You can buy tickets and rent a bike from the Lookout Ski Pass Area, or drive on to Exit 5 in Montana to access the East Portal parking area. The Hiawatha Trail is a bike trail converted from an old railroad. The best part is that it's a 15 mile, downhill ride through tunnels and across trestles. At the bottom a shuttle will drive you and your bike back to the parking area. #biking #historical #rail-to-trail
