You’ll find Sunset Crater Volcano National Monument and the adjacent Bonito Campground one of northern Arizona’s most striking places to camp, where pine-covered cinder cones meet dramatic basalt lava fields under world-class dark skies. Located just 15 miles northeast of Flagstaff at an elevation of nearly 7,000 feet, this volcanic landscape provides an ideal basecamp for hiking rugged trails, exploring ancient geological events, and stargazing in an internationally certified dark sky corridor.
Quick Answer
Camping is not permitted inside Sunset Crater Volcano National Monument itself. Instead, visitors camp directly across from the visitor center at Bonito Campground (44 sites, seasonal May–October, managed by the U.S. Forest Service) or use free dispersed camping on adjacent Coconino National Forest land. Reservations for Bonito Campground can be made up to 6 months in advance on Recreation.gov.

Why Sunset Crater Is a Must-Visit for Campers
Formed by a dramatic eruption around 1085 CE, Sunset Crater Volcano is one of the youngest volcanic features on the Colorado Plateau. Camping here places you at the crossroads of raw geological history and high-desert ponderosa pine forests. Because the volcanic cinder gravel absorbs heat during the day and the park sits at 6,900 feet elevation, you will experience warm daytime exploration followed by crisp, cool nights perfect for campfires and stargazing.
The monument connects directly to the 34-mile scenic loop leading to Wupatki National Monument, allowing campers to easily combine volcanic geology with ancient Puebloan architectural sites in a single weekend. Whether you are pitching a tent beneath towering ponderosa pines or setting up an overland rig for a dark-sky photography session, the landscape offers an immersive outdoor escape just 25 minutes from downtown Flagstaff.
“Sunset Crater offers a stark reminder of the planet’s dynamic power—where black basalt lava flows meet resilient high-country pine forests under pristine night skies.”
The Bonito Campground: What to Expect
Located directly across the road from the Sunset Crater Visitor Center, Bonito Campground is the primary developed camping facility in the area. Managed by the U.S. Forest Service (Coconino National Forest), the campground operates seasonally from late May through mid-October.
Note: Bonito Campground is a dry campground. There are no individual water, electric, or sewer hookups, and no RV dump station is available on-site. Potable drinking water spigots and modern flush restrooms are spaced throughout the loops.
- Site Inventory: 44 single-family campsites suitable for tents, camper vans, and RVs up to approximately 42 feet.
- Amenities: Paved parking spurs, picnic tables, fire rings with cooking grates, flush toilets, and seasonal potable water.
- Reservations: Available through Recreation.gov on a rolling 6-month window. First-come, first-served sites fill rapidly on summer holiday weekends.
- Wildlife: Expect frequent visits from Abert’s squirrels, Steller’s jays, common ravens, and mule deer. Keep all food locked in hard-sided vehicles to protect local wildlife.
Pro Tip: Sites on the outer western loop back up directly against the Bonito Lava Flow, providing dramatic volcanic views right from your picnic table.
Trails and Lava Features to Explore
The monument features a well-maintained network of hiking trails that wind through rugged basalt formations, cinder dunes, and resilient flora. Because volcanic rock is abrasive and sharp, sturdy closed-toe hiking shoes and plenty of water are required on all routes.
- Lava Flow Trail (1.0 Mile Loop): The monument’s flagship trail. The first 0.25-mile loop is paved and fully ADA-accessible, guiding you past squeeze-ups, hornitos, and the base of the main cinder cone. The rougher gravel loop extension takes you deeper into the Bonito Lava Flow.
- Lenox Crater Trail (1.6 Miles Round-Trip): A moderate climb gaining approximately 200 feet in elevation up a neighboring, older cinder cone. The summit delivers panoramic views of the San Francisco Peaks and Sunset Crater.
- Lava’s Edge Trail (3.4 Miles Round-Trip): Stretches from the Visitor Center to the Lava Flow Trailhead, weaving along the boundary between the ponderosa pine forest and jagged a’a lava.
- Aa Flow Trail (0.3 Miles Round-Trip): A short trail located along the park road featuring interpretive signs detailing the differences between smooth pahoehoe and rough, clinkery a’a lava.
Warning: Climbing to the rim of Sunset Crater Volcano itself is strictly prohibited. The trail to the summit was permanently closed in 1973 due to severe erosion and scarring of the delicate cinder slopes. Hefty federal fines apply for off-trail violations.
Backcountry and Dispersed Camping Regulations
To preserve the delicate volcanic ecosystem, no overnight backcountry camping is permitted within the boundaries of Sunset Crater Volcano National Monument. However, free dispersed camping is widely available on the surrounding public lands of the Coconino National Forest outside the monument boundary lines.
- Designated Motor Vehicle Use: Dispersed camping is permitted along designated Forest Service roads (such as FR 545A and areas near Cinder Hills OHV). Always consult the official Coconino National Forest Motor Vehicle Use Map (MVUM) before driving off paved highways.
- Leave No Trace: Pack out all trash, human waste, and food scraps. The high-altitude volcanic cinder soil does not break down organic waste quickly.
- Fire Restrictions: Northern Arizona frequently enters Stage 1 or Stage 2 fire restrictions during late spring and early summer. When bans are active, all charcoal and wood campfires are prohibited; only portable gas stoves with an on/off shutoff valve may be used.
- Stay Limits: Dispersed camping on Forest Service land is limited to a maximum of 14 consecutive days within any 30-day period.
Nighttime Activities: Stargazing and Photography
Sunset Crater Volcano National Monument is certified as an International Dark Sky Park. Shielded by the San Francisco Peaks and strictly enforced lighting codes across the greater Flagstaff region, the monument boasts exceptionally dark Bortle Class 2 skies that offer sweeping views of the Milky Way, star clusters, and seasonal meteor showers.
- Optimal Timing: Plan your trip within 4–5 days of the new moon for the darkest skies. The Milky Way core is most prominent from late spring through early autumn.
- Astrophotography Setup: A wide-angle lens ($f/2.8$ or faster), a sturdy tripod to withstand high-desert winds, and 15-to-25-second exposures produce crisp images using the dark silhouettes of ponderosa pines and jagged lava for the foreground.
- Dark Sky Etiquette: Use red headlamps only to preserve your night vision and prevent light pollution for other stargazers. Standard white flashlights and high-beam vehicle lights are discouraged in designated viewing pullouts.
Frequently Asked Questions
Can you camp inside Sunset Crater Volcano National Monument?
