Spring and fall
Multiple campgrounds on the roughly paved road to the falls CG. Recommend parking outside and scouting. Not all are RV friendly. S. Umpqua Falls CG is on opposite side of road from falls, but you can hear them. Great large sites, easy in/out although scout first. No water, but clean vault toilets and trash cans everywhere. No cell service which benefits the campers whom do not play by the rules. M-F are very quiet. Great wilderness hiking nearby.
