Mount Nebo, for years, was falsely dubbed the second tallest peak in the Wasatch, behind Mount Timpanogos. Once Mount Timpanogos was properly recorded from a summit elevation of 12,008 feet to 11,749 feet, Mount Nebo reclaimed its title as the Wasatch's tallest peak at 11,928 feet. Named after the biblical Mount Nebo in the Old Testament, the massif is composed of three large peaks with the north peak as the true summit.

Mount Nebo forms the last massif on the south end of the Wasatch Range. Its west face towers over the town of Mona, climbing nearly 7,000 feet above the valley floor in roughly 3 miles. Mount Nebo is a stunningly beautiful and rugged mountain. Reaching its summit is strenuous and difficult regardless of the route you choose.

The easiest routes start on the east face of Mount Nebo. The easiest is the North Ridge route. The trail travels around the west face of North Peak and gradually rises 3,000 feet over 4 miles. The Nebo Bench route is one notch up the difficulty scale. The route travels the east face of North Peak. It gains most of the 3,000 vertical feet in the last 1.5 miles. The most difficult route on the east face of Mount Nebo is Andrew's Ridge route. This route is a grueling 16-mile round trip from the south aspect.

During the winter months, the safest, yet most technical, routes to summit Mount Nebo lie on the west face. The Jones Hollow route is a spring route that gains 6,000 vertical feet up the north end of the west face. The Northeast Couloir route is also a spring route that travels the north end of the west face. Cedar Ridge is a winter route that gains the same elevation on the south end of the west face. All of these winter and spring routes are serious climbs that require solid mountain experience. Narrow ridges, 60-degree slopes, massive cornices, and serious exposure keep most people off this mountain in the winter and spring.
