Tucked away behind Lopez Lake is one of the most scenic spots on the Central Coast, Big Falls. The two waterfalls along Big Falls Creek are some of the best around and worth the trek. To get to the trailhead, turn onto Hi Mountain Road, located just before the entrance to Lopez Lake Recreation Area, and then veer left onto Upper Lopez Canyon Road.
This four wheel drive trail will take you across Lopez/Big Falls Creek several times, through a sycamore and oak forest and to the base of 40-foot Lower Big Falls and, further up the trail, 80-foot Big Falls.
