The Amasa OHV trail is located approximately 51 miles west of Delta, Utah.  This trail system offers ATV riders 33 miles of desert and mountain terrain ranging from easy to more difficult. Old mines and mining relics in Miller Canyon are one of the highlights along the largest loop of the trail system. The trail also borders the Notch Peak Wilderness Study Area. Notch Peak is a 3,000-foot sheer cliff made of limestone and is considered by many as the second tallest cliff face in America, second only to El Capitan in Yosemite National Park. The peak towers 9,725 feet above the desert valley which has an elevation of approximately 5,000 feet. Riding is not allowed in the Notch Peak Wilderness Study Area. Another highlight of this trail is the Sink Hole. This 90-foot deep sink hole is thought to have been carved by an ancient river that ran beneath the surface until it finally collapsed. The Route 5 on the trail system takes you right to the fence that surrounds this large hole to protect it from wandering cattle as well as unsuspecting people. The trails are extremely well marked with most junctions listing the trail numbers, difficulty rating, and GPS coordinates. Elevations range from 5,400–9,000 feet. In the lower elevations you will be riding through pinion and juniper and in the higher elevations aspen, fir, and bristlecone. The best time to ride is late spring through late fall. This is truly God’s country, scenic trail riding at its best!

There is plenty of room to camp at the staging area. Vault toilet, grills, picnic tables, and shelter are located at the staging area. Bring your own drinking water as none is available along the trail or staging area. If you are self contained, you may want to continue up Miller Canyon about 3.6 miles or so past the trailhead; there you will find several old building sites that make nice camp areas among the trees. The standard 14-day BLM camping limit applies.

Getting There:

Starting from I-15 in Nephi, Utah head southwest on SR-132 to Lynndyl, then west on US 6 to Delta. From Delta continue west on US 50/6 approximately 40 miles to milepost 51.5 where you will see a sign directing you to Amasa Basin OHV Trails. Travel the well-graveled road to the northwest for 11 miles to the trailhead.
