Santa Rosa Island Campground offers 15 primitive tent sites in Water Canyon, accessible only by boat (3-hour crossing from Ventura) or plane, with each site featuring a wind shelter, picnic table, food storage box, flush toilets, and potable water.

The campground serves as a base for hiking, kayaking, and beach exploration along the island's 55-mile coastline, though strong northwest winds (30+ knots common) and rugged terrain require experienced outdoor skills.

Reservations are required up to 6 months in advance at $15/night, with a typical 3-day minimum stay due to boat schedules.
