Red Castle is set within the High Uintas Wilderness on land managed by Uinta-Wasatch-Cache National Forest.

[1] It is one of the most distinct and photogenic landforms in the Uinta Mountains,[4] and it is considered the crown jewel of the range.

[5] Topographic relief is significant as the summit rises 1,500 feet (457 meters) above East Red Castle Lake in one-half mile (0.8 km).

The mountain's descriptive toponym has been officially adopted by the U.S. Board on Geographic Names.

[3] Based on the Köppen climate classification, Red Castle is located in a subarctic climate zone with cold snowy winters and mild summers.
