Saguaro National Park
The Saguaro cactus is perhaps the most endearing symbol of the Sonoran Desert and the American southwest. Among the best places to see these marvels of nature up close is the 92,000-acre Saguaro National Park. There are two sections of the park: east (the Rincon Mountain District) and west (the Tucson Mountain District). President Herbert Hoover in 1933 used the Antiquities Act to establish the Saguaro National Monument, and President John. F. Kennedy added the Tucson Mountain District in 1961. In 1994, Congress combined the two districts to form the national park. Today, in addition to the stunning views, there are 165 miles of trails for visitors to explore.
