The trip in short
From July to October it happens on both coasts at once. At Tortuguero green turtles crawl up the beach at night to lay their eggs; you watch with a guide, without a torch. On the other side of the country humpbacks from the south swim with their calves off the Whale's Tail of Marino Ballena. In between, the monkeys of Manuel Antonio. A trip for turtles and whales, in the green season.
