Caleta de Fuste (also known as El Castillo) is a rollicking tourist destination with wide beaches and outdoor sports, including sailing, diving, and windsurfing. Travelers enjoy sharing the blue waters with the  turtles and dolphins, as well as hitting the greens at the luxurious Fuerteventura Golf Club.  If you're looking for equal parts adventurous-trip and relaxation-central, you'll find it here with a day of snorkeling or trike riding followed by lounging on the serene sand beaches.
