Gran Canaria, the third largest of Spain’s Canary Islands, is known for its volcanic landscapes, white sand beaches, leafy mountains, and nightlife. Travelers with an appetite for adventure can scuba dive to coral reefs, explore desert dunes on a camel, or trek to Roque Nublo. For culture vultures, walking tours of UNESCO-listed Vegueta (Las Palmas Old Town), and the historical towns of Teror and Arucas are bound to impress, while those seeking rest and relaxation should head for the beach resorts of Maspalomas in the south. Other must-see activities include dolphin and whale watching off the coast of Puerto Rico, and sampling local Spanish cuisine on a food tour.
