Straddling the county line between Victoria and Cape Breton counties, the park is located in the communities of Dalem Lake and New Dominion and is adjacent to the communities of Big Bras d'Or, Millville and Black Brook.
The 74 hectare picnic park is managed by the provincial Department of Natural Resources and completely surrounds Dalem Lake, a small lake that is almost perfectly circular - it sometimes also referred to by locals as "Round Lake". The lake has a small sand beach suitable for swimming and is popular for paddling such as canoeing and kayaking. The park also permits licensed trout fishing. There is a 1 kilometre hiking trail encircling the lake.
