Bottle Beach State Park in Washington, USA - map and visitor information

Research checked: 2026-10-30. Check linked official notices before travel.

Bottle Beach State Park in Washington is a day stop for watching shorebirds on Grays Harbor. Its accessible interpretive trail leads to viewing platforms beside restored habitat. Plan a quiet walk here, with no recreational dogs, bicycles or fires.

Watch feeding birds from the trail

Migrating birds use the offshore mudflats to feed on amphipods. Late April and early May bring the spring peak described by the park’s history account. Binoculars let you observe feeding behavior without approaching the birds.

Know before you go

Fees, hours, and seasonal access

Keep the outing on the pedestrian route

Use the interpretive trail and viewing structures for the visit. Motor vehicles, horses and bicycles cannot use the trails. Keep time to return before dusk.

Protect the feeding and resting habitat

Recreational dogs cannot visit, but service dogs are welcome. The narrow November–February exception allows leashed hunting dogs to pass through toward adjacent hunting land. It does not allow hunting in this park. Fires are prohibited at all times.

Ask about an organized visit

Contact park staff before arranging an organized activity, and describe the group and intended use.

Find the Grays Harbor trailhead

Navigate to 33 Ocosta 3rd Street, Aberdeen, WA 98520. The official park page provides directions and visitor information. This is a shorebird viewing destination, not a driving route across the tide flats.

Other coastal parks by road

Twin Harbors State Park is on WA-105 in Westport, at number 3120. Its Schafer Road beach access is for pedestrians only. Westport Light State Park is at 1595 Ocean Avenue. At that separate oceanfront destination, use designated access routes around unstable dunes and sand cliffs.

Observe before moving on

Follow the 0.7-mile interpretive trail and stop at its two viewing platforms or blinds. The short route leaves time for patient bird observation rather than a long hike.

Specific accessible features

The park lists accessible parking, an ADA-accessible trail, boardwalk and restrooms. Ask staff about the features needed for your visit. The Discover Pass information explains vehicle parking terms and the permanent disability placard exemption.

A park shaped around habitat protection

The Ruby Egbert Natural Area designation covers more than 90 percent of the park. It emphasizes preservation, restoration and interpretation, with low-intensity outdoor recreation.

From Ocosta to a state park

Bottle Beach takes its name from debris left by the vanished Ocosta development. The state park was dedicated on July 9, 2009. The official history also describes the Coast Salish peoples whose traditional territories include the site.

A food supply for migrating shorebirds

The birds pause here to feed and recover during migration. Amphipods in the mudflats provide that food supply. Leave space for feeding and resting rather than trying to draw birds closer.
