Here are the urban hiking trails for the Mountain Park and Lake Oswego communities in Oregon. A combination of sidewalks and dedicated paths totally nearly 13 miles, the trail system presents many routes for urban hiking.
Online and offline modes allow detailed, and consistent coverage for the area although the online mode is most useful for navigating the many street intersections and sidewalks. Being an urban location, cell coverage is very good.
Parking, restroom, and water locations are identified on the maps as is your current location, of course.
