Cinder Hills and Its 13,500 Acres
Cinder Hills can look deceptively simple on a map: a wide field of dark volcanic cinders near Flagstaff, with room to ride and routes that can be hard to read from the seat. This guide explains what the area is like, how to plan a visit, and how to ride thoughtfully around changing terrain, weather, and access rules.
What to Expect at Cinder Hills
A volcanic landscape, not a groomed trail park
Cinder Hills is a large off-highway vehicle riding area north of Flagstaff, near Sunset Crater Volcano National Monument. The dark, loose volcanic cinders give the landscape its distinctive look, but they also shape the ride. A route that seems straightforward from a distance can feel soft, bumpy, or tiring once you are moving through it.
The area is commonly described as covering about 13,500 acres. That scale gives riders room to explore, but it does not mean every patch of ground is open for riding. Routes, boundaries, and closures matter. Stay on routes designated for motorized use, and use current land-management information to understand where riding is allowed before you unload.
Cinder Hills is not a conventional trail system with one obvious loop, signs at every turn, and a staffed visitor center to sort out every question. Some riders arrive expecting a neatly marked circuit and find a broader landscape of routes, open riding areas, and volcanic terrain instead. If you prefer a defined route, plan one before you arrive rather than relying on the idea that you can simply follow tracks left by other vehicles.
Loose cinders change how a machine handles
The surface can shift beneath your tires, especially on slopes, in churned-up areas, and where traffic has pushed loose material into deeper pockets. On an ATV, the rider may need to make small steering corrections and keep momentum measured and steady. A side-by-side can feel more planted, but its extra weight does not make soft ground disappear. Sudden turns or abrupt braking may still unsettle the machine.
Loose terrain is tiring in a different way from rocky single-track. Riders may not be negotiating large obstacles every minute, yet the constant movement of the surface can make hands, shoulders, and concentration work harder. New riders sometimes grip the bars tightly and look directly at the front tires. Try to relax your grip and look farther ahead, so you have time to spot changes in the surface and adjust smoothly.
The cinders can also hide small ruts, rocks, or changes in grade. Leave enough space between vehicles to see the terrain and avoid riding directly in another machine’s dust. That gap gives you more time to respond if the rider ahead slows, stops, or kicks up a sudden cloud.
Plan around the type of ride you want
Think about your group’s experience, equipment, and time before choosing a route. A relaxed exploration ride might call for a slower pace and frequent stops to check the map. A more confident group may want to cover more ground, but should still avoid treating open terrain as a reason to ride without boundaries or a plan.
Cinder Hills is also a place where conditions can make the same route feel very different from one visit to another. Rain, wind, recent traffic, and seasonal restrictions can affect the surface or whether a route is accessible. For route planning and mileage expectations, start with [Cinder Hills Trail Mileage] and [Cinder Hills for Beginners], then check current access details before leaving home.
Plan Your Route and Access Before You Arrive
Check the designated routes and area boundaries
A useful route plan starts with a current motor vehicle use map or other official land-management map for the area. Look for route designations, boundaries, and any seasonal restrictions or closures. A trail visible in a phone app is not automatically an authorized motorized route, and a worn track on the ground is not proof that riding there is permitted.
Digital tools can make planning easier when you are comparing route lines, locating a staging area, or trying to see how a route connects with the surrounding forest. onX Offroad can be useful as a navigation aid, but do not treat an app as a replacement for official route information. Download what you need before heading into areas where cell service may be unreliable, and compare your route with the land manager’s current map.
If you are uncertain whether a route is open, choose a clearly designated option or pause to check rather than riding ahead and hoping the route is allowed. That moment of caution is less frustrating than discovering later that a shortcut crossed a closed area or sensitive ground. [Reading an Arizona Motor Vehicle Use Map] offers a helpful starting point for understanding how to read route designations.
Know the access point and the last-mile details
Many visitors use Forest Road 776 to reach the Cinder Hills area. Before driving out, confirm the access information and the road conditions that apply to your planned visit. Forest roads can be affected by weather, maintenance, closures, and the condition of the vehicle you are using to tow. A road that appears close to town on a map can still take longer than expected when you are hauling a trailer.
If this is your first visit, it can help to review [Getting to Cinder Hills on FR 776] and [Cinder Hills OHV Area Access]. Make sure the tow vehicle, trailer, and machine are all prepared for the trip. Check that the trailer is secured, the tires are in good condition, and the load is balanced. If your group is meeting at the staging area, share a clear meeting point and a backup plan in case someone arrives late or loses phone service.
Give yourself time to unload, check gear, and orient the group before riding. Rushing through the first ten minutes can lead to a missed strap, a forgotten water bottle, or a route choice no one has discussed. Staging areas can also be busy, so park and unload in a way that leaves room for other visitors to maneuver.
Build a route that has a comfortable turnaround point
Choose a route with a realistic turnaround point, not just an ambitious destination. Estimate how long the ride may take, then add time for stops, navigation, and unexpected delays. A short distance through soft ground can take longer than a longer route on a firm surface.
Agree on what the group will do if someone needs to turn back. If one rider is tired, a machine develops a problem, or weather moves in, the group should know whether everyone will return together or whether there is a safe, agreed-upon plan for splitting up. For most mixed-experience groups, staying together is simpler and safer.
Before setting out, make sure each rider understands the route and the basics of regrouping. You might choose an obvious junction, a staging area, or another easy-to-identify point as a place to stop if the group becomes separated. Do not rely on every rider being able to call or message from the trail. [Arizona Trailhead Parking and Staging] has additional planning considerations for arriving and getting ready at a trailhead.
Match the Ride to Your Machine and Experience
ATVs and UTVs each have practical trade-offs
The right machine depends on the riders, the route, and the way your group prefers to travel. An ATV is narrower and usually easier to position on a changing surface, but it requires the rider to manage balance and body movement. A UTV offers a seat and more protection around the occupants, but its wider footprint may limit where it can go. Check route width and vehicle restrictions before assuming a full-size rig can follow every track you see.
| Consideration | ATV | UTV |
|---|---|---|
| Rider involvement | Requires active balance and body movement | Seated driving with steering and passenger coordination |
| Width | Usually narrower | Can be wider, so route width matters |
| Group setup | Riders travel on individual machines | Passengers may ride together if the machine is designed for them |
| Loose cinders | Smooth, deliberate inputs help | Extra weight and width still require careful control |
| Planning priority | Rider skill and fatigue | Route width, passenger safety, and machine limits |
Whatever you ride, follow the machine’s capacity and passenger requirements. Do not add a passenger to a seat that is not designed for one, and do not assume that a roll cage or seat belt makes an unsuitable route safe. A machine’s capabilities do not replace good judgment or a careful route choice.
If your group has a mix of ATVs and UTVs, agree on a pace that works for the least experienced rider. The faster machine should not set the group’s speed simply because it can travel faster. Frequent, predictable stops are easier for everyone than a long gap followed by a rushed attempt to catch up.
New riders should make the first outing deliberately simple
A beginner can enjoy Cinder Hills without trying to cover a large portion of the area. Start with a short ride, keep the route easy to follow, and choose a pace that leaves room to learn how the machine responds to loose material. A rider who is comfortable on firm roads may still need time to adjust to a surface that shifts under the tires.
Practice basic control in a safe, appropriate area before committing to a longer route. Work on smooth acceleration, gradual braking, and looking ahead. Make one change at a time rather than trying to handle speed, turns, traffic, and navigation all at once. If the rider is tense, take a break and talk through what felt uncomfortable before continuing.
For a family group, consider the youngest or least experienced rider when planning distance and stops. Parents often focus on whether a child can keep up, but fatigue and attention can change quickly in a new environment. A shorter ride with a calm finish is usually a better introduction than a long outing that leaves everyone worn out.
Full-size rigs should verify route fit first
A broad riding area does not guarantee that every route suits every vehicle. Full-size side-by-sides should account for width, turning room, surface conditions, and any posted restrictions. A route that looks wide on a screen may narrow between vegetation or at a turn, and turning around can be difficult if the group has entered a tight or steep section.
Use an appropriate vehicle-width map or route information when available. [Arizona Trails Rated for Full-Size Rigs] can help frame the questions to ask before setting out. Check the machine’s dimensions against route requirements and do not assume that a route is suitable just because another UTV has used it.
Keep passengers informed about the plan and make sure everyone is seated and secured as the manufacturer requires. A passenger who is startled by a sudden turn or rough patch can distract the driver. Simple communication before the ride—where the group is going, when you will stop, and what to do if separated—can prevent confusion once the machines are moving.
Prepare for Weather, Water, and Changing Conditions
Take more water than a short ride seems to require
Flagstaff’s elevation means conditions can differ from Arizona’s lower desert, but riders should still plan for sun, exertion, and changing weather. A ride that feels comfortable at the staging area may become tiring when the group is moving, breathing dust, and stopping in exposed places. Carry water for every person and keep it accessible rather than buried under gear.
Do not wait until someone feels unwell to take a break. Check in regularly, especially with children, newer riders, and anyone who is not used to riding at elevation. Thirst, headache, unusual fatigue, dizziness, and nausea deserve attention. Stop in a safe place, rest, and reassess whether it makes sense to continue.
Pack water and basic supplies for the full outing, including the possibility that you will be delayed. [Water Planning for an Arizona Trail Day] is useful when deciding how to prepare for a remote ride. Also carry a charged phone, a basic first-aid kit, and any navigation or emergency equipment appropriate for your group.
Watch the sky and respect monsoon conditions
Summer weather around northern Arizona can shift quickly. A sunny start does not guarantee a dry ride, and storms can bring lightning, strong wind, and runoff. A wash or low point that seems harmless in dry weather may become unsafe after rain, including rain that fell somewhere upstream.
Check the forecast and land-management notices before leaving, then keep watching the sky during the ride. If thunder is nearby or storm conditions are building, do not press on simply to finish a planned loop. Turn around early when conditions suggest that continuing could put the group in a more exposed or difficult position.
Avoid entering flooded washes or crossing moving water. The depth and strength of water can be hard to judge, and loose ground may conceal erosion or debris. If you are uncertain, turn back and find a safer option rather than testing the crossing with a machine.
Treat fire restrictions and closures as part of the plan
Fire restrictions can affect what activities are allowed and where visitors can travel. They may change how you use equipment, whether certain areas are accessible, and whether a route is closed. Check the restrictions that apply to your intended area and date, and follow posted instructions even if other visitors appear to be ignoring them.
A closure is not a suggestion to find an unofficial detour. Riding around a barrier can damage land, create new tracks, and expose your group to enforcement or hazards. If a planned route is closed, use a legal alternative or choose another area for the day. Reviewing [Arizona Fire Restrictions by Stage] can help you understand the kinds of conditions that may apply.
Be mindful of fire danger even when your ride does not involve a campfire. Park only where permitted, avoid stopping in dry grass where a hot vehicle could pose a risk, and never leave trash behind. A careful visitor protects both the landscape and the ability of others to keep enjoying the area.
Ride Responsibly and Finish the Day Safely
Stay on legal routes and reduce your impact
The most important riding habit at Cinder Hills is staying within designated riding areas and on authorized routes. Riding beyond a route can damage plants, soil, and places that other visitors may be trying to protect. It can also create new tracks that confuse future riders about where motorized travel is allowed.
Do not assume that an open-looking patch of cinders is available for cross-country riding. Check the map and follow signs, barriers, and posted restrictions. If your route becomes unclear, stop in a safe place and confirm your location before moving on. A few minutes with a map is better than adding another unauthorized track to the landscape.
Keep noise and dust in mind, especially when other visitors are nearby. Slow down around people, give them room, and avoid unnecessary engine revving. Pack out litter, secure loose items, and leave the staging area as orderly as you found it.
Carry the documents and equipment your ride requires
Before riding, confirm that your machine has the registration, decal, or other documents required for its use and location. Requirements can differ depending on how the vehicle is registered, where it is ridden, and whether the rider is visiting from out of state. Review [What Arizona Riders Need Before They Ride] and [Arizona Rules for Visiting Riders] if you are unsure which requirements apply.
Bring the basics that are easy to overlook: a map or offline navigation, water, protective gear, a first-aid kit, and a way to contact help if service is available. Check the machine before unloading, including fuel, tires, controls, lights where applicable, and any safety equipment. A quick check can catch a problem while you are still near the vehicle and tools.
If a machine has a mechanical issue on the route, stop somewhere visible and safe if possible. Keep the group together, make the machine easy for approaching riders to notice, and avoid leaving a person alone in an unfamiliar area. Think through how you will get help or return to the staging area before the outing begins.
Leave enough time to return before fatigue takes over
Many riding problems happen late in the day, when people are tired, water is running low, or the group is eager to get back to town. Set a turnaround time that leaves a margin for delays. Do not use the last of your daylight or energy simply because the return route looks familiar.
At the end of the ride, take a moment to check that everyone is accounted for and that no gear has been left behind. Inspect the machine and trailer before driving away. If the ride was harder than expected, make a note of what you would change next time: a shorter route, earlier start, different tires, more water, or a clearer map plan.
Cinder Hills rewards preparation more than improvisation. Check access and route information, choose a ride suited to the group, and be willing to adjust when conditions change. That approach makes it easier to enjoy the volcanic landscape without turning a day out into a stressful scramble.
