Rocky Pacific islands, seasonal manta encounters and relaxed Guanacaste beach bases.
Overview
Base yourself in Playa Flamingo or Potrero for guided day boats to Costa Rica's Catalina Islands. The underwater draw is volcanic rock, boulders and pinnacles visited by eagle rays, white-tip reef sharks, schools of fish and sometimes oceanic manta rays. Manta-focused operators identify December to May as a possible encounter season, with February and March emphasized, but sightings are never assured. Shore beaches are for beach time, not a substitute for a checked Catalina snorkel boat. Dedicated freedive courses also operate in Flamingo Bay. Tamarindo can supply lodging or operator pickup without turning its surf beaches into reef-snorkeling sites. Verify pickup, current, visibility, boat safety and conditions directly before paying.
