above Telluride via a series of tight switchbacks carved into sheer cliff faces. Not for the faint of heart — some switchbacks require multiple back-and-forth maneuvers and the consequences of a mistake are severe. One-way traffic only (east to west), and ATVs/UTVs must be registered and meet width requirements. Legal ATV access — but this is an expert-only route.

Grand Mesa & Western Slope

Grand Mesa OHV System (Mesa County)

The Grand Mesa is the largest flat-top mountain in the world — a massive 53-mile-wide plateau rising to 10,000+ feet between Grand Junction and Glenwood Springs. The Grand Mesa National Forest manages an extensive network of OHV trails across the mesa, with beginner loops on the plateau top and more technical routes on the edges.

Total trail miles: 100+ miles of designated OHV trails
Difficulty: Beginner to Advanced (wide variety)
Best for: All ATV and UTV sizes; families with beginner riders
Season: June through October
Fee: Free (National Forest OHV areas, Colorado OHV registration required)
Access: CO-65 (Grand Mesa Scenic Byway) from I-70 Exit 49

Unaweep-Tabeguache Scenic Byway Area

Between Grand Junction and Montrose, the canyon country west of the Grand Mesa features excellent ATV terrain on BLM lands. The Unaweep Canyon area has routes ranging from beginner two-track to rocky technical 4WD. Free access, no OHV sticker required on BLM roads (required on designated OHV trails).

Front Range: Easy Access from Denver & Colorado Springs

Rampart Range Road System (El Paso & Douglas Counties)

The Rampart Range Road is the most accessible major OHV area from Denver and Colorado Springs — just 45 minutes from downtown Denver via US-85 or CO-67 from Colorado Springs. The system includes over 100 miles of roads and trails on Pike National Forest lands ranging from maintained dirt roads to rocky technical singletrack.

Difficulty: Beginner to Intermediate (mostly dirt roads, some technical)
Distance from Denver: 45 minutes
Distance from Colorado Springs: 30 minutes
Season: Year-round (some seasonal closures)
Fee: Colorado OHV registration sticker required for off-highway use ($25.25/year)

Tarryall Creek / Lost Creek Area (Park County)

About an hour southwest of Denver in Park County, the Lost Creek Wilderness boundary area has excellent OHV trails on National Forest and BLM lands. Scenic mountain terrain at 8,000–10,000 feet, less crowded than Rampart Range, with trails suitable for ATVs and side-by-sides. Colorado OHV sticker required.

Southwest Colorado: Canyon Country

Canyons of the Ancients National Monument / Dolores Area

Southwestern Colorado's canyon country around Dolores and Cortez offers excellent ATV riding on BLM lands adjacent to Canyons of the Ancients National Monument. Slickrock terrain, canyon vistas, and red-rock scenery rivaling Moab but with far fewer crowds. Best ridden in spring and fall — summer heat in the canyon country reaches 100°F+.

Gear for Colorado High-Altitude ATV Riding

Colorado's high elevations and mountain weather demand preparation. Afternoon thunderstorms are common above treeline from July through September — always check weather and carry rain gear. A quality rear rack storage bag for your ATV lets you carry layers, a first aid kit, and emergency supplies easily. For rides crossing 12,000+ foot passes, a 2,500–3,000 lb ATV/UTV winch is essential recovery gear on shelf roads and rocky terrain where getting stuck can be dangerous.

Colorado OHV Regulations to Know

OHV registration: All ATVs and UTVs riding on designated National Forest or BLM OHV trails must display a Colorado OHV registration sticker ($25.25/year from CDPHE). Street-legal vehicles on maintained forest roads do not require the sticker.
Helmets: Colorado law requires helmets for ATV operators and passengers under 18. Adults are exempt on private land but helmets are strongly recommended on all public trail systems.
Alpine Loop timing: Engineer and Cinnamon passes are typically snow-free from late June through early October. Check CDOT and local outfitter social media for current conditions before a trip — snow can fall any month at 12,000 feet.
Leave no trace: Colorado's OHV trail system faces ongoing pressure from overuse. Stay on designated trails, pack out all trash, and avoid creating new routes off-trail. Trail erosion and resource damage result in permanent trail closures.
