The summer Trade Winds and winter swells of the Atlantic make this a year-round surfers' paradise, with more exposed areas on the north and west shores such as Corralejo and El Cotillo proving most popular. Wind surfing takes places at locations around the island. Sailors, scuba divers and big-game fishermen are all drawn to these clear blue Atlantic waters where whales, dolphins, marlin and turtles are all common sights. With many hills present throughout the Island, hikers are also attracted to this Island.
