Marten River is a hamlet of about 100 people 45 kilometres south of Temagami. On the south end of Lake Temagami, the town is largely dependent on forestry and tourism, and is home to a number of lodges and outfitters.
Marten River Provincial Park has camping, hiking, and a replica 19th century logging camp. Every July there is the annual Logging Days Festival. It is also home to the obligatory “some big weird thing” that each town in northern Ontario seems to have – in this case, it is what they claim is Highway 11’s biggest fish, though Nipigon might have something to say about that. (Sorry, Larder Lake, you’re disqualified. You’re not on Highway 11 at all.)
There is a gas station in town, Marten River Outfitters, and a few little places to eat, including the Rock Pine Motel and Restaurant.
There are three lakes near Marten River – Marten Lake, Ingall Lake, and Jumping Caribou Lake. The lake is stocked with fish and there is also hiking at the local crown game preserve.
