About this site
Big Channel lies in the waters off San Andrés, the Colombian island in the western Caribbean that sits within the San Andrés, Providencia and Santa Catalina archipelago. Dive operators on the island typically run boat trips out to sites along its surrounding reef system and channels from town. The site is rated technical, setting it apart from the more casual reef dives found closer to shore.
