Lynch Lake Camp 12 is a backcountry campsite within Frontenac Provincial Park, Ontario, accessible by a roughly two-hour paddle or hike from the Kingsford Dam parking area.

The site is one of four clustered around Lynch Lake, arranged in two pairs: sites 12A and 12B sit close together, as do 12C and 12D on the opposite side of a small knoll.

Sites 12A and 12B each have their own water access points, with 12B offering a slightly more favorable shoreline. Because of the proximity between paired sites, groups looking to camp together would do well to book both sites within a cluster.
