About Rosario Beach

Rosario Beach is on the Fidalgo Island side of Deception Pass State Park, below Rosario Head. It is a pebbly, driftwood-strewn cove reached by a short, fairly steep path, and Beachcombing Magazine names it as one of the better beachcombing beaches in the islands north of Seattle.

Sea glass at Rosario Beach

Soft blue, green and white glass among the pebbles, alongside rich tidepools.

Visiting Rosario Beach

Parking
Limited parking, so arrive early; state park fee (about $10) unless you have a Discover Pass.
Safety
Check the tide times before you go and head out on a falling tide, so you're never cut off. Keep away from the bottom of cliffs, wear sturdy shoes on rocks, and only take sea glass and other man-made rubbish: pebbles, sand and shells should stay on the beach.
