Lyman is on U-24, 3.2 miles east of Loa, 5.3 miles north of Bicknell and ca. 18 miles from Capitol Reef National Park. The Fremont River flows through the valley to the west. Imposing 11,306' (3,446.07m) Thousand Lake Mountain is located ca. six miles to the east. The settlement has had several names, East Loa, Wilmoth and finally Lyman to honor Apostle Francis M. Lyman, of the LDS Church.

According to local residents, while being pursued by a posse, Butch Cassidy and the Sundance Kid hid out in a now abandoned Lyman house owned by the Chappel family.
