Hidden Caves Mapped in Playa del Carmen’s Marsella IV Site

Playa del Carmen, Mexico — The citizen science project Cenotes Urbanos has successfully mapped two caves located in the area where the fourth phase of the Marsella housing development is set to be constructed in western Playa del Carmen. The discovery was reported by the Facebook page Playa Difunde, citing Alejandra Flores, a volunteer with the environmental collective.

Advanced Equipment Enables Precise Mapping

According to Flores, the exploration and mapping were made possible by recently acquired advanced equipment, funded through a donation. This technology allowed for more accurate measurements of the water quality in the underground caves, which are situated in the northern part of the city near the landfill and the Maya Train route.

“The goal is to have a record of the current conditions before construction begins, so we can later assess the impact on the underground water systems,” Flores explained.

Cleanup Initiative Planned Amid Pollution Concerns

Flores also announced that a cleanup effort is being organized for the area, scheduled for either this or next Sunday. The initiative aims to remove waste allegedly dumped by nearby food businesses, which poses a risk to the aquifer systems below.

This effort is part of a broader campaign by Cenotes Urbanos, which has mapped over 130 caves, caverns, and cenotes within Playa del Carmen’s urban sprawl to raise awareness about protecting these unique ecosystems.

Details of the Marsella IV Project

In November 2024, Mexico’s Secretariat of Environment and Natural Resources (Semarnat) approved the Marsella IV development, spearheaded by the company Industrias Curator. The project includes the construction of 1,019 single-family homes on a 26-hectare plot between Lilis and Flor de Ciruelo avenues.

The development involves a land-use change to clear 22.88 hectares of recovering medium subperennial jungle, an area identified as a growth hub in Playa del Carmen’s Urban Development Plan. Construction is expected to begin in the coming weeks after nearly two years of federal environmental permitting.

Why This Matters

The Riviera Maya sits atop an interconnected system of caves and underground rivers. Unmonitored disruption of these ecosystems could lead to irreversible environmental damage and threaten the region’s water security. Organizations like Cenotes Urbanos urge urban planners to incorporate these maps and water quality data into sustainable development strategies before further housing projects proceed.
