18 Road MTB Trails: An Introduction
If you’re a mountain biker on Colorado’s Western Slope and haven’t spent time on the 18 Road trails in the North Fruita Desert Recreation Area, you’re missing one of Colorado’s most fun (and approachable) flow trail networks. The system is built for momentum: smooth, punchy singletrack with rollers, berms, table-top jumps and plenty of high-speed ridge runs. It suits riders who want fast and fun laps, but there’s plenty of room for bikers who want longer runs, too. Moreover, it's great for beginners to build their skills and collect their first big grins.

18 Road Mountain Bike Trails: Quick Facts
The 18 Road trail system is north of Fruita, off 18 Road — about a 20-minute drive from Fruita, or roughly 30 minutes from Grand Junction. 18 Road itself is a long dirt road that turns into the recreation area. The BLM manages the area and posts maps and access details.
Day-use parking available: There are several parking lots to the east and west of 18 Road. The trails are accessed directly from 18 Road.
Camping available: There are upper and lower campground loops to the north and south if you want to make a weekend out of it.
Busy Times: Spring through fall are the busiest months; many trails are usually snow-free by March.
Location Tip: If you’re using a maps app to find the trails, look for “North Fruita Desert” or “18 Road Parking.” If you’re mapping to the campgrounds, type in “BLM North Fruita Campground.”
Terrain & Soil: Desert singletrack that rides fast when dry. The local bentonite clay turns tacky and glue-like when wet (seriously: if it’s rained or snowed a lot recently, give it a few days to dry out!). Check trail conditions on local MTB Facebook groups, like Dirt Mermaids or COPMOBA, before you go.
Scenery: 18 Road offers wide, open desert views across the Grand Valley and the Bookcliffs: scrub, juniper pockets, and long sightlines for speed. The ridge runs look and feel like classic western desert singletrack: brown and buff benches, distant mesas, and big skies that are awesome at golden hour. The riding culture is friendly and busy on weekends; you’ll see everything from beginner riders to fast shuttle-style crews.
Trail Features & Difficulty Range: There is truly something for everyone at the 18 Road trail system. Flowy ridge lines, short punchy climbs, fast descents, and progressive optional features — excellent for learning speed control and flow skills.
Popular 18 Road MTB Trails
Here are a few of the trails you can enjoy at the 18 Road trail system. Lengths are approximate! Note that many of the trails in this system interconnect. Riders can build custom loops that string together for a long day of descents and short climbs. Check out the BLM map for a closer look.
Prime Cut
- Length: ~2 miles
-
Difficulty: Easy
-
Why ride it: Prime Cut is a classic 18 Road warm-up ascent, and it’s used to link up to the downhill trails like Kessel Run, PBR, Joe’s Ridge, and Chutes & Ladders. It’s either Prime Cut or the road, and Prime Cut is much more fun. This trail is uphill only!
Kessel Run
-
Length: ~2.1 miles
-
Difficulty: Easy to Intermediate
-
Why ride it: Downhill-focused and fun. It’s a popular run, so there’s some rutted trail, but it has smoother, bermed turns also. Kessel Run is typically ridden downhill and is a crowd-pleaser for all-around riders who like speed.
Chutes & Ladders (Upper & Lower Portions)
-
Length: ~5-7 miles, depending on start/finish
-
Difficulty: Intermediate
-
Why ride it: It's a favorite for adrenaline. After climbing Prime Cut to get to Chutes & Ladders, you hit steeper technical pitches, short punchy climbs, and then a smoother playground of fast, swoopy descent. Not beginner-friendly on the technical sections.
Zippity Do-Da
-
Length: ~2.4–4.5 miles depending on start/finish
-
Difficulty: Beginner to Intermediate
-
Why ride it: There isn’t a dull moment on Zippity Do-Da. Plenty of adrenaline-boosing terrain, but still approachable. This is a classic flow trail, with lots of rolling hills with steep descents.
Joe’s Ridge
-
Length: ~2 miles, not including your chosen access trail
-
Difficulty: Intermediate
-
Why ride it: Great views of the area, plus a few more trees than the other trails. There’s a gentle climb with a few steep spots at the front, but it soon opens into a fast downhill track with lots of good flowy action.
PBR (Pumps, Bumps & Rollers)
-
Length: ~2.2 miles, not including your ascent
- Difficulty: Intermediate
- Why ride it: The trail itself is intermediate, but expert riders can have a great time on this one too. Lots of…well, pumps and bumps and rollers. Get air if you can, or just enjoy the rolling!
PBJ (Pumps, Bumps & Jumps)
- Length: ~3 miles, not including your ascent
- Difficulty: Easy to Intermediate
- Why ride it: Smooth, flowy, and just plain fun, PB&J is often the trail people graduate to after PBR. It’s a touch longer and features a mix of mellow climbs, playful rollers, and swooping berms that feel like they were made for grins. The trail winds through classic desert scrub with wide-open views of the Book Cliffs in the distance, giving riders plenty of scenery to pair with the ride’s rhythm.
When To Go & Trail Etiquette
Best seasons: Spring (once trails dry), fall, and winter (especially when it’s a mild winter). Ride in the mornings during summer to avoid heat, as many of the trails are relatively exposed. Trails can be snow-free by March, but summer temps can be hot and windy. Plan for limited shade and bring plenty of water.
If it’s wet, don’t ride: The bentonite clay becomes very sticky and destructive when wet — you’ll ruin the surface and get nowhere fast. Wait 24–72 hours after rain depending on conditions.
Trail use & direction: Many 18 Road trails are designed for directional flow. Watch signage and yield appropriately (uphill riders yield to downhill where indicated, but check local signs). Pack out trash, avoid cutting switchbacks, and respect camp regulations.
