Ts’ilʔos Provincial Park
About This Park
Ts’ilʔos (pronounced “sigh-loss”) Provincial 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 provincial 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. 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.
Established Date: February 12, 1994
Park Size: 233,240 hectares
Note: Ts’ilʔos Park is co-managed through a Memorandum of Understanding between BC Parks and the Xeni Gwet’in First Nations Government.
Know Before You Go
- Ts’ilʔos Provincial Park is remote. Visitors must be self-sufficient and competent in order to deal with the challenges of the outdoors. BC Parks does not provide rescue services.
- Only experienced boaters and kayakers should attempt Chilko Lake, due to the unpredictable winds and other challenges such as high waves, icy waters, and a shortage of safe landing areas. Canoeing on Chilko Lake is not recommended.
Ts’ilʔos Provincial Park is located in a relatively undeveloped and isolated part of the Chilcotin. As the crow flies, the park is approximately 160 km southwest of Williams Lake, or 250 km north of Vancouver. There are two main vehicle access routes into the park, and two campgrounds, one at the end of each route. Both routes take 4 to 6 hours from Williams Lake, though travel time varies considerably depending on weather conditions. Roads are rough, and conditions vary considerably. Drive carefully and with lights on. The nearest communities to the park are Nemiah Valley, Hanceville, Tatla Lake and Williams Lake.
No scheduled flights serve the park. Several airstrips are located outside the park boundary; a Park Use Permit is required for commercial air access within the park.

The backcountry of Ts’ilʔos Park is recommended for experienced travellers only who are equipped for trail finding, first aid, and survival situations. Hiking routes are not maintained and there are no facilities.
In order to meet budget targets, trail maintenance has been reduced on the Yohetta/Tzchaikazan Loop Trail in this park. Although this trail will remain open, users may encounter fallen trees and/or trail wash-outs. Extra caution is advised.
For your own safety and the preservation of the park, obey posted signs and keep to designated trails. Shortcutting trails destroys plant life and soil structure.
There is horseback riding at this park, although trails are neither maintained nor marked.
