North Coast
EL DUDU

El Dudu is about 15 mins east of Cabrera, you will see a sign on the right side of the road that says : Dudu Lake, drive past this about 1k and stop at the first restaurant on the right to pay the access fee. El Dudu is a classic large cenote type sinkhole, it is about 10 meters down to the water and has very easy access with cement stairs going down to the waters edge.
It is a very popular tourist attraction and local hangout and people are jumping in from all over the place and swimming or getting drunk.
Once geared up it is easier to swim on the surface to the far left side and the beginning of a very large tunnel, this tunnel goes in about 100 meters and has a large air dome at 50 meters in which is a favorite of tour for LDS here. To the right against the wall you will notice an are of breakdown slabs and a warning sign, tie in to the cavern line and go through the restriction you will then get to the cave's mainline which is right in the hallocline.
The first part of the cave features a very large and tall main tunnel that has many dark tannic stained decorations, one column is over 10 meters high' the max depth here is 20 meters. at the end of this tunnel there is a steep slope that goes up to about 6 meters the line here makes a sharp left turn and there is an air pocket with breathable air to the right.
Continuing on the mainline the cave gets lower and you pas through with a series of weird dark stalactites before the tunnel opens up again. The rest of the dive has no decorations and is generally shallower with an average depth of only 6-7 meters.
After swimming about 45 minutes you eventually get to the end of the line which goes up to another entrance called cueva de Lilly, here you will usually see many bats, snakes and the usual cave critters like whip scorpions and tarantulas.
Coming back out you can swim around the cenote to the left and dive the cavern zone which consists of two more tunnels that lead to the third entrance Pozo de los Caballos, before turning back toward the stairs. The cavern zone is quite grandiose and well worth it with huge shellfish encrusted stalactites and very unusual water colors.

The cavern zone was first dove 1993 by Michel Bonin and the main tunnel was first dove to 80m length by Horst Julius in 1995, the main connection to Cueva de Lilly was was made by Bobby Pritchett and Dennis Bourret in 1999.

The cave can be seen with two AL80's and is very large so any configuration will work.
The kids will carry your gear down for a modest fee and the area is very safe for cars and belongings. If you see the kids eating avocados, ask them to get you some, for some reason the ones that grow near El Dudu are the best on the island

This cave is about 1.5 hour East of Sosua/Cabarete which is also 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.

Please check the links section for this area's dive shops, hotels and filling stations
