The Islas de la Bahía de los Ángeles Biosphere Reserve is a protected marine and island area known for its unique desert island ecosystems, rich marine biodiversity, and outstanding opportunities for wildlife viewing and water-based recreation.
Located in the Gulf of California off the northeastern coast of Baja California, Mexico, the Islas de la Bahía de los Ángeles Biosphere Reserve encompasses numerous islands and surrounding marine habitats in the Bay of Los Angeles. This reserve protects a remarkable mix of desert island landscapes, pristine beaches, rocky shorelines, and vibrant marine ecosystems including coral reefs, kelp forests, and seagrass beds. The islands provide critical breeding grounds for seabirds, sea lions, and endangered species such as the totoaba fish and the vaquita porpoise, one of the world's rarest marine mammals. Terrestrial flora features drought-adapted cacti, scrub, and desert succulents unique to the islands’ arid climate. Historically, the islands supported fishing communities and were visited by indigenous groups; today, the reserve balances conservation with sustainable ecotourism. Visitors are drawn to activities such as snorkeling, scuba diving, kayaking, wildlife watching, and sport fishing. Notable landmarks include Isla Coronado with its volcanic cliffs and diverse sea lion colonies, and Isla Montserrat, known for its bird nesting sites. The reserve serves as both a natural laboratory and a haven for outdoor adventure, offering visitors unspoiled scenery and close encounters with rare wildlife. Strict access regulations ensure minimal human impact, preserving the area’s ecological integrity while supporting responsible recreation and environmental education.
