An unnamed eastern tributary flows into Spoilcane Creek a hundred feet downstream from Spoilcane Falls. A short distance up this tributary lies a picturesque, stairstepping waterfall, known as Phil's Sister Falls because it acts as a sister waterfall to Spoilcane Falls. About 35 feet high, this waterfall is especially scenic in wet weather when a strong flow is tumbling down the stairstepping ledges. During those times, Phil's Sister Falls is worth the quick bonus bushwhack when already visiting Spoilcane Falls.
