Picture-postcard beaches with powdery sands and protected coral reefs are scattered throughout the 378 islands, many uninhabited, in Panama's San Blas islands or Comarca Guna Yala, homeland of the country's most famous indigenous people. Scuba diving is prohibited in the turquoise Caribbean waters, but Kuna culture - including the famous molas - make this more than a beach destination. Regular air service from Panama City is available to several the larger islands, but the only way to get around the 100-square-mile paradise is by boat.
