The dive

Cueva Negra is richly decorated throughout, but tannin has stained its formations dark, which makes it a very dark cave. Dive Dominicana calls it a challenging system of narrow passages and complex geology, for experienced divers.

Very silty: percolation often takes away the visibility in parts of the cave.

This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.

How to get there

In Cotubanamá national park (which the DRSS still calls Parque del Este), about 3 km north-east of Sistema El Cangrejo: as there, by boat only and then a hike through the jungle. The main entrance is a large sinkhole with fairly easy access. On request with Dive Dominicana, price on enquiry.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (DRSS dr-ss.com, Dive Dominicana, Dominican Divers, Scuba Diving, Advanced Diver, World Nomads, divemasteraustin.com, showcaves.com, godominicanrepublic.com, Dominican press, DAN; Oct 2026), the book Las cuevas sumergidas de República Dominicana (environment ministry / Fundación Espeleobuceo Hispaniola, 2003; facts only); Dive Dominicana's gases and prices confirmed by Dive Dominicana, and Golden Arrow's details by Golden Arrow (Oct 2026). Oleg's Bat House and Sistema La Negra were added in Nov 2026 (DRSS, Dive Dominicana, Dominican Divers, and for Oleg's Bat House Caving News and DR1 after Listín Diario, 2011). The DRSS descriptions date from around 2013. Pins only where a source gives them; the caves on private land around Santo Domingo deliberately without a pin.
