With its 18th-century Spanish colonial architecture and laid-back local scene, San Jose del Cabo provides a low-key Baja Peninsula counterpart to fun-loving Cabo San Lucas 20 miles south. Scuba dive and kayak in Cabo Pulmo Marine Park, home to the Sea of Cortez's only hard coral reef and the wreck of the fishing boat Colima. Visit the 200 bird species that live in the tranquil San Jose's Estuary and Bird Sanctuary. Sunbathers will fall in love with Playa Palmilla, one of Mexico's best beaches.
