San Ignacio Lagoon is one of the last intact gray whale nurseries in the world, and it stays that way because the people who live and work on it have agreed to limit what happens there.

This page explains how the lagoon is protected, what the local operators hold themselves to, and what your visit actually contributes.

What Is San Ignacio Lagoon?

San Ignacio Lagoon, also known as Laguna San Ignacio, is a shallow coastal lagoon on the Pacific side of Baja California Sur, Mexico. It has a narrow ocean entrance, broad protected basins, and mangrove edges.

Gray whales are generally present from mid-January through mid-April, when females give birth and raise their calves in the lagoon’s sheltered water before the long migration north. Baja Ecotours schedules most Campo Cortez trips from early February through late March.

It is also one of the few places on earth where wild gray whales sometimes choose to approach small boats and stay alongside them.

The lagoon matters outside whale season too. Its mangroves shelter young fish, its tidal flats feed migratory shorebirds, and the fishing families around it have worked these waters for generations.

How Is the Lagoon Protected?

Two designations sit over San Ignacio Lagoon:

El Vizcaíno Biosphere Reserve, established in 1988, which places the lagoon inside one of the largest protected areas in Latin America.
UNESCO World Heritage listing in 1993, as part of the Whale Sanctuary of El Vizcaíno.

Whale watching inside the lagoon is not open to anyone with a boat. It happens within a designated observation area, and only operators holding the required permits and authorizations may work there.

Baja Ecotours arranges the permits and authorizations its excursions require. Guests do not need to apply for anything themselves, and no one should be asking you to buy a whale-watching permit on arrival.

What Do the Local Operators Hold Themselves To?

The whale-watching operators at San Ignacio Lagoon belong to a local association, Laguna Baja ARIC, founded in 2000. Maldo Fischer, co-founder of Baja Ecotours, helped establish it and still supports it.

ARIC exists because the operators wanted stricter limits than the general Mexican rules require. Mexican regulation permits up to four boats around a single whale. ARIC holds its members to two.

The practices its members follow include:

No more than 16 authorized pangas inside the observation area at one time
Up to approximately 90 minutes in the observation area for each excursion
No more than two pangas around an individual whale, with the second waiting its turn rather than crowding the animal
Spreading boats through the area when possible
No chasing, surrounding, blocking, or forcing whales to approach
Letting the whale decide whether a close encounter happens, how close it comes, and when it leaves

The lagoon issues a limited number of whale-watching permits each season. Twenty-seven are held across all operators, and Baja Ecotours holds four of them.

Why Does the Two-Boat Rule Matter?

A whale that approaches a panga is doing something entirely voluntary. It has not been trained, fed, or rewarded, and nothing obliges it to come.

The quickest way to lose that behavior is to surround the animal. A whale hemmed in by boats stops choosing to approach them.

Holding the limit at two boats, with the second hanging back and waiting, is what keeps the encounter on the whale’s terms. It costs the operators time on the water, which is exactly why it has to be an agreement rather than a preference.

Who Benefits from Whale Watching Here?

Campo Cortez is a family-run ecolodge on the edge of the lagoon, built and operated with the Fischer family. Its captains, camp team, and many of its guides live in the San Ignacio Lagoon region, and several come from fishing families with long histories on this water.

Baja Ecotours has been bringing guests to the lagoon since 1989. The camp takes approximately 24 to 26 guests at a time, and each panga carries no more than eight.

That scale is deliberate. It keeps the pressure on the lagoon low, and it keeps the work and the income local rather than routed somewhere else.

At camp, the operation works to limit its own footprint by conserving water, reducing waste, recycling where possible, and leaving nothing behind on the water or the shoreline.

What Can I Do as a Visitor?

The most useful thing a visitor does is choose an authorized operator and then follow the people running the boat.

Do what the captain and guide ask, straight away, particularly when a whale is close
Stay seated while the panga is moving and ask before standing or changing position
Do not reach for, grab, feed, or try to hold a whale, and keep away from its eyes, blowhole, and mouth
Let the whale end the encounter when it decides to
Take your rubbish back to camp, and keep single-use plastic out of the boat
Pay the Vizcaíno Biosphere Reserve entrance fee, which goes toward the protected area itself

Swimming with the gray whales is not part of any Baja Ecotours excursion.

None of this is complicated, and it is the difference between a lagoon that still has friendly whales in twenty years and one that does not.

Plan a Trip to the Lagoon

Campo Cortez takes a small number of guests at a time and the season is short, so the most popular February and March departures fill early.

Maldo Fischer Contributing Expert

Maldo Fischer is the co-founder of Baja Ecotours and one of the most experienced local whale-watching guides at San Ignacio Lagoon. A lifelong fisherman, conservation advocate, and lagoon resident, Maldo has spent more than 35 years introducing guests to the gray whales of San Ignacio Lagoon and helping shape the respectful whale-watching practices that Baja Ecotours follows today.

Together with his wife, Katalina, Maldo built Campo Cortez as a family-run ecolodge rooted in the history, traditions, and natural rhythms of San Ignacio Lagoon. Katalina is the niece of Francisco “Pachico” Mayoral, the local fisherman widely recognized as the first person to have a friendly encounter with a gray whale in San Ignacio Lagoon. Through this family connection, Campo Cortez and Baja Ecotours are tied to the very beginning of the “friendly whale” story.

As tourism grew at San Ignacio Lagoon, Maldo became a leading voice for responsible whale watching. He helped found and continues to support ARIC, the local association that established community guidelines for whale-watching operators in the lagoon, created to prevent overcrowding, reduce pressure on the whales, and encourage respectful boat practices that allow whales to approach naturally. Maldo and the Fischer family are also featured in The Lagoon by James Dorsey, a book exploring the people, whales, and history of San Ignacio Lagoon.
