The South Canol meanders 220 km (143 miles) from Johnsons Crossing (Alaska Hwy) to Ross River (Campbell Hwy). There are no services along the road.
There is one territorial
campground and several recreation sites.
For additional information about the South Canol Road (external links):
After a quiet night at Squanga Lake Yukon gov't campground (km 1316 Alaska Hwy),
we backtracked 20 km to Johnsons Crossing (km 1296).
There is also a commercial campground at Johnsons Crossing.
I asked about conditions on the South Canol. Turns out a fellow buying coffee was responsible for road maintenance in the area and he told us there was some freshly graded areas, some recent repair of washouts and the road was in reasonable condition.
So we ventured north on the South Canol Road.

The road was good gravel and varied from one to two lanes wide. Initially the scenery was not overly spectacular; however the fall colors added emphasis to the sights.

Some of the vistas were very nice. The landscape was expansive.

The bridges were single-lane. Generally the wood decks were in good condition.

The road was in better condition than we anticipated. The miles were rolling by quickly. There were few signs along the road and many places to pull over to relax.

Quiet Lake Yukon Government campground (km 76) was quiet. The campsites did not have a view of the lake. We camped at the boat launch. During our two day stay, no one launched a boat.

Steve decided he wanted to soak in the water. We weren't sure how long it would be before the RV's fresh water tank could be refilled so he took advantage of the water in the lake.

The campground seems to also get use in winter. The picnic shelter had a sign on it.
