The Coal Mines Trail is built on an old railroad spur of the Northern Pacific Railway that once served several mines. Look for interpretive signs along the way that identify historical sites. The trail lies 80 miles east of Seattle and runs through three small towns.
From its southern end in Cle Elum, the trail follows a tree-lined route paralleling Crystal Creek while traveling northwest to Roslyn, where the popular TV show Northern Exposure was filmed. Here, trail users can visit the Roslyn Museum (203 W. Pennsylvania Ave.), about a block from the trail, to learn about the town's mining past.
Outside the city, the trail continues through the trees until reaching its end at Ronald.
At the trail's southern end in Cle Elum, parking is available at Flag Pole Park (corner of W. First Street and Stafford Street).
Easy trail and farily flat which would be good with kids. Trail extends from Cle Elm to Ronald with Roslyn about have way. Some mountain biking trails available near the Roslyn. When entering Roslyn the tail end on the east side and you have to ride through town on Washington ave 2 blocks and pick up the trail on the west side which is only 2 blocks away. If you get lost just head to the town pub and ask directions after refueling.
