About Agate Beach at Sue-meg State Park in Trinidad, California

Agate Beach is the large main beach at the north end of Sue-meg State Park near Trinidad. Beachcombing and agate hunting are excellent along this mile-long beach. The park has hiking trails, campgrounds, and historical sites to see.

Getting to this beach requires a steep twisty hike from the parking lot at the edge of the bluff (restrooms at the trailhead). The descent is about 200 feet but it feels like more than that, especially when going back up. The trail puts you onto the beach near the bottom of Agate Creek which is rarely more than a trickle. Other trails allow you to explore up the creek valley.

Agate Beach continues northward toward Big Lagoon Beach and offers superb beachcombing along the way. Driftwood, agates (and other stones), seashells, and unique items that have drifted across the Pacific Ocean could be found on your beach trek. We’ve found all sorts of things while walking Agate Beach.

The park itself is packed with hiking trails that lead to grand vistas (like Wedding Rock), rocky points (like Palmer’s Point), overlooks, and other places to discover so get a map when you pay the fee to enter Sue-meg State Park. There are three campgrounds in the park if you want to stay here overnight. Book your spot well in advance if visiting in the summer (visit ReserveCalifornia online).

Don’t take any of the agates! We saw women filling socks with all of the pretty little rocks that they could find. This is one of the best beaches in the area and it’s never crowded. You can walk on the beach for a couple miles to Big Lagoon and back. We love this beach! Please leave the agates for other people to find!
