1 Best Sight in Palm Springs and the Desert Resorts, California

In 1938, Chester "Cactus Slim" Moorten, an original Keystone Cop, and his wife, Patricia, opened this showplace for desert plants—now numbering in the thousands—that include an ocotillo, a massive elephant tree, and a boojum tree. Be sure to stroll through the Cactarium, the world's first as the Moortens coined the term, to spot rare finds such as the welwitschia, which originated in southwestern Africa's Namib Desert.
