Yeah I've been there quite a bit, it's a good setup - there are quite a few runs, mostly fairly short but a good variety, mixture of fun DH courses, 4X, dual slalom etc and some bigger jump lines if you're into that sort of thing.
Zoom down the hill, push or ride back up, repeat until tired. Really good for skills practice.
You can't really get lost inside the main park.
There is an XC loop around the outside that I used to enjoy as well but I haven't ridden that in a few years and not sure how clear the signs are, think that bit is 'unofficial'.
