Bonito's scuba scene is small but world-class in its niche: guided freshwater dives in sinkholes and flooded caves. The headline is Abismo Anhumas, where a 72 m descent drops you into a vast cavern lake for clear-water diving. Lagoa Misteriosa adds blue-sinkhole depth with operator-set depth limits by certification, and Gruta do Mimoso delivers a flooded-cave feel in calm conditions. Expect fixed schedules, strict briefings, and conservation rules, not casual drop-in diving. Some sites offer batismo dives with an instructor; certified divers should bring cards and logs.
