McCoy Flats BLM is a mt bike focus recreation area with a network of excellent nonmotorizrd singletrack trails. Dispersed free camping allowed, and currently there are several nice vault toilets scattered along the main access paved road.

This camping area is at the third new vault toilet. Lots of room for large TTs. No trash dumpsters and no water, but cell signal is excellent 5g five bars. Only few miles from main hwy on an old paved pothole filled road. And then only 3 miles back into Vernal and a Walmart on this end of town, so logistics are very good.
