TTFs on TrailDrop, Jump, Gap Jump, Rock Face, Other
A very fun trail with several rock rolls, a couple drops and even a fun jump. The sand will challenge you to carry enough speed for the features. . . but it's a good idea to check them out prior to hitting the drops and rock rolls anyways. . . especially after any level of precipitation.

Trail has mostly optional features but I rated a double black because if you do the features, the trail is pretty gnar
wobblegoblin
Trail is INCREDIBLY SANDY, hope you know how to ride your back wheel in ankle deep sand, especially if you hope to carry enough speed for the jumps/drops/rock rolls.
We hope you've been enjoying Trailforks!
