The Track & Tower Trail in Algonquin is approximately 10.0 km when the look-out look is added to the standard 7.5km trail. This trail took about 3 hours to complete. The lookout is one of my favourites in Algonquin Park and this trail takes you through wooded and lakeside areas of the park. There are many sections of the trail that are steep inclines up and down and I would rank this as a difficult day trail.
