This well-restored mission is between Rosarito and Bahía de los Angeles in pristine, spectacular boojum tree-and-cardón desert. The drive alone (though bumpy) makes it worth the trip. A family descended from the original preconquest inhabitants is restoring it by hand and will proudly show you the mission, a freshwater spring, a secret tunnel (now walled up, shucks!) and the old Jesuit ruins. Heading east from Hwy 1, turn right about 45km after leaving the highway.
