Duffey Lake Provincial Park

Duffey Lake Provincial Park is a mountainous protected area along Highway 99 that encompasses roughly 2,000 hectares of terrain centered on an alpine lake. The lake sits at the summit of Cayoosh Pass and is ringed by steep peaks.

This protected area was established in 1993 to preserve a historic travel corridor connecting Lillooet First Nations with the Stl'alt'imx First Nation. The route had served as a vital passage between different regions for centuries.

The location holds deep roots in Indigenous traditions, with communities having used these mountains for hunting and gathering for generations. The landscape reflects this enduring connection to the land.

Visitors can reach the lake by using a gravel boat launch, but should bring their own drinking water as the park has no reliable potable water sources. Plan accordingly when organizing your visit.

This area serves as a vital refuge for mountain goats and grizzly bears within a fragile alpine ecosystem where few other places offer such habitat protection. Rare birds like ospreys and great blue herons are often spotted here.
