This is a park in the woods constructed and dedicated to mountain biking. It's on private land, so no pesky rangers telling us "you can't ...", skinhead ATV riders looking to run us over or elderly Land's End-granola hikers having heart attacks because dear-Lord! there are mountain bikers out here, too! Owner & designer Cliff Krolick has done a great job over the years creating a full network of singletrack, including some climbs, tricky descents and stunts.
Site has a lodge and yurt for indoor stays, with kitchen & bathrooms, hot tub & camping sites. Definitely worth a 2-3 day stay to explore it all.
