Hamilton Pool Preserve, 24300 Hamilton Pool Rd., is a natural swimming hole and grotto formed by water erosion over thousands of years. Today the pool is surrounded by limestone outcroppings and features a 50-foot waterfall, nature trails and picnicking areas.
Note: The rugged .25-mi. trail from the parking lot to the pool includes steep, uneven steps leading down into the canyon; proper footwear is recommended. The pool may be closed if bacteria levels are too high; phone ahead to confirm schedule.
Guided tours are available. Picnicking is permitted.
