EL PUERTO SEA CAVES

About 5 mins west of Cabrera there is a small fishing beach called El Puerto. There is a very weird reef which is a huge ancient limestone sinkhole just about 150 meters to the east in front of the point. Standing on the beach you can make out the contours of the drop off looking to the east. It is an ocean dive like no other on par with any good cave dive, for most of the dive you are in fact in the reef as it is riddled with tunnels and caves, not really a cave dive per say, but an epic dive nonetheless.
It is as good as an ocean dive can get and blends cave diving with ocean diving in one. It is one of if not the best ocean dives I have ever done anywhere in the world and well worth it. The tunnels range from huge and wide to SM only and the rock looks otherworldly everywhere like you are diving in the intestines of a whale or something along that line. There are many small tight tunnels that then open up inside the reef and turn into closed little reef systems full of all kind of fish and critters. It is 15 meters to the bottom but all the caves and tunnels are very shallow at an average depth of 4-7 meters.

It will take a few dives to see the entire site, but we usually do the dive with two AL80's, due to the depth this will allow for very long dives. Although you can swim from the beach and dive, it is way better to rent a fishing boat from the local fishermen, that way you don't have to swim back and can dive way further out.

This site is about 1.5 hour East of Sosua/Cabarete which is the closest filling station.

There is a really good restaurant in Rio San Juan called La Casona, every time we dive this area we eat there, in fact it's the only good restaurant in the entire area.
