At Sian Ka’an Biosphere Reserve, Tourist Center Project Faces Opposition

Military Construction Moves Forward at UNESCO-Protected Reserve

The Mexican military is building a major tourist complex in the Sian Ka’an Biosphere Reserve without required environmental permits, drawing fierce opposition from local communities and environmental advocates who fear the project threatens one of the world’s most important protected wetlands.

The “Puerta al Mar” (Gateway to the Sea) project represents part of a broader infrastructure push linked to the Maya Train railway. With an estimated cost of 175 billion pesos (approximately $9.7 billion), the development calls for a 54.6-kilometer (34-mile) paved road cutting through sensitive wetlands from Felipe Carrillo Puerto to the Caribbean coast.

The ambitious plan includes construction of restaurants, commercial parking areas, pedestrian walkways, and a pier with observation deck. Most controversially, the military intends to create an artificial beach spanning 6,000 square meters (1.5 acres) complete with palapas and lounge chairs where mangroves currently stand in Vigía Chico.

“The capacity for boat traffic in Sian Ka’an is already at its limit — you can’t add more,” said Víctor, a local lobster fisherman interviewed by Animal Político, reflecting concerns shared throughout the coastal community of Punta Allen.

Sacred Territory Under Pressure

Sian Ka’an, whose name means “where the sky is born” in Yucatec Maya, has been federally protected since 1986 and became a UNESCO World Heritage Site one year later. The reserve encompasses 528,000 hectares (1.3 million acres) of tropical forests, mangroves, marshes and marine areas that support over 300 bird species, jaguars, manatees and part of the Mesoamerican Reef System.

The construction began in August 2023 following an official groundbreaking ceremony, despite lacking environmental impact studies or public consultation with local communities. Mexico’s Ministry of National Defense (Sedena) leads the project with support from Quintana Roo state agencies.

Quintana Roo Governor Mara Lezama defends the project as fulfilling “an old and legitimate demand” from residents of Felipe Carrillo Puerto, who she says deserve coastal access for recreation and tourism development. However, many locals question whether the military is truly building for community benefit.

Maya activist Ángel Sulub told El Universal that Puerta al Mar represents “dispossession from the Maya community” of traditional use rights to what they consider a sacred pathway through the jungle.

Environmental and Economic Fears

Local opposition extends beyond cultural concerns to practical worries about ecosystem damage and economic disruption. Lobster fishermen fear increased boat traffic will harm marine species and potentially lead to theft of their traps, which provide crucial family income.

Tourism workers in Punta Allen, a village that has carefully balanced eco-tourism with conservation for decades, worry the military project will bring environmental destruction they’ve worked to avoid.

“Here we have great environmental awareness, and the devastation of the jungle and wetlands concerns us,” said one longtime resident who requested anonymity, citing fear of military retaliation. “It also worries me that this is a military project, because people are afraid of soldiers and will stay quiet even if they don’t approve.”

The project’s environmental impact assessment remains under government review, with officials describing the massive infrastructure development as having “low impact” on the protected ecosystem. Critics note the assessment provides no details about how an artificial beach will be created or where sand will be sourced.

Construction Stalled Amid Legal Challenges

Work on Puerta al Mar came to a halt in November 2024 when ejidatarios (communal land holders) from Felipe Carrillo Puerto blocked construction sites. Both Governor Lezama and Felipe Carrillo Puerto Mayor Mary Hernández have promised to restart construction, but work remains suspended.

Local reports suggest budget constraints may be hampering the project’s progress, though officials have not confirmed funding issues.

The controversy reflects broader tensions over mega-development projects in Mexico’s protected areas. National Geographic recently documented extensive cenote damage from Maya Train construction, highlighting ongoing conflicts between infrastructure development and environmental protection.

Sedena’s expanded role in tourism development represents a significant shift from traditional military functions. The armed forces now operate hotels, manage archaeological sites, and oversee major infrastructure projects across southeastern Mexico.

Regional Development Debate

The Puerta al Mar project exemplifies challenges facing Mexico’s protected areas, which have experienced significant budget cuts while new protected territories are being designated. Environmental agencies struggle to monitor and enforce protections across the country’s 225 protected areas.

For fishing communities like Punta Allen, the military development threatens a delicate balance achieved over decades. The village has successfully developed sustainable tourism while maintaining traditional fishing practices and protecting the reserve’s ecological integrity.

“I wonder who this road is really for and who will truly benefit,” said Esquivel Pat from the U Kúuchil K Chi’i’bal Community Center in Felipe Carrillo Puerto, echoing concerns voiced throughout the region.

Community defender Wilma, who has bicycled the old dirt road to Vigía Chico her entire life, fears the paved highway will open Sian Ka’an to additional mega-tourism projects that could permanently alter the protected landscape.

As Mexico balances development pressures with conservation commitments, the Sian Ka’an controversy may signal broader challenges ahead for the country’s most treasured natural areas. The outcome could set important precedents for military involvement in protected territory development and the role of local communities in decision-making processes.

The project’s future remains uncertain as legal challenges, community opposition, and potential funding constraints continue to stall construction in one of Mexico’s most biodiverse and culturally significant landscapes.
