HIGHLIGHTS: Whiteside Mountain is located a short distance from the communities of Cashiers and Highlands, North Carolina and the summit is a popular day-hiking destination for the local residents. At 4,930 feet, Whiteside Mountain has spectacular views looking east toward Blackrock, Yellow, and Terrapin mountains. The well-marked, moderately difficult loop trail that traverses its summit offers views to the Chattooga River Valley, and gains about 500′ in elevation from the parking area. Sheer 750′ cliffs drop to the valley floor from the ridges along Whiteside Mountain, and are among the highest in Eastern America.
