Kennisis Lake is the largest lake in the Haliburton Highlands with a surface area of over 1,640 ha in the area of Ontario just south west of Algonquin Provincial Park. From end to end traveling in a boat, the lake is approximately 23 kilometres long. There is a smaller counterpart, named Little Kennisis Lake, that adds another few kilometres to that distance.

The lakes shoreline lots are almost entirely privately owned, with the newest residences and summer homes being built on the western shore accessible by West Shore Drive. Kennisis Lake is bordered by Haliburton Forest on the north and east, nearby Algonquin Provincial Park to the north, and also a third tract land to the west which is a 24,000 hectare tract of Crown land referred to as the Frost Center Area, after Leslie M. Frost. The lake is accessible through the town of West Guilford on County Road 7, Kennisis Lake Road. This road takes you to the lake and continues along the north shore of Kennisis Lake and ends at the Kennisis Lake Dam, and as a result, there is no through traffic around the lake.

There are approximately 300 lots on the south shore, 632 on the east and north shore, and another 132 lots on the newer west shore. Little Kennisis Lake also has numerous lots (unsure of the number), with nearly 1,000 seasonal and permanent residences on the Kennisis Lakes.
