There are a huge number of companies offering boat trips to tourists and these vary from a 'booze cruise' on a cruiser offering lunch, drinks and watersports to a trip around the island on a sailing boat or catamaran. One of the main attractions is the chance to see whales and dolphins in the wild. Visitors on most trips spot whales, while dolphins are not so much of a certainty but are often seen very close to the boat. Trips go from either Puerto Colon in Playa de las Americas, or from the port at Los Cristianos and most operators offer a free bus service from the larger hotels in the main resorts.
