Around the country old train routes are being turned into multi-use paths. I've been on a bunch of them, but few compare to the Trail of the Couer d’Alenes. This decommissioned train route follows a backcountry route across northern Idaho, from Plummer, a prairie town near the Washington border, to Mullan, a mountain town near the Montana border. In between it crosses a state park, a lot of lake, river, and marsh, the cute town of Harrison, and the historic and pretty Silver Valley. It’s open to walking, skiing, in-line skating, and biking, with several campgrounds along with way and a few places to buy provisions. We've section biked a few parts of the trail and loved it – the best part is the super scenic jaunt along the shores of Lake Couer d’Alene and across it on the Chatcolet Bridge. Although the trail climbs and dips from plateau to valley to mountain, since it’s a railroad grade it’s never steep – actually, it’s usually impossible to tell you are climbing or descending except in a few places.
