The community of Pemberton is about 12 km upstream from the head of Lillooet Lake, while the eastern edge of the Mount Currie Indian Reserve of the Lil'wat branch of the St'at'imc people is the lakeshore itself. The eastern ramparts of the mountain ranges of Garibaldi Provincial Park overlook Lillooet Lake from the west, while to the east are the northern reaches of the Lillooet Ranges which lie between the Lillooet-Harrison drainage and the Fraser River.
