The Lillooet Country's boundaries are loosely defined but recognizable to residents of the area. On the northeast, the edge of the Lillooet Country is marked by the summit of the Pavilion Mountain Road and the nearby eastern outlet of Marble Canyon. Down the Fraser Canyon, a spot known as the Big Slide on Highway 12, or the southern outlet of Fountain Valley, form the southwest boundary. On the northwest generally everything north to Churn Creek and Big Bar Ferry is considered to be Lillooet Country. On the west, generally the summit of Cayoosh Pass on Highway 99 near Duffey Lake is recognizable as a border of the modern meaning of the Lillooet Country. Similarly, Pemberton Pass at Birken Lake is considered to be the outer boundary of the modern Lillooet Country, though as noted the Lillooet River valley to its west was the historic core and namesake of the district. Similarly, the entrance to the Bridge River Country via Railroad Pass (aka Railway Pass) between the upper Hurley River and the upper valley of the Lillooet River is a recognizable regional demarcator for locals. A vague distinction is made between the Bridge River Country and metropolitan Lillooet such that the lower few miles of the Bridge River, being effectively part of Greater Lillooet, are considered Lillooet, whereas above that is in the Bridge River.
