National Park Service (NPS) hiking guidance calls for sturdy shoes, sun protection, and at least half a gallon of water per person for every four hours of hiking. Heat, humidity, exposed rock, loose footing, sudden rain, and a steep return can matter more than mileage.
Reef Bay descends into a greener interior and requires the energy to climb back. Ram Head crosses drier, open terrain where shade is scarce. Cinnamon Bay offers shorter trail choices. Use the official description for the exact route, then compare its demands with the day's temperature and the least experienced walker.
Cell coverage is not a rescue plan. Carry the map, tell someone the route, start with enough daylight, and turn around before drinking water runs low or weather and footing worsen.
