Mexico’s environmental ministry has denied approval for Royal Caribbean’s massive “Perfect Day Mexico” project in Mahahual, bringing a dramatic end to a development that had drawn fierce public opposition over its potential impact on one of the Caribbean’s most ecologically sensitive coastlines.
Semarnat Secretary Alicia Bárcena announced the decision Tuesday at a Mexico City press conference, saying it was final. “No se va a aprobar el proyecto Perfect Day de Royal Caribbean,” she said — the project will not be approved. She added that the company itself had also been moving toward withdrawing the application, though the agency’s rejection stands regardless.
Hours later, Royal Caribbean issued a measured but downbeat response. “We are disappointed by Semarnat’s decision and respect the role of Mexico’s environmental authorities,” the company said in a statement. “Mahahual is a special place that deserves care and protection.” The cruise line said it remains committed to Mexico and plans to open a dialogue with stakeholders in the coming weeks about what it called “shared prosperity.”
A Village vs. a Megaproject
Mahahual is a fishing village of roughly 2,600 people on Quintana Roo’s southern Caribbean coast — also known as the Costa Maya — that hosts more than 550 cruise ships a year. Royal Caribbean purchased the port there in July 2025 and quickly unveiled plans for a 230-acre private destination modeled on its existing Perfect Day resorts in the Bahamas and elsewhere.
The scope of the project stunned many observers. Plans called for more than 30 waterslides, 12 restaurants, 24 bars, and what was billed as the world’s largest sombrero — all of it requiring the clearing of more than 90 hectares of jungle and mangrove. The company projected up to 20,000 visitors per day and promised 4,000 direct jobs during construction and operations. Royal Caribbean had committed approximately US$292 million to acquire the port and surrounding land, with an additional US$529 million earmarked for construction, for a total investment of roughly US$821 million.

A Reef at Stake
Environmental groups had been sounding alarms for months. Mahahual sits adjacent to the Mesoamerican Reef — the world’s second-largest barrier reef system — and critics argued the construction would destroy mangroves essential for water filtration and coastal protection, disrupt the regional aquifer, and threaten species including jaguars and sea turtles.
In January, a Quintana Roo district court issued a halt order following an injunction filed by the environmental organization Right to a Healthy Environment (DMAS). Work eventually resumed, but opposition kept building. A Change.org petition against the project accumulated more than 4.4 million signatures. Greenpeace hung a banner outside Mexico City’s Palacio de Bellas Artes warning of an “environmental tragedy.”
The day before Bárcena’s announcement, President Claudia Sheinbaum weighed in publicly. “We must not do anything that affects that area, which has a very important ecological balance, and is particularly important for the reefs,” she said. She suggested the project could potentially be relocated to a less sensitive part of Quintana Roo — an offer Royal Caribbean left open in its statement, saying it looks forward to talks in the weeks ahead.
Investors Take Note
The market wasn’t thrilled. Royal Caribbean shares fell for a third straight session Tuesday, closing at US$247 on the New York Stock Exchange — the lowest level since mid-November. The company, headed by CEO Jason Liberty, had framed Perfect Day Mexico as a cornerstone of its Caribbean expansion strategy.
Royal Caribbean acknowledged in its statement that it still believes in Mexico’s potential. “We remain optimistic about the prospect of moving forward with our responsible investment,” the company said, without specifying any new locations or timelines.
