Start at the lowest elevation in Leominster SF and end your ride with a downhill

Park at Gate 10 (which is at the intersection of Lucas Rd and Justice Hill Rd in Princeton). There is no lot at this gate only parking on the side of the street. Please do not block the gate!

This route will start with the Sportsmen Club trails which are a fun way to climb. Hit local favorites: Split Rock, Organism and Jane Fonda's Workout before a fireroad climb towards the western side of the park. Climb up Wolf Den Road and hit the upper part of Wolf Den Trail before riding two more local favorites, Frick and Hillybilly Heaven, in the downhill direction.

This route can be ridden by intermediate riders but will be a lot of fun for all levels.
