Lac La Hache Provincial Park, Provincial park in Cariboo, Canada.

Lac La Hache Provincial Park covers 28 hectares on the Chilcotin Plateau, split by Highway 97 about 54 km south of Williams Lake. South of the highway lie the lake access, picnic area and parking; north of it sits the campground. An old-growth stand of Douglas-fir shades the sites, with trembling aspen, lodgepole pine, pinegrass, bunchberry and prickly rose below.

Lac La Hache Provincial Park was established on 13 March 1956 together with 24 other parks; its boundaries were redrawn several times, most recently in 2004, when it was enlarged to its present 28 hectares and made to include part of the lake. Long before settlers arrived, the area was hunting and fishing ground for the Tsilhqot'in and Secwepemc, and remains of pit houses are still found nearby. European access came with the Cariboo Gold Rush, when the Cariboo Road ran through the district and its route is partly followed today by Highway 97.

The park lies within the traditional hunting and fishing grounds of the Tsilhqot'in and Secwepemc First Nations, who used the area long before settlers arrived. Remains of their pit houses, semi-subterranean dwellings, can still be found in the surrounding district.

The park is split by Highway 97: the campground with 83 reservable and first-come sites lies north of the road, while the lake access, picnic area and parking are south. Pit toilets are available; bring drinking water and food. Boat ramps make it popular with watersport users.

The surrounding forest includes Douglas fir, trembling aspen, lodgepole pine, pinegrass, and bunchberry in a mix that creates varied woodland character. This plant combination is typical of the local ecosystem and changes appearance with the seasons.
