River Valley Trail Maps which can be downloaded onto portable devices.
You can walk from the westside to the eastside of Edmonton along both side of the Saskatchewan River. There are frequent vehicular and pedestrian bridges allowing you to break up the distance into short 1-2 hour loops. The following walk starts on the westside near Fort Edmonton and crosses the newly built Fort Edmonton Footbridge. The City of Edmonton provides excellent online River Valley Trail Maps which can be downloaded onto portable devices.
Another excellent walk from Pacific Playgrounds is the trail along the ocean from Oyster River to Salmon Point Resort. Cross the river on the bridge by the Fisherman’s Pub and take the trail that starts in the Oyster River Nature Park. The return walk is a little under 8 Km. and takes a little less than 2 hours. There are pubs at both ends of the trail.
