• 5 ★ 0.0 • 3,415 ft • 10 ft • 4 • • hike
Following the trail left to avoid summiting Gachen Mountain. A few different exits, but this one is the most easy to ride.
• 5 ★ 0.0 • 646 ft • 27 ft • 4 •
Access from the road is just off the switchback. That said, this is a very hard and rooty climb. Most will want to hike a bike until you are on the next peak. Just follow the ridge until the peak where the trail will become obvious down...
• 80 ★ 0.0 • 2,005 ft • 0 ft • 4 • • hike
Designed as a hiking trail, there are a fair bit of steps but they are long and spaced so very ridable down. Likely too much for uphill. You are better using the gravel/dirt roads that parallel this route just east of here to get up here.

A few of the pushes to the small summits on the ridge will likely be a hard sprint or hike-a-bike. But many stretches are rideable and this connects these two regions.
• 80 ★ 0.0 • 771 ft • 0 ft • 4 • • hike
A steep drop along a rocky ridge bringing you one step closer to nirvana.
