Arizona works well for a family trip if you plan around three things: distance, heat and age limits. The best family stops are spread across the state. A cave, an observatory, a desert zoo and a meteor crater all sit within a day's drive of each other, and several have rules on which children can go on tours.
The prices and rules below are the ones each site published in 2026.
Junior Ranger programmes
Most National Park Service sites run a free Junior Ranger programme. The usual routine:
- Ask at the visitor centre for an activity booklet.
- Work through it during your visit.
- Take the Junior Ranger pledge and collect a badge.
NPS says the programmes are designed for children and their families, but anyone of any age or ability can take part. Badges are usually given only to people who complete the programme in person, so finish the booklet before the visitor centre closes.
Arizona has plenty of parks to collect badges at:
- Grand Canyon: Junior Ranger books and badges are available at the Grand Canyon Conservancy Park Store, across the plaza from the South Rim Visitor Center. It is open daily from 8 a.m. to 6 p.m.
- Petrified Forest: pick up a booklet at the Painted Desert Inn or the Rainbow Forest Museum. The booklet page also lists the Painted Desert Visitor Center, but in November 2026 the park said visitor centre services had moved to the Painted Desert Inn, two miles past the entrance station, during construction. It covers the Late Triassic, when the petrified trees were growing and giant reptiles lived there. Entry is $25 per private vehicle, $20 per motorcycle or $15 per person, and the park takes cards only, no cash.
- Walnut Canyon: Junior Ranger is on the park's list of things to do. The paved Rim Trail (0.7 miles round trip) is easier for small children than the Island Trail, which has 736 stairs.
Arizona-Sonora Desert Museum, Tucson
The Arizona-Sonora Desert Museum, west of Tucson, calls itself a zoo and botanical garden. Its own site could not be read in November 2026, so check current hours and ticket prices at desertmuseum.org before you go.
Lowell Observatory, Flagstaff
Lowell Observatory sits on Mars Hill in Flagstaff at 7,250 feet. It calls itself the "home of Pluto's discovery." It is open Monday and Wednesday to Sunday, noon to 10 p.m., and closed on Tuesdays, Thanksgiving, Christmas Eve, Christmas Day and New Year's Day.
General admission covers guided tours, more than 150 exhibits, the historic buildings, Lowell Universe Theater shows and stargazing. It is valid all day, so you can leave and come back. Keep your sticker or receipt. Telescopes usually open around sunset, which can be as early as 4:30 p.m. in winter. Reservations are not needed for general admission.

Tickets never expire and are non-refundable. Admission includes the guided rim tour, which the operator lists as 35 to 40 minutes. There is also a 4D movie, a discovery centre and a "Blast Zone" for children. Tours of the crater floor are paused while trails are restored.
Kartchner Caverns State Park: the age rules
Kartchner Caverns, near Sierra Vista, is seen only on guided tours. Arizona State Parks strongly encourages booking. You can reserve online or call (877) MY-PARKS and choose option 2, from 8 a.m. to 4:30 p.m. MST.
