Abajo Mountains

The Abajo Mountains lie in southeastern Utah, USA, within the Manti-La Sal National Forest. Known by locals as the Blue Mountains, the range is a local secret, offering scenic drives and little foot traffic on your hikes. Some trails also accommodate mountain bikes, dirt bikes, and horses. The range has 17 mountains. The highest and most prominent is Abajo Peak at 11,358 ft (3,462 m) tall and with a prominence of 4,551 ft (1,387 m).

Located in San Juan County in southeastern Utah, the Abajo Mountains are not well known by outsiders and offer solitude on the trail. The range falls within Manti-La Sal National Forest and part of Bears Ears National Monument, south of Canyonlands National Park, and near the Dark Canyon Wilderness Area.

The Abajo Mountains stretch approximately 16 mi (26 km) long and 10 mi (16 km) wide. They can be divided into two parts. The northern section, Shay Mountain, is much smaller and almost entirely separate from the southern section. When referring to the southern section, it is often further divided into eastern and western sides. Abajo Peak is the tallest point in the range at 11,358 ft (3,462 m).

Drainage ways radiate out from the mountains. North Cottonwood Creek flows to the northwest. Titus Canyon, Shay Canyon, Harts Draw, and Indian Creek drain to the north where they all empty into the Colorado River. Spring, Vega, North, Pole, South, Verdure Creeks flow east into Montezuma Creek and from there into the San Juan River. Recapture and Johnson Creeks, Dry Wash, Allen Canyon, and Mule Canyon flow to the south and southwest.

The range is also known as the Blue Mountains. The Colorado border is only 25 miles (40 km) away and Monticello and Blanding are the closest small towns. The name Abajo means below in Spanish. One idea is that the name originated from the range’s location below the fords of the Colorado and Green Rivers. Another possible explanation is because the mountains’ rounded peaks seem lower than the jagged peaks of the nearby La Sal and Henry Mountains.

The mountains are popular with locals for hiking, fishing, mountain biking, climbing, horseback riding, hunting, scenic drives, and riding motorcycles. In winter, the trails and slopes are ideal for cross country skiing, backcountry skiing, snowshoeing, and snowmobiling. There are several lakes for anglers to utilize including Loyd’s, Foy, and Monticello Lakes.


The range formed 35 million years ago as the Colorado Plateau began to lift. The Abajos are distinct in that they are one of only two volcanic ranges in southeastern Utah. These laccoliths formed as magma slipped through cracks in the sandstone layers, rather than via explosive volcanic action. The range is primarily composed of granitic type rock but without the cliffs and spires often seen with granite structures.

Three ecological zones are present in the range. Along the mountains’ base is upper Sonoran desert landscape, characterized by sagebrush, alkali plains, and piñon pine and juniper. Scrub oak, manzanita, and low shrubs grow along the upper edges of this zone.

The transition zone begins along the slopes. Here there are grassy valleys, bushes such as elderberry and serviceberry, aspen, maples, willows, alders, and cottonwoods. Moving up to the boreal zone at the range’s higher elevations, the forests consist of Engelmann spruce, balsam fir, limber pine, and foxtail pine.

The region experiences long summers and short winters. The mountains receive up to three times more precipitation than the surrounding canyons and mesas.

Several endemic and rare species exist in the range, among them Chatterly’s onion, the Abajo Daisy (endemic to the range), Abert’s squirrel, three-toed woodpeckers, and the many-lined skink. Common species, though not always seen, are black bear, mountain lion, mule deer, and elk.

Human History

The Abajo Mountains were part of the ancestral hunting territory of several Native American tribes. Although there is not much evidence found at higher elevations, numerous sites and rock art along the lower slopes and foothills indicate that Native Puebloans used the area extensively during the 800s.

Later the Weeminuche Utes and San Juan Band Paiutes moved into the region. They were able to establish camps with sufficient water and natural resources for foraging and hunting. The range was also used by Navajos to collect herbs and parts of trees for medicinal purposes.

During the early and mid-1800s, the Old Spanish Trail ran near the base of the mountains. Despite this traffic, it was not until the 1880s that cattle companies moved in and began to graze cattle in the mountains during the summer. This influx of ranchers created competition for resources with Native Americans.

The towns of Monticello and Blanding were founded in 1887 and 1905 respectively. This naturally increased the permanence of settlers in the region who quickly branched out to support themselves through managing livestock, farming, lumbering, and mining.

In 1907, Theodore Roosevelt created the Monticello Forest Reserve in the Abajo Mountains and Elk Ridge. Two years later, the area was officially changed to La Sal National Forest.

Best Hikes in Abajo Mountains

Except for the road to the summit of Abajo Peak, there are no trails to peaks in the range. Hikers can forge their own path cross country but should be confident navigating and prepared with gear for all weather conditions. The Forest Service has a pamphlet with information on trails for hiking, biking, motorcycles, and driving routes, including what trails are open at what time of year.

Abajo Peak

One of the more popular scenic drives is Abajo Loop. The road travels across the mountain range and ends on the north side near Highway 211 and Canyonlands National Park. From the loop, one can take a spur road called South Creek Road to summit Abajo Peak. Hikers can also follow the road, or attempt to find their own path to the top.

There are several communication towers on the summit and the Abajo Loop is not recommended for larger RVs and trailers.
