Island Packers offers a day trip to Santa Rosa Island for two (2) adults. 

At 84 square miles, Santa Rosa is the second largest of the eight Channel Islands. There are two relatively high mountains on the island; Black Mountain, 1298 ft (396 m); and Soledad Peak 1574 ft (480 m).

The trip to Bechers Bay from the Ventura Harbor takes approximately two hours if the boat takes the northerly route, two hours and 15 minutes via the smoother and preferred southern route. If the boat is stopping at Scorpion Anchorage, or Prisoners Harbor, Santa Cruz Island, you can add an additional 30 minutes to the crossing. The preferred route takes a track along the south side on Santa Cruz Island because waters are usually much calmer there.
