Rock Lake is a lake located in Algonquin Provincial Park in Haliburton County, Ontario, Canada.
Rock Lake features a campground with 121 sites at the north end of the lake which is accessible from Highway 60 via a gravel road.[3] Algonquin Park also maintains about 20 designated campsites around the lake that are accessible by boat as well as several portages to neighbouring lakes.[4] The lake is popular with canoeists and kayakers. Motors boats are permitted with a limit of 20 horsepower. About 20 cottages on long term leases are found on the shores of Rock Lake. The 5 km Booth's Rock hiking trail overlooks the Lake.[5]
The Madawaska River flows into Rock Lake from the north and out of it in the southeast. The South Madawaska River enters Rock Lake from a long bay in the southwest.
Prehistoric camp sites as well as cairns and petroglyphs have been found around the area.[6] [7]
