About this site
Caño Island Biological Marine Reserve sits off the Osa Peninsula on Costa Rica's southern Pacific coast, reached by boat from Drake Bay or Sierpe. The island and its surrounding waters are protected as a marine reserve, part of the broader Osa conservation area known for its biodiversity. Diving here reaches a maximum depth of around 30 metres and is generally rated suitable for beginners. Divers have also reported eagle rays passing through the site, and there has been at least one report of a dugong in these waters.
