Hailed as a conservation success story, Namibia takes its name from what’s believed to be the world’s oldest, and certainly one of its most impressively deserty deserts. Along with its magnificently adapted rhinos, lions, and elephants, and the austerely haunting Skeleton Coast, where uncompromising desert flows directly into equally indomitable ocean, Namibia is famed for its sand dunes, the highest in the world. A number of giants vie for top spot, but the sandy monarch of all is probably Big Daddy, which, at 1264 feet is 28 Shaquille O’Neals higher than the Chrysler Building.
