South of Crater Lake, the byway continues down Oregon Route 62, with Mount Scott on the east, to Fort Klamath, whereupon it heads west on Weed Road to Sevenmile Road, then south on West Side Road along the edge of the Upper Klamath National Wildlife Refuge and Upper Klamath Lake. The byway then passes Mount McLoughlin on the east as it joins Oregon Route 140 to Klamath Falls.
