Crotch is one of the largest and most accessible lakes in North Frontenac Park Lands. 77 campsites are available and a marked hiking trail through natural wetlands is adjacent to the southwest portion of the lake.
Virtually the entire shoreline of this large lake is Crown land and thus undeveloped and undisturbed. Near the middle of the lake the large peninsulas on both the east and west sides are part of a conservation reserve further protecting the unique environmental features found here.
For canoeing enthusiasts Crotch lake is part of the Mississippi River canoe route.
Access is provided to the north end of the lake off Road 509 near the village of Ompah. Turn south onto South Bush Road and follow it all the way to the lake access point – the last portion of this road is a Crown road. The south end access is from Ardoch Road. Follow the “Crotch Lake Access” sign for the entrance.
