WEST TUCSON. The Arizona-Sonora Desert Museum is one of Tucson's star attractions, with good reason. Part zoo, part natural history museum, and part botanical garden, the facility is set on 21 acres and is home to numerous animals that roam freely within invisibly-fenced enclosures. After checking out the exhibits in the main visitor center, wander along two miles of paved pathways, where you can catch sight of endangered species such as the Mexican wolf, thick-billed parrot, ocelot, margay, jaguarundi, and the Gila topminnow; and not-so-endangered critters like leafcutter ants, black bears, river otters, bighorn sheep, coatis, beavers, coyote, javelinas, black-tailed prairie dogs, termites and roadrunners. And don't miss the captivating cactus garden or the Hummingbird Aviary!

MARANA. One of Tucson's two water parks, Breakers boasts Arizona's largest wave pool, plus five super slides, two tube slides and an entire section set aside especially for little kids. When it's time for a break, huge shade umbrellas and covered ramadas protect guests from the blazing desert sun, and the snack bars offer cold drinks, pizza and other kid-friendly food. No outside food or drink is permitted.

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.

WEST TUCSON. It may seem a bit unorthodox these days to center a museum around a collection of stuffed and preserved animals and insects, but this one actually succeeds. Starting with the holdings of numerous educational institutions and individuals, the curators here have developed an engaging, hands-on learning experience. True, the taxidermists' craft is well represented, but where else can kids (and adults) touch and handle real skulls, fur and skin? And unless you see them up close, it's difficult at best to envision the size and mass of a rhino, a grizzly bear or an elephant. And while you've probably seen "Ice Age" at least once, there are only a handful of places to see a real saber-tooth cat, and this is one of them! Those are some mighty long fangs...

WEST TUCSON. Justin's is the more economical of Tucson's water parks, which is ideal if you're traveling with a posse of young'uns. The park has something for everyone, from a relaxing lazy river to eight giant water slides. Lots of shallow pools cater to the 5-and-under set, but there's also a pool restricted to those 16 and older, so the big kids won't feel too out of place. Justin's has snack bars, but for extra savings you're welcome to bring your own food and non-alcoholic drinks.
