The 296km Ottawa Valley Recreational Trail is a multi-use corridor stretching from near Smiths Falls to just shy of Mattawa, passing through Lanark County, Renfrew County and Papineau-Cameron Township. This is the repurposed former Canadian Pacific Railway line. The current open section stretches from Petawawa to Arnprior (also known as the Algonquin Trail) and then heads south towards Smith Falls.  The trail passes through many communities along the way, which offer parking, restaurants and other tourist landmarks along the way.   

Beautiful route into the mountains and then down to the coast of Koh Phangan. First section clockwise is on paved, steep road and then transitions into rugged dirt road terrain. The heat in May should be taken seriously as the route is very exposed and there is little water access the second half of the route. Heat is by far the most challenging aspect of this route so prepare accordingly! Spectacular views along the top with no road or foot traffic along seemingly deserted roads and trails the second half of the route.
