01
Best overall pick
Big Lagoon County Park Beach
Big Lagoon County Park • Wide Sandy Spit Between Lagoon And Ocean • Best For First-Time Visitors
A long sandbar with easy access to both calm lagoon waters and open-ocean views.
This is the go-to beach if you want the full Big Lagoon experience without much hassle. Day-use parking, restrooms, and a gentle launch area make it easy to paddle the lagoon or stroll out to the ocean side. Expect steady breezes, driftwood sculptures along the sand, and big-sky sunsets when the fog lifts.
02
Best for agate hunting
Agate Beach at Sue-meg State Park
Sue-Meg State Park, South Of Big Lagoon • Pebbly Cove Below Forested Bluffs • Great For Rockhounds And Tidepoolers
A rocky, wave-pounded shoreline known for agates, polished stones, and dramatic surf.
Reach this beach via a steep path down from the blufftop campground and picnic areas, trading convenience for a more secluded feel. The mix of rounded stones and surf-polished gravel makes it a favorite for patient agate hunters. It’s better suited to rambling, beachcombing, and watching the waves than to casual swimming.
03
Most scenic headland walk
Trinidad State Beach
Trinidad • Pocket Beach Framed By Sea Stacks And Headlands • Perfect For Photography And Sunset Walks
A classic North Coast scene with offshore rocks, a sheltered sandy stretch, and trails to sweeping overlooks.
Just a short drive south of Big Lagoon, this beach combines easy town access with rugged coastal drama. Trails from the parking area lead to sandy coves and up to clifftop viewpoints where you can watch fishing boats thread between sea stacks. Come at lower tide for more walkable sand and changing reflections in the tidepools.
04
Best for camping on the sand
Clam Beach County Park
Near Mckinleyville, South Of Big Lagoon • Flat, Open Surf Beach With Long Shoreline • Good For Dogs, Kites, And Long Walks
A broad sandy strand that runs for miles, with drive-up access and a relaxed county-park vibe.
Clam Beach’s long, level shoreline makes it a natural choice for beach camping, leashed dogs, and unhurried strolls with the sound of surf in the background. There’s plenty of room to spread out, fly kites, or watch the fog roll in over the dunes. It can be windy and the surf is powerful, so most visitors stick to the sand rather than the water.
05
Quietest nearby escape
Dry Lagoon Beach
Humboldt Lagoons State Park, North Of Big Lagoon • Wild, Little-Developed Driftwood Shore • Best For Solitude Seekers
Often nearly empty, this rough-edged beach feels far from the highway despite being close by.
Pull off near Dry Lagoon and follow the short path toward the shore to find a broad sweep of sand backed by marsh and low bluffs. Driftwood piles, birdlife, and the constant hush of the waves give it a quietly remote character. Services are minimal, so bring what you need and plan on simple pleasures: walking, beachcombing, and watching the clouds move over the water.
