“The most direct way to get to the gem of the park, Lumpy Bumpy.
”
This trail can be described as a means to an end. Although I ride this trail almost every time I hit Allamuchy, I use it simply to get to Lumpy Bumpy, the best trail in the park. Turn right off of Waterloo/517 Trail (White), and start your climb up the Four Bump Bypass. This trail becomes washed out very quickly, and turns into one of the more technical climbs you'll encounter in the park. Stay right whenever you can, and after a good 300 foot ascent, Lumpy Bumpy will be on your left.
