WEST TUCSON. Officially called Sentinel Peak, this landmark is visible from all over town. The huge whitewashed "A" on the side of the mountain has been repainted every year since 1915 when ardent U of A fans initially showed their support. Drive to the top for an awesome view of the city and surrounding desert landscape. Tucson's annual Fourth of July fireworks display is launched from here as well.

EAST TUCSON. A 55-acre sanctuary situated right in the city ­ it's not only a haven for wildlife, it's a peaceful retreat for people, too. A mile-long loop trail passes all manner of desert plant life ­ mesquite, desert hackberry, fishhook barrel cactus and catclaw acacia to name a few ­ which harbor a wide variety of birds and other critters like cottontails and gila monsters. If you're planning to stroll through around midday, pack a lunch. The Desert Hummingbird and Butterfly Garden is an especially entertaining spot for a picnic.

CATALINAS. About 20 miles north of downtown Tucson, this popular park offers gorgeous desert vistas and plenty of recreational activities that allow you to take in the scenic beauty of the area. Have a picnic at one of more than 100 picnic areas, hike one of numerous well-groomed trials, or participate in a geological dig. Camping, horseback riding and bird watching are also available.

SOUTHEAST ARIZONA. This dry cave in the Rincon Mountains east of Tucson offers tours that cover the extensive and colorful history of the cave. This tour is particularly popular during the hot summer months, when the cave maintains its cool temperature of 70 degrees, providing a respite from the desert heat. Try a trail ride on horseback, or visit the museum to learn more about the indigenous wildlife, such as bats and ringtailed cats. A butterfly garden and desert tortoise exhibit are other offerings. Reservations are suggested for the guided trail rides, which leave from La Posta Quemada Ranch.

SOUTHEAST ARIZONA. Although discovered by two amateur cavers in 1974, the existence of Kartchner Caverns was not commonly known until 1988 when the state purchased the caves and surrounding land for use as a public park. Guided tours last about 1 ½ hours, and lead guests past some of the most amazing and colorful cave formations in the world. The Rotunda/Throne Room tour is offered daily, year round; Big Room tours are offered daily, October 15 ­ April 15, but due to the difficult terrain of this tour, children under 7 are not permitted. The park also features hiking trails, a Discovery Center and 62 campsites.
