Hot Sands

Surface temperatures on the dunes may reach 150 degrees F on summer afternoons. To avoid heat exhaustion and burned feet, plan to hike the dunes in early morning or evening in summer months. Hot sand can blister or even cause second-degree burns on bare feet, the tops of feet (when wearing sandals), and any exposed skin that comes in contact with the hot sand. Wear closed-toe shoes when hiking on the sand. Take sunscreen, as skin burns easily at this high elevation (8,200 feet/2,499m at the visitor center). Remember your pet's feet are sensitive to burns, too. Avoid hiking on the dunes mid-day in summer when the sun is shining.
