San Miguel Island Access is reached via boat from Ventura Harbor (Island Packers concessionaire) or private boat, with landing at Cuyler Harbor via skiff—conditions can be challenging with 8-foot seas not uncommon.

The island offers primitive camping (9 sites), ranger-led hiking including a popular 14-mile round trip to Point Bennett for wildlife viewing, and access to tide pools and beaches, though strong persistent winds (30+ knots) and cold water (below 60°F) require experienced paddlers and proper preparation.

A permit and liability waiver are required for all visitors, and all gear and water must be carried in by foot (1-mile steep hike from boat landing).
