The Scottish Seabird Centre's wildlife adventure boat trips are operated in partnership with local operator Seafari Adventures (Forth) from North Berwick Harbour, to the islands from Easter to October. The Centre also has exclusive landing rights for the Bass Rock, owned by Sir Hew Hamilton-Dalrymple, and home to the world's largest colony of Northern gannets. Landing Trips to the Bass Rock are a very special, sense busting, wildlife experience as the numbers of northern gannets have soared to 150,000 over the years. Landing trips to the Isle of May are available departing from North Berwick, as well as hour-long trips around the Bass Rock on board the 55-seat catamaran and 12-seat RIBs.
