Trip overview

Trip Overview

Escape to Cocos Island on a liveaboard scuba diving trip in Costa Rica! Cocos is a lush, green, uninhabited island resting 342 miles off Costa Rica's Pacific coast. Rocky pinnacles surrounding Cocos are beacons for big animals and big action. Schooling hammerheads, countless white-tip sharks, mantas, tuna, and even whale sharks call Cocos home. This ten-day trip offers seven days of Costa Rica liveaboard scuba diving.

To get a little insight as to what the trip is like, read the reports from our previous trips: 2015 trip and 2016 trip.
