Three Valley Gap is an unincorporated settlement and small resort and heritage-themed amusement park on the Trans-Canada Highway located on and adjacent to the lake of the same name, southwest of Revelstoke just west of the summit of Eagle Pass. The three valleys of the name include the eastern and western egresses from the pass and a southward opening into the upper reaches of Wap Creek, which is a northern tributary of the Shuswap River.
