Twenty-eight miles west of San Francisco, the Farallon Islands rise from the Pacific as one of America's rawest great white shark frontiers, where expedition cage boats target the autumn window when adult sharks hunt elephant seals around the archipelago. Access is weather-dependent and strictly regulated, with limited permits and small group sizes preserving the wild character of every trip. September through November aligns with seal pup activity and the sharpest seasonal spike in shark presence.

Up to 75% sighting chance in Farallon Islands (California). Best months: October, November, September.
Licensed expedition operators typically run September through November, timed to elephant seal pup activity and the sharpest autumn spike in adult white shark presence around the archipelago.
Full-day cage expeditions from San Francisco typically run 900 to 1,400 USD per person (2026 prices), reflecting limited permits, small group sizes, and long offshore passages.
California and Gulf of the Farallones National Marine Sanctuary rules strictly limit operator permits, ban chumming, cap passenger numbers, and require cage-only observation. No open-water shark diving is permitted.
Trips depend on offshore swell and wind from San Francisco or Sausalito marinas. Full-day passages of 28 miles each way are common, and weather cancellations due to heavy swell are frequent even in season.
No. This is a wild expedition site under strict regulation. Surface cage sightings are strong in peak season but never guaranteed due to weather, thermoclines, and shark movement around the seal colonies.
