Flagstaff is one of those rare destinations where kids stay just as excited as their parents. The mix of national monuments, hands-on museums, world-class observatories, and easy mountain trails means a single trip can feel like five different vacations. The hardest part is choosing what to skip.
This guide highlights eight family activities Flagstaff visitors come back for year after year, with practical detail under each one. You’ll find a quick reference table to plan your days, real notes on cost and difficulty, and links to the official sources that maintain each site so you can verify hours and seasonal access before you go. The eight adventures below were chosen for one simple reason: each one delivers a genuinely memorable experience for kids without sacrificing what the adults in the group want from a Flagstaff family fun trip.
Why Flagstaff Works for Family Travel
The city sits at nearly 7,000 feet elevation in the world’s largest contiguous ponderosa pine forest. That setting matters for families because the air is cooler, the landscape is varied, and almost every major attraction is within a thirty-minute drive of downtown. Add in dark night skies, accessible trails, and a strong network of museums and monuments protected by the National Park Service, and you have an unusually concentrated set of options for travelers with kids.
Each of the eight adventures below covers a different kind of experience, from underground lava tubes to historic mansions and rooftop telescopes. Mix and match based on your kids’ ages, your group’s energy, and the weather forecast.

The 8 Must-Visit Family Adventures
1. Stargaze at Lowell Observatory
Lowell Observatory is the world-famous research site where Pluto was discovered in 1930. Today, it’s also one of the best things to do with kids Flagstaff offers. Daytime visits include guided tours, exhibits, and the Marley Foundation Astronomy Discovery Center. After dark, families can look through six advanced telescopes at the Giovale Open Deck Observatory or take in a rooftop Dark Sky Planetarium show. Educators are on hand to help younger kids understand what they’re seeing.
Flagstaff has been the world’s first International Dark Sky City since 2001, so the sky over Lowell is unusually clear. Buy tickets online during peak weeks. For full pricing, hours, and program details, see Lowell Observatory’s official experiences page.
2. Walk Among Cliff Dwellings at Walnut Canyon
Walnut Canyon National Monument preserves 25 cliff dwellings built by the Sinagua people roughly 800 years ago. The Island Trail descends 185 feet into the canyon and lets kids walk past the actual rooms. The Rim Trail is a flatter alternative for younger children, strollers, or anyone managing the altitude. The walk takes about an hour at a relaxed pace, and the visitor center has hands-on exhibits and a short film.
For current hours, fees, and trail closures, check Walnut Canyon National Monument on the National Park Service site.
3. Hike a Lava Field at Sunset Crater Volcano
Sunset Crater erupted around 1085 CE and is the youngest cinder cone in the San Francisco Volcanic Field. The 1-mile self-guided Lava Flow Trail loops through a black, rocky landscape that looks like nowhere else in Arizona. Kids tend to love the contrast between black lava rocks and tall ponderosa pines that have grown back over the centuries. Hiking on the cinder cone itself is not allowed, but the trails at the base are accessible for most ages.
For visitor center hours and trail status, see Sunset Crater Volcano National Monument’s official page.
4. Explore Ancient Pueblos at Wupatki
Wupatki sits north of Sunset Crater on the same scenic loop road, and the two are designed to be visited together. The site preserves over 2,600 ancestral Puebloan structures, including the namesake Wupatki Pueblo, a multi-story red sandstone village with a ballcourt and a natural blowhole. Kids who liked Walnut Canyon usually love Wupatki even more because the buildings are above-ground and easier to imagine living in.
The drive between Sunset Crater and Wupatki is itself a highlight, with painted-desert views opening up between the two visitor centers. See Wupatki National Monument’s NPS page for current information.
5. Spend a Morning at the Museum of Northern Arizona
The Museum of Northern Arizona (MNA) is a nationally awarded institution focused on the cultures and natural history of the Colorado Plateau. Kids gravitate to the life-size Dilophosaurus dinosaur skeleton in the lobby and the rotating exhibits in the Discovery Room. The museum’s family guide outlines activity kits, scavenger hunts, and a Junior Paleontologist program designed for younger visitors.
MNA also has picnic tables outside, a Rio de Flag nature trail, and a small playground a short walk away. For current exhibits, ticketing, and family-specific programming, see the Museum of Northern Arizona family guide.
6. Roam the Trails at the Arboretum at Flagstaff
The Arboretum is a 200-acre conservation site at 7,150 feet, surrounded by ponderosa pine and looking out at the San Francisco Peaks. It’s home to over 750 plant species native to the Colorado Plateau, plus gardens, greenhouses, a butterfly area, and several short loop trails kids can comfortably handle. The Arboretum runs daily raptor programs, summer camps, bird walks, and wildflower talks during the season.
Plan ahead for the dirt access road, which can be rough in a sedan. Confirm seasonal hours and current programming at The Arboretum at Flagstaff.
Hands-on museum exhibits give kids a way into the region’s history and natural science that no guidebook can match.
7. Explore Underground at Lava River Cave
Lava River Cave is a roughly mile-long lava tube formed about 700,000 years ago when molten rock erupted from a volcanic vent at Hart Prairie. It’s the longest cave of its kind in Arizona and surprisingly accessible. Inside, temperatures hover around 42°F year-round, so warm clothing is essential. Bring at least two reliable flashlights per person and sturdy shoes with grip. Kids who can handle a little uneven walking find the cave thrilling.
The cave is managed by the Coconino National Forest and is free to visit. For driving directions, conditions, and safety information, see Lava River Cave on Recreation.gov.
8. Step Back in Time at Riordan Mansion
Riordan Mansion is a 13,000-square-foot Arts and Crafts duplex built in 1904 by two brothers who ran one of the largest lumber operations in the territorial Southwest. Guided tours of the East House run hourly and last about an hour. Kids find the toy room, vintage Edison phonograph, and original Stickley furniture genuinely interesting once a knowledgeable docent puts the rooms in context. Park grounds are picnic-friendly and offer space for younger kids to stretch their legs before or after the tour.
Tours fill up during summer weekends. Reserve in advance through Riordan Mansion State Historic Park on Arizona State Parks.
Flagstaff family fun is rarely loud. The best memories often come from quiet moments outside.
Practical Family Tips for Flagstaff
A few small habits make a big difference once you’re on the ground.
- Hydrate from the start. Most family altitude headaches come from skipping water on travel day. Aim for two to three liters per adult, more for active kids.
- Plan outdoor activities for the morning. Summer afternoon thunderstorms are common in northern Arizona’s monsoon season. Check the National Weather Service Flagstaff forecast before each day.
- Stack monuments smartly. Sunset Crater and Wupatki sit on a single 35-mile scenic loop. Walnut Canyon is on the way back from a Grand Canyon day. Plan geographies, not just attractions.
- Pack layers, always. Mornings at 7,000 feet can start in the 40s and warm into the 80s by midday.
- Carry the America the Beautiful pass. It covers all the NPS-managed monuments on this list and saves time at every entrance.

Late May through early October is the sweet spot for outdoor family activities. Trails are dry, the monsoon afternoon storms typically pass quickly, and most family-friendly sites including the Arboretum operate full schedules. Winter is wonderful for snow play but limits some of the outdoor adventures on this list. Spring and fall offer the lowest crowds and very comfortable temperatures.
Are these family activities Flagstaff sites stroller and wheelchair accessible?
Many are. Lowell Observatory, the Museum of Northern Arizona, Riordan Mansion grounds, and the Sunset Crater Lava Flow Trail are largely accessible. Walnut Canyon’s Rim Trail works for strollers, while the Island Trail does not. Lava River Cave requires walking over uneven volcanic rock and is not stroller-friendly. Check each site’s accessibility page before your visit.
Which Flagstaff family adventure is best for very young children?
The Arboretum at Flagstaff, the Museum of Northern Arizona’s Discovery Room, and the Rim Trail at Walnut Canyon are the friendliest options for toddlers and preschoolers. Each has short distances, shaded areas, and the option to sit, snack, or take a break without losing the experience.
How many days do we need to cover most of these family activities?
Three full days is comfortable for the eight adventures above without rushing. Pair Sunset Crater and Wupatki on one morning, group the museum and Lowell Observatory by neighborhood, and spread the outdoor sites across cooler mornings.
