Florida - At 345 feet (105 m) above mean sea level, Britton Hill is the highest point in Florida and the lowest highpoint of any U.S. state. [4] Contrary to popular belief, however, Florida is not entirely 'flat.' Some places, such as Clearwater, feature vistas that rise 50 to 100 feet (15–30 m) above the water. Much of the interior of Florida, typically 25 miles (40 km) or more away from the coastline, features hills with elevations ranging from 100 to 250 feet (30–76 m) in many locations. Lake County holds the highest point of peninsular Florida, Sugarloaf Mountain, at 312 feet (95 m).
