About San Ignacio Lagoon Biosphere Reserve

 

Located on the Pacific coast of the Baja California Peninsula, the San Ignacio Lagoon Biosphere Reserve encompasses a critical coastal lagoon and surrounding habitats within Baja California Sur, Mexico. It is recognized internationally for its ecological significance as one of the principal breeding and calving lagoons for the Eastern North Pacific gray whale population. This expansive tidal lagoon, sheltered by sand dunes and desert scrubland, supports a rich diversity of marine and terrestrial life. Beyond gray whales, it provides habitat for sea turtles, migratory birds, and various fish species, contributing to a unique coastal desert ecosystem. The biosphere reserve serves as a crucial stopover point on the Pacific Flyway, attracting thousands of birdwatchers annually. Historically, the lagoon and area have been inhabited and utilized by indigenous communities and are protected under Mexican conservation laws while holding UNESCO Man and the Biosphere Program status. Visitors primarily come to experience guided eco-tours that include whale watching by boat, kayaking, and wildlife photography, with limited infrastructure to preserve its natural state. The reserve promotes sustainable tourism practices, balancing human interest with fragile habitat protection. Its remote location and relatively gentle climate make it a seasonal destination, especially from December through April when gray whales arrive to mate and nurture calves. The stark contrast between desert landscape and thriving marine sanctuary offers unparalleled outdoor experiences for nature lovers and conservation advocates alike.
