Big Gull Lake has two public boat launches maintained by the Township of North Frontenac, situated at opposite ends of this roughly 12-mile-long lake in the southern portion of the North Frontenac Parklands.

One launch is located at the end of Thompson Road and the other at 1044 Helen Lane. No road permit is required to access Big Gull Lake, though overnight camping at the launches is prohibited under Township by-law.

The lake offers access to 25 campsites spread across its many islands, all reachable only by watercraft. Anglers use the launches to pursue Northern Pike, Walleye, Largemouth Bass, Smallmouth Bass, and Perch.

The Mazinaw/Mississippi Canoe Route also passes through Big Gull, making the launches a starting point for paddlers as well.
