Muncho Lake Provincial Park, Nature reserve with jade green lake in Northern Rockies, Canada.

Muncho Lake Provincial Park is a nature reserve in the Northern Rockies, centered around a lake roughly 12 kilometers long with distinctive greenish-blue water. Folded mountain ranges surround the lake, and the park is home to stone sheep and bison roaming the landscape.

Muncho Lake Provincial Park lies within the Muskwa-Kechika Management Area, a protected wilderness region of the northern Canadian Rockies. The park is crossed by the Alaska Highway, here Highway 97, about 240 kilometres west of Fort Nelson. It is classed as a Category II protected area and covers roughly 861 km², taking in the upper Toad River and Trout River valleys around Muncho Lake.

The park takes its name from Muncho Lake, and the lake also gives its name to the small community on its shore. The surrounding land is part of the Muskwa-Kechika Management Area, a protected wilderness region of the northern Rockies. Visitors today share the lake with Dall sheep, mountain goats and woodland caribou, and boat launches at Strawberry Flats and MacDonald campgrounds put anglers on water holding Arctic grayling, lake trout and bull trout.

The park is reached via the Alaska Highway, and the Northern Rockies Lodge offers rooms, cabins, and dining for visitors. Keep in mind this is a remote location where services and supplies may be limited depending on the season.

Muncho Lake reaches 223 m in depth and stays close to 10 °C even in summer, so the lake is cold enough to limit swimming. The park also protects wildflowers across three biogeoclimatic zones, from alpine tundra to spruce-willow-birch forest.
