Experience and adventure in the Greater Farallones National Marine Sanctuary with shark specialists and expert naturalists. Visit the Devil’s Teeth, the feeding ground of the great white shark, and learn about the fascinating history of this rarely visited archipelago just 28 miles off the San Francisco shoreline. These Sharktober natural history trips focus on the history, geology and biology of the Sanctuary and San Francisco Bay. We only book in fall when the white sharks return and the weather is clement for our passengers and students, but also the best time to observe many species of whale, seabirds, fish and weird invertebrates.
Departing San Francisco’s famed Fisherman’s Wharf, these day-long expeditions are on the US Coast Guard certified 50 foot vessel the Amigo with a licensed and veteran captain and crew, with all safety equipment. These are shark education, marine conservation and emphasize the health of the entire marine ecosystem including marine protection in the Greater Farallones national Marine Sanctuary. Although we watch whales and seabirds, and seek sharks- these trips are conservation and outdoor marine education and are not explicitly shark watching trips.
These are permitted under NOAA but are not cage diving trips, nor do we chum of feed sharks.
Running 14 years, we operate under a permit from the Greater Farallones National Marine Sanctuary’s White Shark Stewardship Program. We have highly trained shark and wildlife experts and are permitted to deploy a decoy. We also use a hydrophone, and a small ROV for underwater recording and we often get to see the great white grin!
These trips are run by Shark Stewards LLC and are not associated with the Earth Island Institute.
