Joseph Whidbey State Park offers one primitive Cascadia Marine Trail campsite accessible only by human-powered watercraft (kayak, canoe), available first-come, first-served for $12/night with a vault toilet and picnic tables nearby.

The park features 3,100 feet of Strait of Juan de Fuca shoreline with easy beach access, making it ideal for paddlers seeking a remote camping experience, though be aware of potential strong winds and large surf from the strait.

Note that the park is closed November 1–March 31, and noise from nearby Naval Air Station Whidbey Island jets may occur during training missions.
