Gull River is in the Algonquin Highlands, part of the Trent River and Lake Ontario drainage basins, and flows from southern Algonquin Provincial Park to Balsam Lake on the Trent–Severn Waterway. The towns of Minden, Norland, and Coboconk sit along Gull River as well as several towns where the Gull River widens into lakes.
It is approximately 2 hours drive from Toronto and approximately 50 minutes from Lindsay.
The Gull River flows out of Gull Lake, travels south to feed into the north end of Shadow Lake. It is dam controlled and offers opportunities for white water kayaking. Parts of the river hosted the the Canadian stop on the World Cup Kayak Slalom tour in both 1991 and 1993.
The river’s lowest and southernmost lake, Silver Lake, lies upon the boundary line between the Precambrian Shield, and the Limestone topography which lie south of it. The lakes and rivers north of Silver Lake twist and wind between the highlands and valleys created by the retreating glaciers at the end of the ice age. The result is the spectacular and pristine wilderness that has earned Highway 35, that passes through the drainage basin, a reputation as one of the most scenic highways of Ontario.
