Brain Wave offers one of the best flat flow sections in BDOS and one of the more technical intermediate trails in the area. Brain Wave is easily distinguished into two very different sections. The first, from Spooky to Grassy is fast, fun and flowy, and easily just a green circle. After Grassy and all the way to the Sasquatch Extension is a much more technical trail, which is what earns Brain Wave its intermediate status. While the tech isn't anything special, compared to the mellower XC trails offered here, it's something to challenge progressing riders. The trail is most technical on the north side of the Powerline Road near Sasquatch Extension. If you are a beginner, or simply want to avoid the tech of the second half simply turn right on grassy at the intersection and then either continue to the Powerline Road, or turn right again on the other Grassy, which will take you right back to Spooky.

Access Info

Easiest to access off of Spooky, at the first fork in the trail follow the signs for Brain Wave to the left.

       If there's any beginners out there, this trail is easily a Green Circle from the intersection with Grassy to the intersection with Spooky.
