The climb of Mt. Bachelor's south side is probably the less scenic of the three climbs on Mt. Bachelor, but it serves as an important link for cyclists doing the 52-mile loop around the mountain.
The 11-mile, 1,574-ft. climb ascends Forest Road 45 from its intersection with Forest Road 40 a few miles west of the Sunriver resort. The top of the climb is the intersection with the Cascade Lakes Scenic Highway (5,932 ft.), where cyclists can opt to either turn left to climb to the Mt. Bachelor Ski Area at 6,317 ft., or turn right for a rapid descent to the city of Bend (3,629 ft.).
Forest Road 40 has a broad, smooth shoulder, and very little traffic.
The full loop around Mt. Bachelor (52 miles, 2,800 ft.) combines this climb (Forest Road 45) with the Cascades Lake Scenic Highway and Forest Road 40. Water is likely available at the various campgrounds along the loop, but other services are largely nonexistent.
