Following seaside lunch, the second part of our day was even more an adrenaline rush. A half hour south, we passed through Ica to the natural sand dune formations, towering mountains of sand of Huan.... (sp?) and a desert Oasis below. On board our 9-person "buggy" (say " boo-gey" for true effect), we climbed up and over and around the hills and valleys at warp-speed - YAHHOOO! Great fun. Atop the first "small" hill, we took out the sand boards, and had a go at sliding to the bottom... Katie loved it, and Derek tried it snow-board style, zip zip down the 70 degree slope to the bottom, and back up again (harder to climb sand than snow).
