Tŝilhqox Biny (Chilko Lake): Remote Wilderness on British Columbia’s Chilcotin Plateau

Why Visit Tŝilhqox Biny

Tŝilhqox Biny, also known as Chilko Lake, sits at roughly 1,170 metres elevation in Ts’yl-os Provincial Park. Its 70-kilometre length and striking glacial hue draw visitors seeking solitude amid the Chilcotin Mountains. The lake’s clear, cold water supports healthy rainbow trout populations while the surrounding subalpine forest and alpine meadows provide habitat for grizzly bears, mountain goats and wolves.

Getting There

Most travellers reach the lake from Williams Lake via Highway 20 west to Tatla Lake, then a network of gravel Forest Service roads that require high-clearance vehicles. The final 30 kilometres can be rough after spring runoff or heavy rain. Float-plane charters from Williams Lake or Bella Coola offer a scenic alternative for those who prefer to avoid the long drive. No scheduled public transit serves the area, so independent transport or guided tours are essential.

Things to Do

Fishing

Anglers target large rainbow trout and occasional bull trout from shore or by boat. The Chilko River outlet is a favourite drift-fishing spot; provincial angling regulations apply and a licence is required.

Paddling and Boating

Kayakers and canoeists enjoy multi-day trips along the eastern shore, camping at designated backcountry sites. Motorboats are permitted but must respect no-wake zones near the park’s southern campgrounds.

Hiking and Wildlife Viewing

Trails such as the Tŝilhqox Biny Trail and the steeper ascent to Potato Mountain offer panoramic views. Early morning and dusk are best for spotting wildlife along the shoreline.

Best Time to Visit

July through early September offers the most reliable road access and comfortable daytime temperatures. Mosquitoes peak in July; September brings quieter conditions and possible early snow at higher elevations.

Nearby Destinations

Continue west on Highway 20 to the dramatic descent into Bella Coola or detour north to the smaller lakes of the Chilcotin Plateau for additional paddling and angling opportunities.
