Six weeks of protests, caravans and a tourism operator work stoppage forced President Claudia Sheinbaum to revoke her own decree reclassifying Loreto as a deep-sea port. The April 10 decree, backed by the Mexican Cruise Association, would have opened the UNESCO-designated Loreto Bay National Park to large-scale cruise traffic. Now a formal working group must write new rules for the bay, and residents say the real fight is just beginning.
Loreto Cruise Ship Decree Triggered a Five-Fold Passenger Surge
Loreto is a town of roughly 20,000 people on the Gulf of California coast in Baja California Sur. Its economy runs on small-scale ecotourism: kayaking, sport fishing and, above all, whale watching in a national park that UNESCO designated a World Heritage Site in 2005. The park covers more than 2,000 square kilometers of islands, coastline and open water.
The Sheinbaum decree reclassified Loreto’s port as a cabotage facility for deep-sea vessels. In practice, that meant larger cruise ships could legally dock or anchor in waters that had been governed, at least on paper, by national park protections. The effects were already visible before the reversal. In the first four months of 2026, more than 7,600 cruise passengers arrived in Loreto. That figure compares to 1,510 for all of 2025.
Residents, fishermen’s cooperatives, tour operators and conservation groups organized quickly. Organizations including Conexiones Climáticas, Conserva Loreto and the Unión de Loreto coordinated a public meeting in a local park. More than 300 people attended. A caravan wound through town with decorated vehicles and honking horns. Then, when what organizers believed was the season’s final cruise ship arrived, hundreds gathered near the marina carrying banners. Many local tourism operators refused to work that day.
Noé Gaona, president of the Union of Cooperatives of Loreto, said many residents initially feared speaking out, worried about repercussions for permits or future work. But the turnout surprised everyone. “It was a genuine movement, a movement that no one expected,” Gaona said.
By late May, Sheinbaum signed a second decree revoking the port reclassification. The new decree cited the area’s “extraordinary biodiversity” and “ecological relevance.” It also created a working group split evenly between government representatives and community or civil society members. That group is now tasked with updating the park’s management plan.
Blue Whale Feeding Grounds Disrupted by Large Vessel Traffic
The stakes of the management plan are tangible. For more than a decade, Loreto’s whale guides have practiced what they call “passive whale watching.” The method, developed and shared among members of the Blue Whale Group of Loreto cooperative, works like this: when guides spot a blue whale’s blow in the distance, they approach slowly to about 100 meters, cut the engine and observe the animal’s behavior before moving closer.
María Nájera, a whale-watching instructor and naturalist, said the technique produces calmer encounters. “We started to realize the whales were much more relaxed,” she said. “They were feeding more easily at the surface.” Tours typically carry groups of six or eight passengers at a time.
Cruise ship visits disrupted that dynamic. Nájera described seeing whales become erratic and abandon feeding areas after large vessels arrived. Areas where guides might regularly observe 10 or 12 whales could fall nearly silent after a cruise ship visit. Blue whales, the largest animals on Earth, are classified as endangered by the International Union for Conservation of Nature. The Gulf of California is one of their key winter feeding grounds.
Gaona questioned the economic tradeoff as well. Most cruise passengers spent little money locally because food and entertainment were included onboard, he said. “We felt we were being pushed aside,” Gaona said. Local guides and fishermen found themselves displaced rather than included, with contracts concentrated among a small number of operators.
Cruise Ships Anchored Inside the Park for 20 Years Under Legal Gray Areas
Advocates say the decree’s reversal alone does not solve the problem. Regi Domingo, a wildlife expedition leader and regenerative tourism advocate based in Loreto, pointed out that cruise ships have anchored irregularly inside the national park for roughly 20 years under legal gray areas. “The revocation of the decree would only bring us back to the same situation we had before,” Domingo said.
The management plan update must include real monitoring, inspections and enforcement to change that pattern, Domingo said. The working group needs to bring together science, local knowledge and government authorities to address both current and emerging pressures on the bay.
Roberto Cerda, a Gulf of California conservation advocate, placed Loreto’s fight in a broader regional context. “Across the Gulf of California, there are simultaneous efforts tied to LNG infrastructure, shipping routes, industrial tourism and even deep-sea mining proposals,” Cerda said. The controversial Saguaro LNG project faces opposition along the Gulf coast. In Topolobampo, Sinaloa, construction of an ammonia plant continues inside a designated Ramsar wetlands reserve despite community backlash. Royal Caribbean’s proposed “Perfect Day” theme park in Mahahual, Quintana Roo, has also drawn resistance.
The working group’s timeline for completing the updated management plan has not been publicly announced. Domingo emphasized that Loreto’s protections cannot function in isolation. “We need to be able to protect the entire Gulf of California as an ecosystem that is all connected,” she said. “It is a corridor for highly migratory species and also for resident species that depend entirely on these ecosystems.” This story was first reported by Mexico News Daily.
