Autumn is an excellent time to travel to the park, as well as for diving, as the days are usually sunny, with minimal winds and clear ocean water. The islands within the park extend along the southern California coast from Point Conception near Santa Barbara to just north of Los Angeles. Park headquarters and the Robert J. Lagomarsino visitor center are located in the city of Ventura. The park is open all year. The visitor center is closed Thanksgiving and Christmas.
Climate is mild, with little variation in temperature year round.
However, be prepared for high winds, fog, and sea spray at any time. Visitors to the islands should dress in layers, with short and long pants, windbreaker, hat, sunscreen, and waterproof outer clothing. Wear sturdy hiking shoes with non-slip soles. Ventura is located 70 miles north of Los Angeles and 30 miles south of Santa Barbara. The visitor center is located at the very end of Spinnaker Drive in the Ventura Harbor.
