Western Uplands Backpacking Trailhead

Highlight • Trail

This trailhead serves as the main access point for the Western Uplands Backpacking Trail, and a network of backpacking loops that range from 32 to 88 kilometres. Located just off Highway 60 next to the Oxtongue River Picnic Ground, you'll find plenty of parking, washrooms, and picnic areas, along with information about the trails. A valid permit is required for all visitors to Algonquin Provincial Park. A day use permit provides access to the trails and day-use areas from 7:00 a.m. to 10:00 p.m., and if you're planning a backpacking trip, you’ll need a backcountry camping permit.
