The San Blas islands are on the Caribbean side of Panama. The island group comprises 365 islands, only a few of which are inhabited. The islands lie in an autonomous region and have been ruled by the Kuna native Indians since 1938. There are no mosquitos, perhaps one of the reasons the native Indians chose to settle here. They go out to fish for crustaceans in special wooden boats, called "Cayucos". Unlike the other tribes of the Caribbean, the Kuna are dressed top-to-toe at all times, usually in colourful traditional costumes. For tourists, the San Blas Islands represent a beautiful, untouched diving area that people are reluctant to leave on account of its sandy beaches in sheltered coves and its warm, turquoise-blue waters.
