T'sek Hot Springs, near the First Nation community of Skookumchuck (the name on older maps) and more recently as Skatin ("ska-TEEN")is on the historic Harrison Lillooet Gold Rush trail in the Lillooet River valley, south of Lillooet Lake, in British Columbia, Canada. The hot springs themselves, named Tsek in the St'at'imcets language (pronounced "chick" were on private property purchased from Goodwin Purcell family by the Tretheway family after his death in the 1909 and acquired by the Government of Canada in 2008 to be held in trust for the local aboriginal people until a potential treaty settlement.
Skookumchuck Hot Springs was also known as "'St. Agnes Well'" during the days of the Fraser Canyon Gold Rush also called the Douglas Road, along which it is located, while Harrison Hot Springs farther south was known as St. Alice's Well; both were named by Justice Bailey for the daughters of Governor Douglas.
Near the community of Skookumchuck were road houses known as 18 Mile House or 20 Mile House, a reference to its distance from Port Douglas, at the Douglas Road's commencement at the head of Harrison Lake.
An Oblate mission was established in the 1860s and, under direction of the priests, the native community began to build a village at Skookumchuck, about 4 kilometres south of the hot springs. As their community became more settled, the Stl'itl'imx people built a striking Carpenter Gothic church in 1908, which was designated a National Historic Site of Canada in 1981, and remains standing and in use today, the Church of the Holy Cross.
T'sek Hotsprings are managed by members of the Skatin community; camping is available for a fee. Many local families still use the hotsprings, and visitors are asked to respect local family values, be discreet in language and behaviour, and to wait until children have finished bathing before entering the hot tubs.
