Cuba has over 3,000 miles of coastline and its extensive underwater attractions draw divers from all over the world. The crystal clear water and warm temperature make for easy viewing of abundant multicoloured fish, barracuda, sea turtles, lobsters, anemones and, on occasion, sharks. Nearly all the major resorts have diving centres, but the most recognised sites are Cayo Largo, the Jardines del Rey archipelago, the Isle of Youth off the south coast and Maria La Gorda on the western tip of Cuba. These last two sites require substantial diving experience. Many all-inclusive hotels offer diving lessons for beginners, but those wishing to undertake more advanced dives will need to take proof of their qualifications and have fully comprehensive travel insurance.
