this trail is great if you can do shuttle runs. real tight twisty singletrack with a few small jumps. lots of tree roots to manage, a few rock gardens, some off camber sections and then there is a pretty good sized hip to hit in the middle. there is only one real small climb in the middle (takes about a minute if u hammer up it) then you get to an open space where there is a big open lookout area with a view of the whole S.F. bay. going down from this spot is real fun, switchback section with pretty big berms that u can really rail through.<br />

check your speed as there is some blind corners and this is a shared trail with hikers. the hiker hippies here get fiesty sometimes
go up skyline blvd towards chabot space and science center. you will see signs for the science center, and next to the entrance for that will be a parking lot for hikers, etc. park there and the trailhead is across the street next to the big sign that says "sequioa arena" the good trail starts off the the right, there is a log halfway blocking the entrance that has been built up into a jump.<br /><br /><br /><br />there is a round table pizza next to hwy13 u can park at the bottom for doing shuttle runs.
