Ken Reid Trails is a 3.8 mile lightly trafficked loop trail located near Kawartha Lakes, Ontario, Canada that features a river. The trail is good for all skill levels offers a number of activity options.
There are several trails, lookouts and creatures and much water. Clearly a favourite for me is the boardwalk.
Most of the trails run into and threw one another so you can explore without ever having to go back to a start trail point.
