Santa Rosa Island Access is reached via Island Packers ferry service (approximately 3-hour crossing from Ventura Harbor) or charter flights from Camarillo Airport, landing at Bechers Bay pier.

The island offers exceptional opportunities for experienced kayakers and backpackers, with backcountry beach camping available mid-August through December along 55 miles of undeveloped coastline, though visitors must be prepared for strong winds (30+ knots common), rugged terrain, and self-sufficiency as no services are available on the island.

Water Canyon campground provides 15 primitive campsites with basic amenities, and fishing is permitted outside three marine reserves with a valid California fishing license.
