Description

This is the first section of trail leading up from the main Hall Ranch parking lot. It's a steady climb all the way up to the junction with the Antelope trail.

This trail includes a 1/2 mile Rock Garden that can challenge all but the most advanced mountain bikers. It's a consistent climb with big moves up and over rock faces and features. It's rideable by advanced riders even without trials skills, but you'll work for it!

Less experienced riders can choose to park at the other smaller trailhead and ride the intermediate (but still fun singletrack) Antelope trail up to the same spot.

Climbing the rock garden section of Bitterbrush can be a humbling experience.

After a tough Bitterbush climb, point it for a short downhill before climbing up to Nelson.

The down never gets up to speed on account of some 'well' placed hiker corners. Old school like Adidas with no laces.

This is rediculous. Seeing how big these rock gardens are is one thing. Seeing how well some other riders get up/down them is another. This is way… 2.5mi

Some of the most fun I've ever had on a downhill. Love the grippy rock and the ability to be creative with your lines.

I'll admit I had shied away from this trail due to its reputation-I was missing out! Fun trail, super hard, but never felt like I was in mortal peril

Good ride with Bill K. Up is still extremely hard but down is a blast. Rode the Borealis fat bike cause Tallboy is in the shop for maintenance
