Cycling is a favorite sport in the Northwest, especially in Portland, which features over 260 miles of bike lanes and trails. One of the most popular is the 16.5-mile Springwater Corridor Trail, a paved surface, multi-use trail that runs along a former rail line through part of the city, past Powell Butte Nature Park, and then through meadows, woodlands, and natural wetlands to Gresham.
The Waterfront Bike Loop begins at Waterfront Park and runs along the west side of the Willamette River until crossing the Steel Bridge. Continuing on the east side of the Willamette via the Eastbank Esplanade, the trail connects with the Springwater on the Willamette Trail, winding its way between Oaks Amusement Park and the Oaks Bottom Wildlife Refuge before crossing the Sellwood Bridge and returning to Waterfront Park.
The Marine Drive area of north Portland offers several bike paths along the Columbia River and crossing the river into Vancouver, Washington. A bike map is advised to see these various routes.
A list of local bike trails and excellent maps can be found at the City of Portland Office of Transportation.
