The desert garden is a must. It has one of the richest succulents in any place I have seen. Think of the many described cacti, cacti, Cylindropuntias, Echinocereus, Echinopsis, Euphorbias, and agave; you will find them there. There are also many trails for you to explore, which will enhance your tour experience. This is a video of some highlights from my last visit.
