I really want to visit New Zealand, a land that seems filled with wonders. There's a beach on the North Island where geothermal energy heats the sand. It can get as hot as 147° F, so visitors often dig hot tubs into the beach. View more pictures and a video at the link.

You just dig a hole and the water is so hot that you cant be inside the hole for long time.
