Our favourite trip on the Osa Peninsula was to the Caño Island Biological Reserve. It’s a beautiful little island and can be reached in just 45 minutes by boat from Casa Corcovado Jungle Lodge making it a perfect daytrip. On the way out, we saw dozens of Spinner dolphins feeding. And on our return we were lucky enough to catch the juveniles playing – jumping and spinning high out of the water up to about 2 metres. So fun to watch. There is coral surrounding the island’s coast and it makes for a good couple of hours snorkelling before a packed lunch on the beach. We saw a deadly starfish, Puffer fish, Dog Snapper, Big eyed / blue jacks and Yellow finned tuna. But the thing that blew me away was the 200 strong school of barracuda which swam below us and around us for almost 15 minutes. Frightening and beautiful at the same time as they look so angry in the mouth.
