The drive

Highway 203 runs south through the Snoqualmie Valley from Monroe, passing Duvall, Carnation and Fall City, with farmland on the valley floor and the Cascade foothills on both sides. It is a slow, mostly straight road with few bends.

At Fall City the highway meets Highway 202 at a roundabout, and 202 climbs beside the river to Snoqualmie Falls, a waterfall of 268 feet. This drive ends there.

It is 28 miles and takes about 45 minutes. The valley farmland and the falls are the draw more than the curves.
