Take a small private 3 hour boat tour to Los Arcos, an underwater national marine park reserve. Los Arcos is an excellent and very safe snorkel site to start for experienced and not so experienced snorkellers. The reef depth range is from 3-30 feet/visibility between 15-50 feet year round. Fish you can expect to see, angel fish, puffer fish, cornet fish, parrot fish, and damsels that feed on the shallow reefs of Los Arcos.
