The dunes are at Jockey Ridge. There are some great things to see. Kitty Hawk is great. But they are all tough to do if you have a heat index of 102 (which they are having right now). Possibly when you go the temps might be a bit more relaxed than they are right now. On a sunny day, sand can get 20 degrees hotter than the air temp (so if it gets to 90, the sand can really burn your feet at 110). Early mornings are great (watch the sun rise! it's beautiful). When the heat builds, it's time to nap inside then hang out by a pool. Have fun!
