Oastler Lake Provincial Park, Provincial park in Parry Sound District, Canada

Oastler Lake Provincial Park is a protected recreation area situated along the Boyne River and Oastler Lake with waterfront access. The grounds feature camping facilities and offer opportunities for canoeing and fishing throughout the landscape.

The sources document no founding date or designation year for Oastler Lake Provincial Park, so its establishment history is not recorded here. What is known is its setting: a 32-hectare recreation-class park in Seguin, Parry Sound District, on Oastler Lake where the Boyne River enters from Otter Lake. It lies along a former alignment of Highway 69, now named Oastler Park Drive, and the nearby town of Parry Sound is about 6.6 km to the northwest.

Fishing enthusiasts spend time at the lake catching rainbow trout, pike, and bass throughout the season. It is a popular pastime for both locals and visitors exploring the waterways.

The park lies along Oastler Park Drive, a former alignment of Highway 69, about 6.6 km southeast of Parry Sound. The Boyne River enters Oastler Lake from Otter Lake at the park's shoreline. The grounds sit roughly 203 metres above sea level in flat terrain, so walking between the lakefront and camping areas is easy.
