Summit Lake Provincial Park, Provincial park in Central Kootenay region, British Columbia, Canada.

Summit Lake Provincial Park is a 6-hectare Class C provincial park on a small peninsula on the western shore of Summit Lake, north of Highway 6 between Nakusp and New Denver. The Nakusp Range of the Selkirk Mountains rises 500 metres above the lake. The park has 35 campsites, some reservable, with basic sanitary facilities.

Summit Lake Provincial Park was established in 1964 and named after the lake it encloses. Long before settlers arrived or the area became a park, the Ktunaxa, Okanagan and Secwepemc First Nations used the surrounding country for hunting and fishing. The park is a Class C provincial park in the Central Kootenay region.

Before settlers arrived, the Ktunaxa, Okanagan and Secwepemc peoples used the area around the lake for hunting and fishing. Today the park is a popular base for anglers and other outdoor sports enthusiasts from the region, who fish the lake for rainbow and cutthroat trout.

The park lies north of Highway 6 on a small peninsula reaching into Summit Lake, between Nakusp and New Denver. It has 35 pitches for tents and motorhomes, some of them reservable, and only basic sanitary facilities. The nearest provincial parks along Highway 6 are Rosebery to the east and McDonald Creek to the west.

The park protects a moist warm subzone of the Interior Cedar–Hemlock Zone, a classification that also covers the toad migration. The lake sits at the foot of the Nakusp Range, which rises about 500 metres above the water.
