Folow the red route out of the top car park (hard work on a DH bike, fun on a 5-6″ bike), at soem point it comes to a fire road crossroads and the red route goes diagnoaly off this, folow it, dont try and skip it allong the fire road you’ll end up lost/at the bottom of the hill.
Recomend starting on the fast track for a warmup, the rest are tighter/steeper/twistier and mainly follow the push up track (so watch out on the way up as most tracks seem to cross it or go down it between sections).
Push up isn’t too bad, probably rideable on an AM bike.
