Two crescent coves framing a grassy lawn, with hand-built 1930s stone picnic shelters and some of the park's richest tidepools. A carved cedar story pole stands watch at the water's edge.
Two crescent coves open in front of you, side by side, with a grassy day-use lawn strung between them like a hammock of green. Pull in and you'll see the old CCC picnic shelters back under the trees — stone and heavy timber, built by hand and still standing, still smelling of woodsmoke on a good afternoon. Down on the gravel, the water draws back and leaves a world behind it: this is one of the richest tidepool shores in the whole park. Standing tall at the edge of the lawn is a carved red-cedar story pole, the figure of a woman watching the water — that's Boone's to tell, and he'll get there. For now, just know whose shore you're standing on. Park honest: check that gate as you came in, since Rosario's day-use has carried seasonal limits some years. Then cut the engine, and the audio waits while you walk.
Time it with the tide and this is the best low-tide treasure hunt on the tour. Walk down to the nearer cove and kneel at the waterline: ochre sea stars in orange and deep purple gripping the rock, green anemones folded shut, little crabs sidestepping under the weed. Look, don't pry — every one of them is breathing through this low water, waiting for the sea to come back. From there, take the flat stroll across the lawn to the second cove, maybe four-tenths of a mile out and back, the kind of easy you can do in sandals. Watch the carved story pole as you pass and give it a respectful beat. Spread lunch under one of those CCC shelters and you're eating where Depression-era crews ate their own. Two things to remember: the rocks get slick where the weed is, so plant your feet, and put back every shell and stone exactly as you found it. The crescent you leave should look untouched, same as the tide left it.
