  • Full day of snorkeling in one of Costa Rica’s best snorkel and dive locations, the Caño Island Biological Reserve


12.5 hours door to door: (6:00am – 6:30pm)


The day begins at 6:00am, departing from Dominical on the Costanera Road. On the 1-1.5 hour ride to Sierpe, you will have the chance to see diverse wildlife, including sloths, tropical birds, and monkeys. You will also pass the Ballena Marine Park and your guide will explain its unique natural history and how it became the first park of its kind in Latin America. You will also catch a glimpse of the mysterious, ancient, perfectly round stones left by a now extinct civilization around 400 BC. In Sierpe, you will energize with a healthy breakfast.

Around 8:00am, you will take a 30 minute boat ride down the Sierpe River and pass through one of the largest mangrove conservations in Central America (which is a RAMSAR site). During the ride, keep an eye out for crocodiles, monkeys, snakes, and water birds. You will continue to the sea through Drake’s Bay until you reach the Caño Island Biological Reserve. The Reserve is considered one of the best dive and snorkel spots in Costa Rica and is home to spectacular schools of fish, coral reefs, manta rays, white tip sharks, dolphins, and whales (depending on the season).

After a morning of snorkeling, you will enjoy a picnic lunch at the beach and then have a choice of either hiking the island trails, seeing the archaeological sites, or snorkeling a little longer.

You will depart the island around 3:00pm and arrive back in Sierpe around 4:30pm, where you will enjoy a cold drink and have a chance to change your clothes and relax a little before the final drive. You will arrive in Dominical around 6:30pm.
