Twelve Mile Flat

SUMMARY PRESENTED BYT-Mobile

Manti-La Sal National Forest's Twelve Mile Flat sits at over 10,000 feet elevation, reached via 18 miles of unpaved road with a steep grade that demands working brakes and a low gear on the descent. The elevation means cold nights even in summer, with temperatures dropping into the upper 30s and low 40s regardless of valley heat. Sites are generally sloped and may require leveling blocks, particularly outside the group areas. The campground includes drinking water, toilets, and picnic tables, and accepts RVs up to 35 feet. The season runs late June through October. Ferron Reservoir Campground sits roughly 2 miles northeast for campers who want a nearby alternative with lake access.

Total isolation......sort of.

This is the place if you like being "off the grid". 18 miles of unpaved (and, for us, muddy) road to get to the campground. It's a 90-minute trek each way from the closest gas/food/retail, so be prepared. It's also a fairly aggressive grade up and down. Brakes and transmissions will need a chance to recover the climb/descent.

Altitude is also a major factor. This is over 10,000 of elevation. Our lungs definitely felt it. While Salt Lake City was hitting 100 degrees, we were sleeping with three blankets at night as temps were in the low 40s/upper 30s.

This campground is definitely not level. Outside of the group sites, most of the spots are sloped, and ours might have been the worst. We needed leveling blocks to lift our pop-up about 8 inches on the dedicated "pad" and there was no flat spot to set up any canopy or EZ Up. Our site did have plenty of shade with direct sun from about 8 am to noon.

We did have a couple of issues that will deter us from coming back. First was the constant flow of ATVs/OHVs/vehicles coming into the campground to use the toilets and unused sites for lunch/dinner. Since there was no camp host on site, this felt a little abusive. There are several open sites along the road to the campground and more as you continue up Skyline Drive. I think everyone using them knows that this is basically a truck stop for them.

The second issue we had was the moths. Having a pop-up, we understand that critters happen. But we must have had over 100 moths that found shelter under our flaps, in the roofline, and inside our camper. It added 45 minutes to our breakdown and pack up.

Those issues, coupled with the long and rough road, make this place a one-and-done campground for us.
