No permit required
No permit is needed to paddle the Salish Sea itself, but overnight camping is almost entirely at Washington State Parks marine-trail sites (per-night fee, first-come) or BLM sites in the San Juan Islands National Monument with their own capacity rules. Cascadia Marine Trail sites are reserved for non-motorized, beachable craft.
