Mount Trumbull Loop Dispersed

6 ReviewsAdd Review

Mount Trumbull Loop Dispersed provides free camping on Arizona State Trust Land with well-maintained gravel roads suitable for large RVs. The area accommodates Class A motorhomes up to 36 feet, with multiple level sites large enough for group camping configurations.

Reviewers consistently note the abundance of available spots and spacious layout. However, several mention significant litter issues including broken glass, discarded furniture, and shooting debris scattered throughout many individual camping areas. The main communal area near the entrance typically offers cleaner conditions. Road traffic occurs more frequently than expected for a dispersed area, and distant gunfire from recreational shooting is common.

Access requires crossing wet weather conditions carefully, though the main gravel road remains passable. Cell service reaches the area, and campers can explore nearby attractions including petroglyphs located a few miles away. Ben notes he "stopped here before starting the trek on Whitmore Canyon Trail to the Grand Canyon overlook."

A permit from Arizona State Land Department is required for overnight stays, despite limited signage indicating this requirement. Rangers actively patrol the area and enforce permit regulations. Campers should obtain proper authorization before arrival and prepare for cleanup around their chosen site.

STATE TRUST LAND, *NOT* BLM - PERMIT IS REQUIRED TO STAY HERE

My husband and I have been staying here for 10 days and we were planning on staying another 2 days, before moving on to cooler temperatures. Well, this afternoon, we got the dreaded knock from a police officer and a Ranger, who told us that this is state trust land, not BLM land, and a permit is required to stay here. We haven't seen any signs saying anything about that, but after reading the reviews here, it looks like one person mentioned it. 

It's a busy, very dirty location, with tons of trash (literally there are dirty mattresses, old couches, bags of trash strewn everywhere - it's awful. I've never been to Slab City, but it's one step up from how I imagine it is) and big shards of broken glass in most of the camping spots, so I wouldn't recommend parking in any of the single spots. We chose to stay in the big communal area close to the entrance, even though we hate being close to people, because it was the only place that didn't have broken glass, and we've just been waiting out the cooler temps at our higher elevation spots. 

On the plus side, the road is well kept gravel and almost all of the spots are huge and level. We have a 36' Class A and we fit into all of the spots, with room enough for a shorter Class A, a Class C or several toads to fit alongside us. It's really too bad that people are so irresponsible and selfish, because if there were no trash or glass, I'd give this place 5 stars, for how giant the spaces are, how many spaces are available, how flat the spaces are and how well maintained the road is. Also, people keep to themselves and it's relatively quiet most days and nights, so it feels pretty safe. But again, BE SURE TO GET A PERMIT BEFORE COMING HERE, or you'll definitely get THE KNOCK.

If we hadn't gotten THE KNOCK, I would have given it 2 1/2 stars, with points taken off for the spots being full of broken glass and trash, but I only gave it 1 star because I'm feeling salty about the fact that it requires a permit. Lol.

Something always available here

We were happy to be here after a long drive and failed searches .  I would use this area as a failsafe-always something available here.  There is a lot of shooter trash along the whole road but we were able to go to a spot with the trailer off the road aways where there wasn't much junk .  Nice enough base to explore the region where we could let the dog roam around.  The road is busier than you would think so if you have a spot close to the road I wouldn't let dog loose.

Average Desert Campground

Not much to tell it’s a standard desert campground. Heard quite a bit of gunfire and there are some obvious signs people had targets set up along the access road. Lots of litter which is unfortunate to see. I have neither the time nor the crayons to explain how easy it is to not litter.

Great free camping

Lots of space for camping. Fairly decent roads. Just don't come out while it's wet. Fair bit of trash around hillsides where people are shooting.

Great place to stop before the grand canyon

Stopped here before starting the trek on Whitmore Canyon Trail to the Grand Canyon overlook. Great place to stay with LOADS of spots. Plenty of room for everyone and plenty of big spots for groups. Lots of cool hills and jumps for wheeling. Also just a couple miles from the petroglyphs.
