Hobe Mountain is the highest natural point south of Lake Okeechobee, rising 86 ft. above sea level on ancient sand dunes. A 10-minute walk to the top of the Hobe Mountain Observation Tower offers views of the Atlantic Ocean, Intracoastal Waterway, and the park’s full expanse, while the route through the Sand Pine Scrub, a vanishing plant community, reveals changes in terrain and elevation.
