Suplhur Springs is a sweet little side road. This one is really narrow. This is a local community access road so my suggestion is 40km/h max, and watch out for gravel. There is littlebit here and there laying around from the side roads. The nicest part of this road is probably the little river that runs right along the road. It's a nice run through a very peaceful and shaded area. Hear the natures of sound all around, as long as your bike is not too loud. Runs between Effingham and Rolland Rd.
