A geologic fault, with mafic, metavolcanic bedrock to the west, and sedimentary and volcanic rock to the east, has determined the winding course of the Larder River. The river valley is lined with silt, sand and gravel deposited by glaciers, as well as clays derived from lake or floodplain sediment. Within the 2,500-hectare Larder River park, a 30-kilometre stretch of the river is preserved.
Park Facilities and Activities: There are no facilities for park visitors, but the river invites canoeing, fishing and swimming. Hike along its banks and enjoy the many views of rapids and waterfalls.
NOTE: Much of the Larder River features wild, white water—to be challenged by experienced canoeists only.
Location: Thirty kilometres east of Kirkland Lake, near the Quebec border. Water access point is north of Highway 569 at the southern end of the park.
