It's impossible to come check out Anza-Borrego without a visit to the Natural History Association. Here is where you can learn everything about the plants, wildlife, and Laguna mountains surrounding the desert.
If you are interested in any of the plant or wildlife tours, this is also the place to come and see what is going on when you visit. Better yet-,check it out before visiting so you can time your visit with a unique activity.
There is also a small store here where you can find maps, jewelry, and handmade greeting cards by local artists. During the wildflower blooming season, they usually have booths out where you can sample teas from local plants, samples of plants used to color fibers, and live demonstrations of native pottery making.
