The 468-hectare McDonald Creek Provincial Park stradles Upper Arrow Lake and the combined shoreline on the east and west encompasses over 6 km and is complimented with natural sandbars and coves. The Arrow Reservoir bisects McDonald Creek Provincial Park and protects lakeshore riparian habitat on the east side and forested upland habitat on the west side.
With so much water in this part of the West Kootenays, the fish are never far away. Fishing for kokanee, dolly varden, and rainbow trout is good in Upper Arrow Lake, accessible from McDonald Creek Provincial Park. The boat launch is located at the south end of the park, accessed by turning turn left at the park entrance. This concrete plank, singlewide ramp is only useable during high water.
There are 38 vehicle accessible sites in the park including 3 doubles. Four of these sites have tent pads. There are no pull through sites however the campground has an even mix of small to large sites and can accommodate large recreational vehicles. The park offers services during the peak season from May to September. Campsite reservations are not accepted.
McDonald Creek Provincial Park is located in the kootenays region of British Columbia, 6 miles (10 km) south of Nakusp.
