The dive

El Pantano ('the swamp') is named for the colour of the entry, but it is a sinkhole: behind the restrictions lies a pronounced halocline and then crystal-clear water.

Profile and sections

El Pantano ('the swamp') is named for the colour of the entry, but it is a sinkhole: behind the restrictions lies a pronounced halocline and then crystal-clear water. The rock is soft and crumbly; side passages and restrictions carry a collapse risk.

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

Ten minutes' walk past El Árbol, due east. Park in front of the landowner's house and pay (or buy his lemons). Gear up in the mud, wade or crawl until it gets deeper.

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.
