Trail Overview

Eggnog Star Springs Road-BLM13000 is a 26.7-mile point-to-point trail rated 3 of 10 located in Garfield County, Utah on the southernmost section of the Henry Mountains. Eggnog Star is a two-track road that is generally suited for 2 or 4WD vehicles. However, it should be noted that several creek crossings may be wet or washed out depending on conditions. Eggnog Star Springs is the major east/west trail through the southern portion of the Henry Mountain Recreational Area. The western end of this trail creates the southern boundary of the Mt. Pinnell Wilderness Study Area (WSA). Four distinct biological life zones are within the WSA due to nearly 5,000 feet of elevation change. Portions of the WSA are summer range for the Henry Mountain bison herd, and bison are frequently seen in the vicinity of The Horn. Cougar, a wildlife species associated with wilderness, inhabits the WSA. Peregrine falcons bald eagles, and five animal species that are considered sensitive may inhabit the WSA. Further east the trail wraps around the southern end of Dial Knob rising to 5000 feet on the north side of the trail. The trail continues to climb past Johns Knoll with the trail cresting at 6200 feet before descending and ending at Highway 276. The Henry Mountains and the surrounding deserts are located in south-central Utah, just north of Lake Powell. Here, almost 2 million acres of public land are administered by the Bureau of Land Management. The Henry Mountains are also notable for the free-roaming herd of bison that live there, one of only four such herds in the country (the other 3 are in Yellowstone Park). The population was established in 1941 after the relocation of 18 individual bison from Yellowstone National Park. Today the herd is estimated to be between 250 and 400 bison. There are more than a thousand miles of off-highway trails available throughout the Henry Mountains. Cell phone service is intermittent to non-existent and the nearest services are in Hanksville to the north. There are several gas stations along Highway 276 between the Bullfrog Marina and Hanksville.

The trail/road was relatively easy with just a few interesting/challenging sections. Nothing that a 4 WD vehicle couldn't handle. Even a 2-wheel vehicle with a little clearance could do. This is a trail for the views of the surrounding area. The view of the Henry Mountains is outstanding. The colors of the soil and geological formations are striking...Brown, tan, light gray, dark gray, black and with some Bentonite Hills thrown in and with a background of deep blue sky it is visually stunning. We think the name "Eggnog" comes from the colors of a lot of the soil in the area. If anyone knows different please let us know. One thing that was unexpected, there was a natural spring called "Saleratus Spring" about 7 to 8 miles in that was literally an oasis in the desert. We started this trail from the Notom-Bullfrog Road. This 23 mile trail ends at the Starr Springs Camp Site. There are some relatively "Modern Ruins" there of an abandoned commercial site. Full disclosure, we did this trip in the Fall of 2025.
