A fun mid-technical loop with optional drops, small to medium sized rollers (both down and up), tight corners, roots, rocks, and one steep dirt pitch. Can be tough to follow in spots due to the spider web of trails that often cross it (many of them are unmapped). The whole loop is a pretty good time, in either direction (better direction indicated on map).

 Dry. Minor debris. But mostly running great! Far more challenge than the green rating of this trail suggests (Rating should be changed)

 Some of the trail is overgrown or impossible to find/stay on but there are usually alternative ways through it.

      This is actually a solid mid-level tech trail, with a variety of smaller rollers, roots, rocks, and trail variations that all add up to a lot of fun. Definitely should not have been rated a green trail - this trail is not for beginners at all.

      We hope you've been enjoying Trailforks!
