Sandboarding is a boardsport and extreme sport similar to snowboarding that involves riding across or down a sand dune while standing on a board, either with both feet strapped in or while standing loose, without bindings. Sandboarding can also be practised sitting down or lying on the belly or the back. It typically involves a sandboard, although it is also possible to use sleds, surfboards, a skateboard deck, or snowboards.
Sandboarding has adherents throughout the world, but is most prevalent in desert areas or coastal areas with beach dunes. It is less popular than snowboarding, partly because it is very difficult to build a mechanised ski lift on a sand dune, meaning participants must walk or ride a dune buggy or all-terrain vehicle back to the top of the dune. On the other hand, dunes are normally available year-round as opposed to ski resorts, which are seasonal.
The sandboard base is much harder than a snowboard, and is built mostly out of formica or laminex with special base materials now being made, that will slide on wet and dry sand. To glide in the sand, the board bottom is often waxed, usually with a paraffin-based sandboard wax, before a run. Afterwards, the bottom of the board may have a lightly sanded look to it. Most terrain sandboards are composed of hardwood ply, while 'full-size' sandboards are a wood, fiber glass, and plastic composite. However, a snowboarding base will sometimes work on steeper dunes as well.
Sandboarding is practised all over the world, with locations available in every continent except Antarctica. The Sandboarding Book lists sandboarding destinations in 30 countries worldwide. A global sandboarding locations map is also available on sand-boarding.com.

Namibia features sand-skiing, which is similar to sandboarding, performed with skis instead of a board. Most of the sand-skiing is performed in the Namib desert dunes around Swakopmund and Walvis Bay. With a special permit it is sometimes possible to sand-ski at the world's highest dunes in Sossusvlei. Henrik May, a German living in Namibia for some 10 years, set a Guinness World Record in speed sand-skiing on 6 June 2010. He reached a speed of 92.12 km/h (57.24 mph).
After some pioneers like Derek Bredenkamp who boarded Swakopmund around 1974, commercial operators in South Africa began offering sandboarding to tourists in 1994. In 2000 the Sandboarding South Africa league was established. Between 2002 and 2004 the South African Sandboarding League held competitions on the Matterhorn Dune located between Swakopmund and Walvis bay. Competition events included dual slalom, boarder cross and big air events. In 2005 and 2006 Alter Action held sandboarding competitions at Matterhorn but the competitions no longer formed part of the South African Sandboarding League during those years. The league collapsed, then the sport was revived again in 2007 with weekly sandboarding sessions in and around Cape Town and Gauteng.
