Into the heart of the Sonoran Desert:
So your conference in Tucson is over and you're staying over until Sunday to get the cheap Saturday-stay airfare. What's there to do with a day or two to spare? More than you'd think.
As anyone will tell you, there are two absolute must-see attractions in Tucson-Saguaro National Park and the Arizona-Sonora Desert Museum. Luckily these two attractions are pretty much side by side, which makes it easy to visit them both in a single day. Together these two attractions on the west side of Tucson are a superb introduction to the Sonoran Desert (By the way, the national park actually has an east unit as well.) The Sonoran Desert, home to the massive saguaro, the west's most recognizable species of cactus, is one of the wettest and greenest deserts in the world, but nonetheless, it's still a desert. In the national park you'll see forests of massive saguaros, and at the museum (actually more zoo than museum), you can learn all about the myriad plants and animals that inhabit this desert.
