This loop crosses the Cascade crest on two passes near Sisters, Oregon. The McKenzie Pass road (SR-242) climbs through a vast, jagged lava flow to the Dee Wright Observatory, a shelter built entirely of lava rock with windows framing the surrounding volcanoes. The Three Sisters and Mount Washington stand close at hand; the narrow McKenzie Pass road is closed by snow much of the year.

What is a National Scenic Byway?
National Scenic Byways are roads recognized at the federal level for at least one outstanding quality — scenic, natural, historic, cultural, archaeological or recreational — that gives travelers a reason to seek them out rather than just pass through.
