The islands of the San Blas Archipelago are strung out along the Caribbean coast of Panama from the Golfo de San Blas nearly all the way to the Colombian border. San Blas is a series of 378 islands of which only 49 are inhabited by the fiercely independent Kuna Indians. Although only a 20-minute plane ride away from Panama City, a trip to the San Blas islands will transport you 20 centuries into the past. The Kuna Indians, who run all the islands as an autonomous province with minimal interference from the national government, have maintained their own economic system, language, customs and culture, with distinctive dress, legends, music and dance and thus have avoided traditional tourism development. The economy of the islands is based on coconut sales, fishing and tourism, and they offer travelers good snorkeling and swimming. Facilities are few and simple, as is the food. The area is surrounded by reefs, some of the oldest in the world, and offer wonderful snorkeling opportunities
