Sandboarding is a boardsport and extreme sport similar to snowboarding and . It is a recreational activity and takes place on sand dunes rather than snow-covered mountains. It involves riding across or down a dune while standing with both feet strapped to a board, though some sandboarders use a board without bindings. Sandboarding can also be practised sitting down or lying on the belly or the back. Typical sandboarding equipment usually involves a sandboard (although some sandboarders use sleds, surfboards, possibly a skateboard deck without wheels, or snowboards), bindings, and possibly boots.
Sandboarding has adherents throughout the world, most prevalently 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, and so 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 for this sport. 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, while 'Race Base' tends to polish smoother and glossier with use. 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.
