The 40-Mile Loop Trail is a century long effort to build a comprehensive trail
system
through
and
around
Portland.
The planned loop trail has lengthened
to
more
than
140 miles to include all of Multnomah County and to connect more than 30 parks. The
trail connects parks and locations along the Slough and along the Columbia, Sandy,
and
Willamette
Rivers
and
Johnson
Creek in
an almost continuous loop.
