The Baja California Peninsula is one of the most special places in the world. Surrounded by the Pacific Ocean on the west and the Sea of Cortés on the east, this 775-mile-long peninsula has a warm climate and diverse terrain, ranging from coastal sand dunes and rugged mountain peaks to desert flats to isolated islands. The varied landscape supports an amazing diversity of plant and animal life—towering cardón cacti, islands crowded with breeding birds, and insects and arachnids with special adaptations to cope with life in the dunes.
The peninsula has been a magnet for adventurers and naturalists, including our own researchers who have been exploring and studying the region for more than a century. Go on an expedition with our scientists as they work alongside colleagues in Mexico to conserve one of the most amazing places on earth.
Using specimens from the Museum’s scientific collections alongside immersive imagery and stories about conservation work happening there, Expedition Baja brings to life one of the most incredible regions in the world.
At home in a brand-new gallery on the top floor of the Museum, this new permanent exhibition takes visitors off the beaten path on a journey with researchers through sky and sea islands, palm oases, and fog deserts as they discover new species, work to conserve native plants and animals, and explore the most remote parts of the peninsula.
In keeping with the Museum’s binational focus, all information in Expedition Baja is presented in both English and Spanish.
Southern California and the Baja California Peninsula are linked together by more than a name. Whether you're an educator, student, or just want to learn more about our neighbors in nature, you can find educational resources, talks, quick facts, and more through our learning resources.
Binational collaboration is key to the future of the Baja California Peninsula. We thank the conservation community that is collectively protecting this region.
