The 3 Eyes National Park (Los Tres Ojos, Santo Domingo) — Limestone Cave Lagoons Walk + 4th Open-Air Lagoon Barge (Protected Area Visit; Tickets via Official Platform)

Los Tres Ojos National Park is a natural limestone-cave attraction just east of Santo Domingo, where you descend via stairways into caverns and follow pathways around three freshwater blue lagoons (“eyes”). A fourth lagoon can be reached via a small wooden barge, opening up to an outdoor scene with lush vegetation; keep an eye out for petroglyphs and pottery shards.

• Access to the Los Tres Ojos protected-area visitor route (caves + lagoon viewpoints; self-guided on marked paths).

• Perfect for: nature lovers, photographers, families, first-time Santo Domingo visitors.
• Not ideal if you struggle with lots of stairs (the main access is via stairways down into the caves).

• Walk the park’s internal paths around the three lagoons, then (optionally) cross by wooden barge to the fourth lagoon area for more viewpoints.

• Tickets / price (official): the Ministry of Environment implemented digital entry charging here as a pilot and directs protected-area visitation through its official platform. Check the official “Visitas a las Áreas Protegidas” channel for current fees and entry rules.
• Opening hours (official): not published on the official tourism page I could access; verify current hours in the official protected-area visitation channel before you go.

• Time needed: 1—2 hours for a relaxed visit (more if you take lots of photos).
• Wear non-slip shoes (humid stone paths + stairs).

Santo Domingo’s famous “three lagoons in limestone caves” park, plus a 4th lagoon reached by wooden barge. Fees/hours should be checked on the official protected-areas visitation platform.
