The bluff-top park on the headland that gave the town its name, with a network of paved walking paths, viewpoints over the harbour and ocean, and an interpretive nature centre with displays on the local geology, plant life, and seabirds. The whole loop takes about an hour at an easy pace; benches are placed at the best viewpoints.
The view south takes in the harbour breakwater, San Clemente Island on a clear day, and — in winter — migrating grey whales passing close inshore. The view north covers the bluffs as far as Laguna Beach. Sunset from the western end of the loop is one of the best in Orange County. Free parking at the Nature Interpretive Center; the trails are open dawn to dusk.
