What the picnic area is like

Picnicking here is trail-based. Two accessible tables sit under a tree beside the main Warren Richardson lot at the end of Channel Drive, and more tables are scattered along the shore of Lake Ilsanjo, a 26-acre lake reached by a roughly one-hour, 2.5-mile climb through fir, bay and redwood forest into open oak meadows.
