Waverly is a great park. It is a combination of old ATB and four wheeler trails with handmade MTB single track....I believe in thanks to the KYMBA. The trails are somewhat technical with the park itself divided into a few different areas. There is no certain path to follow so experiment and find a loop you like. It's got tons of climbs, lots of half tight single-trac, and some decent downhills(One of which is called the Luge). Clockwise is the standard direction most follow.
