A 1-kilometer (0.6-mile) walk alongside a marsh and over a sand dune takes you to the northern end of the Great Beach, called Kehoe Beach. Once at the beach, turn left to explore a stream meandering its way into the Pacific Ocean. To the right, giant dunes make explorations fun. Follow the beach further north to see the dramatic juxtaposition of rocks. The first cliffs you see are the smooth Laird sandstone, which change abruptly to granite. A reverse fault displaced the sandstone against the granite upon which it was deposited, creating a continuous cliff made of very different rock types. Dogsare allowed on a 1.8-meter (6-foot) leash on this beach to the north of the trail. Dogs are not permitted south of the trailhead as this area is protected habitat for the endangered snow plover.
