Both the south and north parking lots have trail heads. One trail system goes south and the other goes north up to Top of the World, the large at the northeast side of the park. The southern trail is a large loop that is bisected by another trail so you can ride it as a figure eight. The north trail is also sort of a figure eight with each of the downhill sections in a separate loop (one southwest and one northeast), but there are a few additional trails that branch around. Take the center trail first to get around the backside of the downhill sections so that you can descend.
