From Los Angeles take the 5 north to the 14 north. Exit Pear blossom cut off. Turn Right at Barrel Springs And follow to the end of the pavement and Turn Right on Chessbro Which will take you straight to Lil Rock Dam. This place is awsome for swimming & Kayaking. There are several different jumps here and even trees that you can climb up and jump out into the lake from . To find the big jump I posted stand in the parking lot & look across the dam and its in the left back corner….. Climb up the left side for easier access.
