Dating to the 1920s, this legendary hostelry is located on 70 acres at the Oasis of Mara, just a stone's throw from the primary visitor center for the park. The inn is home to several artesian-fed ponds, not to mention the actual 29 palm trees for which the surrounding town is named. Rooms and guest houses each have their own unique décor and shape. I especially like the Bottle Room, with bottles built into the walls, and Irene's Historic Adobe, a standalone adobe that sleeps up to 4 people. The pool is a perfect respite from the desert heat, and the restaurant is one of the best in the area, sourcing a good deal of produce form gardens onsite.
