Of course there can't be many people who don't know what snowboarding is, but how about sandboarding? The basic principle behind the two sports in the same; start at the top of a slope and use a board to get you to the bottom. But whereas snowboarding is practised on freezing cold snowy mountain tops, sand boarding takes place on sand dunes by sunny beaches or in the desert. It's popular in many countries, including Australia, Namibia and South Africa.

The quickest way of getting to the bottom involves standing with both feet on a board and weaving from side to side while trying not to fall off. If this sounds a little bit adventurous you could always just get on your stomach and slide down. Either way, it's a lot of fun! However, don't forget to keep your mouth closed.
