Entry and exit can be difficult when diving Asan Cut from shore, it is recommended that divers unfamiliar with this site only attempt a dive here with a buddy experienced with this location. Either way this dive should not be attempted during a tide change or when surface waves are present, as there will likely be a strong rip current.
The cut itself is littered with coral and rock columns, which can be very disorientating to navigate even when familiar with the site. In the event, you need to surface away from your dive float remember to deploy a DSMB.
Visibility at the entry and exit point is usually pretty poor, but don’t be discouraged as it usually opens up quite a bit once you get through the cut. The remains of an amtrak from the U.S. invasion during World War II can be found toward the north-east in about 25 feet of water. Visibility tends to be better to the north-west. Asan Cut is a great dive and offers an abundance of marine life, including sharks, rays, octopus, and even the occasional pod of dolphins.
