Mountain Biking Lumpy Bumpy

*****   Add a review
#54 of 112 mountain bike trails in New Jersey
#4,259 in the world

Lumpy Bumpy is a crazy singletrack trail in the Allamuchy North trail system. It is unmarked, so it is hard to find. The trail is for experts only, and I recommend riding it with a dual suspension bike. It has many huge rock rollers and 180 turns, with some crazy rock gardens at the bottom of the trail.

    This trail is by far the most difficult in the whole trail network. Large rollers and rock formations to ride on, very difficult at times to follow the trail, and at the end a switchback with the craziest rock gardens. It's basically unidirectional unless you want to walk half of the trail. You can get on it from the green trail.

    My favorite trail in Allamuchy. Crazy rock gardens and rollers. Also has its fair share of drops.
