Double Bluff State Park, also known as Useless Bay Tidelands, is a 24,354 foot stretch of beach on the southwest shore of Whidbey Island. The beach is wide and sandy at the access and becomes rockier with cobble and large boulders towards the west. Two large unstable bluffs are the major feature of the uplands. Clam habitat is patchy and restricted to the cobble areas in the lower intertidal. While butter clams are the species most commonly harvested at this beach, native littleneck clams, cockles, horse clams, eastern softshell clams, and macoma clams are also present in lesser numbers.
From the south: From the Mukilteo ferry terminal drive north on Hwy 525 for 8.3 miles. Turn left on Double Bluff Road and follow to the end.
From the north: Take Hwy 20 south through Oak Harbor and continue on Hwy 525. Turn right onto Double Bluff Road and follow to the end.
There is parking space for up to 24 cars.
While the tidelands are a State Park, Double Bluff Park (the upland portion of the park) is operated by the Friends of Double Bluff and Island County. There are bathrooms, outdoor showers, picnic areas and a pay phone at the access area. This is an off-leash dog park. This beach features views to the south of Mt. Rainier.
