Ts’ilʔos (pronounced “sigh-loss”) Park comprises rugged mountains, clear blue lakes, glaciers, alpine meadows, and waterfalls. It is bordered by the rugged peaks of the coast mountains to the west, and the dry interior plateau to the east.
The diversity and contrast in landscapes and vegetation are a result of a rainshadow effect on the east side of the mountains. While the northern and eastern portions of the park are relatively dry, the south end of Chilko Lake is characterized by moist areas of the coastal western hemlock zone.
The park was established in February of 1994 as a wilderness area set aside to protect vegetation, wildlife and fish habitats, cultural values, and special features. Ts’ilʔos Park is co-managed through a Memorandum of Understanding between BC Parks and the Xeni Gwet’in First Nations Government.
The diverse ecosystems in the park remain largely undisturbed by human activity, making this park an ecologically significant area in the province. Chilko Lake, the largest, natural high-elevation freshwater lake in Canada, dominates the park.
Stunningly beautiful, due to its blue-green hues and dramatic mountain backdrops, Chilko Lake is popular with boaters, kayakers, and anglers. Backcountry hiking and camping is also a cornerstone of the recreational opportunities offered by this remote park.
