Allison Lake Provincial Park, provincial park in British Columbia

Allison Lake Provincial Park is a small park in the Regional District of Okanagan-Similkameen beside a quiet lake bordered by trees. It contains camping sites shaded by mature Douglas fir trees, a sandy beach on the southern shore, a picnic area with ten tables, and a walking trail that runs about 5.4 kilometers from the camp area to homes at the lake's north end.

Allison Lake Provincial Park was established on July 26, 1960, covering 23 hectares beside Allison Lake, 28 kilometres north of Princeton. It was created mainly as a recreation area for camping, swimming and fishing, and the park today is mostly aspen.

The park's name comes from Allison Lake, the body of water it borders. The surrounding forest is mostly aspen, as recorded in the park's own description, rather than the conifers of the wider valley. Visitors reach the park by road from Princeton, 28 kilometres south, and the lake sits at 874 metres above sea level.

The park sits about 28 kilometers north of Princeton on Highway 5A and is straightforward to reach. There are no showers or stores on site, so visitors should bring enough water and supplies and expect basic facilities like pit toilets and water taps.

Allison Lake Provincial Park covers 23 hectares at 874 metres above sea level, in a valley near Tulameen, about 19 kilometres to the southwest. The surrounding country is nearly uninhabited, with fewer than two people per square kilometre, and the forests around the park are mainly coniferous.
