Knapp Coulee

Tour follows the southwestern shore of Lake Chelan and passes many orchards. Between Lake Chelan and the Columbia River the highway winds its way through coulees. Large boulders and odd stratifications are numerous in the coulees.

At Knapp’s Hill the tour passes through a 600 feet long, 26 feet wide, and 21 feet high tunnel, which eliminated the dangerous cutbacks and steep grades of the old road that wound above.
