This trail rocks, seriously, it is a mix of sandy rock and this tiny little gravel. There is not a ton of speed, as the turns are tight, but there is a cool little bridge between to massive rocks and there are some cool drops that you can air out on. The transition between super grip and loose rock keeps you alert

 Sandy and very loose gravely rocks sections, braking is iffy, especially off of the two drops that you need to turn immediately after.
