Best Dispersed Camping near Mammoth, AZ

Several Bureau of Land Management (BLM) dispersed camping areas surround the Mammoth, Arizona region, with the closest options including Mount Bigelow Dispersed, Cactus Forest Dispersed, and Redington Pass Dispersed. These primitive sites permit camping without designated facilities and typically allow stays up to 14 days. The public lands near Mammoth feature multiple free camping zones on unimproved terrain, particularly in the desert landscapes between Tucson and Oracle, where saguaro forests and desert vegetation dominate the scenery.

Access roads to dispersed sites vary significantly in quality and difficulty. Many require high-clearance vehicles, with areas like Cactus Forest Dispersed offering easier entry points for the first few sites before deteriorating into rough terrain with narrow, sandy passages. Redington Pass presents challenging off-road conditions with numerous washouts and rocky sections. Most areas lack drinking water, restrooms, trash service, and hookups of any kind. Fire restrictions commonly apply, with temporary bans during dry seasons. Cell service ranges from good to non-existent depending on proximity to major roads and elevation.

The landscape provides distinct desert camping experiences with abundant wildlife viewing opportunities. Campers commonly encounter cactus forests dominated by saguaros, chollas, and palo verde trees. Visitors should exercise caution regarding desert wildlife. "We saw horseback riders and ATVs enjoying the area. We were able to stay in contact (ATT) and the city is within an easy drive for supplies," noted one camper at Snyder Hill BLM. Another visitor warned about natural hazards: "If you camp here you are IN THE desert...I came across 6 rattlesnakes, more camel spiders than I can count, brown recluse spiders, packs of coyotes rolling through at night and early morning." Target shooting is prevalent in several areas, particularly near Cactus Forest, where gunfire noise can continue throughout daylight hours.

    Snyder Hill BLM Camping Area

    Boondocking Area

    Bureau of Land Management site. 14 day limit. Easy access and we were able to park our 42 ft motor home easily. The area is quiet with trails and lots of area to walk your four legged camper! We saw horseback riders and ATVs enjoying the area. We were able to stay in contact (ATT ) and the city is within an easy drive for supplies. This is a boondock area. Be aware that while camping here you are sharing the area with wildlife (including rattlers). Boondocking etiquette applies (pick up trash and leave the area cleaner than when you arrived). We have camped here several times and will certainly return!

    Ironwood Forest BLM National Monument Pump Station Dispersed

    Good access and popular

    This seems to be the popular dispersed camping area along North Pump Station Road within the BLM Ironwood Forest National Monument. Numerous dispersed sites along a two track dirt road on both sides of the main gravel road. Free dispersed, 14D limit. No water, trash, toilets or designated spots. Cell signal is very good and OTA tv is also very good. Last mile or so from end of pavement is a wide graded dirt road accessing the dispersed sites from either direction, however the Silverbell road access seems to have a narrow bridge with a 6k weight limit?, So access to this site is from the south on gravel west El Tiro Rd for larger rigs?

    (Note that State land is adjacent and also offers dispersed camping sites but an AZ state lands permit would be required on State lands.)

    One negative issue is the constant target shooting from adjacent State lands.

    Cactus Forest Dispersed

    Feels secluded, but close to I-10 and Tucson

    We were surprised on the number of people who ventured out to this BLM spot off Park Link Road in the Cactus Forest over a rainy weekend in Tucson.

    The first dozen dispersed spots were full with camper vans, small trailers and trucks. We continued to drive down the gravel dirt road to a more secluded spot. We didn’t see anyone in our one-night stay beside a mountain biker in the morning.

    Even though It was raining in the area for about 24 hours before we travelled to the campsite, we didn’t have any issues navigating the 1.5 miles down to the site we chose. The truck has some mud in it and the 4x4 wasn’t needed (but made it easier). I would recommend a high clearance vehicle to reach the further back spots. Also, the road was narrow, our F250 brushed a few bushes on the way.

    Most dispersed sites had a fire ring (check locally fire conditions first). I’d suggest bringing in fire wood unless you just want to burn the few fallen twig and limbs. It’s a cactus forest- so the terrain is mostly saguaros, chollas, Palo verde trees and shrubs.

    Our site had a beautiful view of the sunset and a view of Picacho Peak in the distance. We visited in February and the weather was nice (on the chilly side) for our roof top tent. I wouldn’t come here in the summer unless we had a rig with air conditioning. Impressive view of the stars at night. Some traffic noise from I-10.

    No water, toilets, or trash. So be prepared to take out what you bring in. We had 2 bars of LTE slcell service with T-Mobile.

    It’s BLM land close to Tucson, so locals use the area for gun target practice. We heard gun shots until the sunset and starting again the morning. It was basically non-stop. If you want a place to shoot, this would be a good spot to camp.

    🌵 Saguaro Facts: Saguaros can live to be 150-200 years old and grow as tall at 40 feet. A 10 year old saguaro Is about 1.5 inches tall (please watch where you drive, park and step). At 80 years old, it’s around 6 feet tall and starts to bloom. The best time to see saguaro blooms is mid-May through mid-June. At age 95-100, it’s around 15 feet tall and starts to grow it’s first arm. 🌵

    Snyder Hill BLM Camping Area

    Quiet & Very Close to Saguaro NP (west)

    This BLM property, right off the Ajo highway near Tucson, is extremely convenient for a short or extended stay. Anyone can stay up to 14 nights, free of charge.  Greeted people here from all walks of life -- from those living out of the back of truck to brand new 45 foot motorhomes.

    Like many high-impact BLM areas, the entrance roads are not well-maintained so some are quite rough. We arrived in the dark, which we do not recommend as it was difficult to see where the entrances were and how rough the roads were ahead of us. The parking/camping spaces are not designated, but heavy use has carved out lots of opportunities. 

    There are a few places to walk or ride throughout the property, which is actually quite small based on typical BLM property.  However, the nearby areas of Saguaro National Park and Tucson Mountain Park, offer plenty of opportunities for both. 

    No facilities, no water or even a stream…so plan ahead!

    BLM Ironwood Forest National Monument - Reservation Road Dispersed Camping

    Flat and Sandy but close in

    This free BLM dispersed area is at the southeast corner of the National Monument at jct of Mile Wide road and Reservation road. Access on either road is on a wide gravel road for about a mile Note that Mile Wide road has two narrow bridges with a 10k weight limit. Free dispersed, no water, toilets, fire rings, tables or trash containers. However cell signal is very good. This site is only a few miles from both Saguaro National Park and Tucson Mt Park. Entrance has an unlocked gate (close gate behind you) and a new fancy BLM sign. There was a sign in past visits noting no target shooting in the Ironwood monument but someone ripped it down. State trust lands are adjacent and intermixed in this area also. (Camping is allowed on State trust lands but you have to get an online permits for $20). Only 2 stars due to lack of saguaros or ironwood trees and other interesting vegetation, just a sandy flat plain with creosote bushes, but safe for dogs though! ATV use may be an issue on weekends. Seems target shooters are close by with no County Sheriff intervention and the dense dried grass makes campfires a risk. Also there is a high pitch machine noise from the water pump stations nearby that can be irritating. Two stars, maybe one star...

    AZ State Land North Pump Station Road Dispersed

    AZ State land dispersed

    AZ State trust lands adjacent to BLM Ironwood Forest National Monument. I noticed the state lands seem to have more trash than the adjacent BLM, hence the two stars. Note that AZ State Trust Lands require a permit to camp on, this permit is online and costs around $20 good for a year. Dispersed camping. No water, toilets or trash dumpsters. Cell signal is very good however.

    Snyder Hill BLM Camping Area

    Rough access free blm

    The Snyder Hill BLM area is a bit of a trashy rough road access site. No water, no toilets, 14d limit. Good cell and close to Tucson Estates. Tons of broken glass litters the ground, some campers are sketch on tents. Hwy noise could be a factor. BLM rangers visit weekly and that is good. Only use this area if you cannot get into Gilbert Ray CG instead. There is no CG in Saguaro NP West. Another free BLM is Ironwood Forest NationZl Monument but the BLM proposed to start charging a daily $15 camping fee there in 2025?

    Snyder Hill BLM Camping Area

    Nice stop of the highway.

    The BLM land had several entrances. We went in towards the end of the road, but found the parking was more level at the third or forth turn off. We came in after dark so it was hard to say the best direct route. The second turn in is very steep. We saw the dip when we went to leave and opted for the first turnoff closer to the light. The rocky hill was a nice walk with the dogs in the morning. Lots of rabbits got them excited. Not overly clean, but I would stop here again. The amenities are easy to access. This is one of the few areas I’ve seen where you can access BLM parking and get gas and groceries at the same exit. It’s about 8 miles off the highway. The area isn’t vast but large enough for privacy. It’s perfect for a quick overnight stop.

Guide to Mammoth

Dispersed camping sites near Mammoth, Arizona offer primitive desert camping experiences at elevations between 2,500-4,000 feet. Summer temperatures often exceed 100°F while winter nights can drop below freezing at higher elevations. Several Bureau of Land Management areas permit free camping with seasonal fire restrictions that vary based on drought conditions and wildfire risk.

What to do

Explore mountain terrain: Mount Bigelow Dispersed offers hiking opportunities with cooler temperatures in summer months. "Bunch of hiking trails near by, and perfect temperatures in the summer heat," notes one visitor to Mount Bigelow Dispersed.

Wildlife observation: Early morning and evening provide optimal viewing times for desert wildlife. At Cactus Forest, campers regularly spot native species. "We enjoyed waking up to the literal forest of cactus," reports a camper at Cactus Forest Dispersed.

Stargazing: Limited light pollution creates exceptional night sky viewing. "Unreal sunsets too," mentions one visitor to Cactus Forest Dispersed Site, while another camper at Ironwood Forest notes, "Very dark sky with lots of stars."

What campers like

Elevation escapes: Higher elevation sites provide relief from summer desert heat. "It was packed on the weekends, but holy cow, was it gorgeous... perfect temperatures in the summer heat," reports a visitor at Charouleau Gap Trailhead Camp.

Desert botany: The native plant communities create natural site boundaries. "The cactuses and shrubs provided enough privacy between each site for it to feel like it was just us out there, and shielded us from the road as well," notes a camper at Cactus Forest.

Scenic diversity: The region offers both desert and mountain landscapes within short distances. "Great spots along this road for dispersed camping. Saw some wild life like deer and turkey," shares a visitor at Mount Bigelow Dispersed.

What you should know

Seasonal considerations: Winter camping requires preparation for cold temperatures. "We got to the parking area about 7:40 PM on November 10th. Started up the road to the campsite about 2 miles further up the mountain but at about 1/2 mile the road was so icy that we lost traction. Snow on the ground by the road," reports a camper at Mount Bigelow Dispersed.

Road conditions: Many sites require cautious driving. "The washboard road getting to the coordinates is worse than the road within the dispersed camping area! There are a few good rolling bumps and small ditches but going slow will help," advises a visitor to Ironwood Forest BLM National Monument.

Capacity fluctuations: Weekend occupancy significantly exceeds weekday use. "Very crowded on the weekend but the crowd is friendly and respectful. Great way to escape the summer heat of Tucson! Bring your hats and gloves," notes a camper at Mount Bigelow Dispersed.

Tips for camping with families

Cactus safety: Desert vegetation presents hazards for children and pets. "My only advice here is that it's not fun for dogs. (And maybe not fun for kids either?) It's incredibly prickly everywhere. Imagine that, prickly in the cactus forest? You'll want to avoid wearing sandals too," cautions a visitor to Cactus Forest.

Supply planning: No services exist at dispersed sites. "No amenities, good cell service," notes one camper at Ironwood Forest, making advance supply purchases essential.

Terrain assessment: Scout camping locations before setup.
