This is a spectacular route with great views and variety, skirting the two provinces. Start at centrally located Alexandra bridge and cross the pedestrian friendly path over to Hull on the Quebec side. Take Voyageurs Trail — part of an incredible 10,000 mile Trans Canada Trail (you’ll see signs also for ‘route verte’) heading west, passing the Canadian Museum of History and the convention center. You’ll reach Parc Mousette at about 4 miles. Cross back over to Ottawa on the mile-wide Champlain Bridge (also known as the Island Park Bridge), over Bate Island and Riopelle Island, with great views of the river and rapids. After crossing the bridge, head ~4 miles back to the start along the Ottawa River Trail (also referred to as the Trans-Canada Trail). There are some cool rock sculptures just past mile 6 and then the important National Capital landmarks toward the start/end point.
