Take Hwy. 37 just north of Libby to the dam. Stop at the visitors center then head north on the west side of the lake to the bridge just below Rexford. Cross the bridge back to Hwy. 37 and head south to complete the loop. If you have some extra time, head north on Hwy. 37 off the bridge to the quaint little town of Eureka, a town built on the timber industry. After knocking around the town, head back south on Hwy. 37 to complete the loop.
