Trail System
Built for Every
Skill Level
Barnwell Mountain's trail system spans the full 1,850-acre property with over 27 miles of mapped, rated, and volunteer-maintained trails. Every trailhead is clearly signed — a system so well designed it's been adopted as a model by other parks nationwide.
Trails are rated using a diamond system from 1 (Beginner) to 5 (Extreme), so you always know what you're getting into before you drop the transfer case. Whether you're running a stock Tacoma or a built-out 80 Series, there's a trail with your name on it.
The 16-mile Adventure Trail offers a less demanding route across the property — perfect for overlanders, passengers, and anyone wanting to take in the scenery without the adrenaline.
Trail Tips
- Know your rig — pick trails rated for your build
- Never wheel alone; buddy up or join a trail group
- Carry a recovery kit: tow strap, shackles, Hi-Lift
- A winch is your best friend on 4 and 5 diamond trails
- All trails are clearly signed — follow the markers
- Respect other riders and yield to uphill traffic
- Pack out what you pack in — keep BMRA clean
Diamond Rating System
Know Before You Go
All trails at BMRA are rated using the diamond system. Match your build and experience to the right level — and know your limits before you hit the trail.
Beginner
1 Diamond
"4WD needed occasionally. Relaxing ride with few tough spots."
Stock 4WD vehicles with low range and reasonable clearance are all you need. Expect sand, shallow water, small-to-medium rocks, light mud, and rolling hills.
Requirements
- › Stock 4WD with low range
- › Reasonable ground clearance
- › Good for first-timers
Intermediate
2 Diamonds
"4WD needed a lot. Stock vehicles and tires OK."
Larger tires and a limited slip differential will help. A transfer case ratio of 2.5:1 or higher and 50/50 locked transfer cases improve performance noticeably.

- › Limited slip differential recommended
- › Transfer case 2.5:1+
Advanced

Solid front axles, sway bar disconnects, and real driving skill become critical here. Expect bigger rocks, steeper grades, and tighter lines.
Requirements
- › Large aggressive tires
- › Rear locker recommended
- › Solid front axle
- › Sway bar disconnect helps
