Bottle Beach State Park sits on the tide flats of Southern Grays Harbor, where it plays host to more than a million migratory shorebirds and sea birds in spring. The park’s ADA-accessible trail is an official Washington State Birding Trail, designated by the Audubon Society. More than 130 bird species, including raptors, have been known to alight for a quick meal at Bottle Beach.
The boardwalk and trail lead past Redman Slough to a picturesque beachhead viewing shelter. Drop down to the mud flats below, and explore remnants of a dock built in 1890 to serve Ocosta, a boom town that quickly went bust and disappeared by the 1950s.
Bottle Beach does not allow dogs or camping, but yurts and cabins, and pet-friendly RV sites are available at nearby Twin Harbors and Grayland Beach state parks.
Bottle Beach State Park is a 75-acre day-use park with 6,000 feet of shoreline on Grays Harbor. The open tide flats are the park's most significant feature. The park sits on the site of Ocosta by the Sea, a ghost town once slated to be the Pacific Coast terminus of the Northern Pacific Railroad and a major port city.
Discover Pass: A Discover Pass is required for vehicle access to state parks for day use. For more information about the Discover Pass and exemptions, please visit the Discover Pass web page.
The Bottle Beach Interpretive Trail consists of a trail-head and parking lot, 0.7 miles of ADA accessible trail, three wildlife viewing platforms or blinds, and approximately 9.5 acres of restored habitat.
The trails are for pedestrian use only. No motorized vehicles, horses, or bicycles allowed.
Dogs are only allowed at the park during hunting season, from November through February. Service dogs are allowed at all times.
Bottle Beach State Park is located on the historic town site of Ocosta. Near the end of the 19th century, plans were made to establish a deep water port in the Grays Harbor area. The Northern Pacific Railroad chose Ocosta for its Pacific Ocean terminus, thus providing an avenue for imports and exports to find their way by land. As the boom ensued, prospective investors from the east were solicited, "...nothing can prevent making this the most important harbor north of San Francisco, if not the chief harbor of this Pacific Coast," read an early advertisement.
Soon, the Ocosta settlement sprouted with a school, three hotels, three churches, a bank, post office, the Ocosta Lumber Company, and the Ocosta Brewing Company. Aspirations for an ocean harbor soon deteriorated as an economic downturn, railroad realignment, and sedimentation undermined the possibility of Ocosta becoming a principal port. Time slipped away as Ocosta by the Sea slowly became the landscape you see today.
