Sandboarding is a boardsport and extreme sport similar to snowboarding and iceboarding. 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.
Lucky Bay, about 30 km south of Kalbarri, in Western Australia, is another sandboarding hotspot. Sandboarding Tours are offered in the area.
The Stockton dunes, 2.3 hours north from Sydney. Stockton Bight Sand Dunes system is up to one kilometre wide, 32 kilometres long, and covers an area of over 4,200 hectares. The massive sand dunes climb up to 40 metres high. Located only minutes from the centre of Nelson Bay, it is the largest sand dune system in Australia.
Sandboarding sites in Egypt include the Great Sand Sea near Siwa Oasis ? ? in Egypt's Western Desert, the Qattaniya sand dunes (1.5 hr drive on/off-road from Cairo), El Safra ? and Hadudah dunes midway between Dahab and St. Catherine in Sinai.
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. In the area, they use two different sand-boarding styles, the "Lie Down", where the rider lies upon a special made board and slides headlong on the sand dunes and "Stand Up Boarding", where the techniques are quite similar with those of snowboarding.
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.
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.
After some pioneers like Derek Bredenkamp who boarded Swakopmund around 1974, commercial operators began offering sandboarding to tourists since 1994. In 2000 the Sandboarding South Africa league was established. Sandboarding competitions started in 2001 when SA camps were held in 2002 up and until 2004. The league collapsed, then the sport was revived again in 2007 with weekly sandboarding sessions in and around Cape Town and Gauteng.
Sand Master Park, located in Florence, Oregon USA is the world's first sandboard park with 40 acres (160,000 m2) of private sculpted sand dunes and a full-time pro shop. Dune Riders International is the governing body for competitive sandboarding worldwide and sanctions three events each season at Sand Master Park.
Great Sand Dunes National Park and Preserve near Alamosa, Colorado welcomes sandboarding on the tallest dunes in North America.  Sandboarding and skiing are permitted anywhere on the dunefield away from vegetated areas.  Great Sand Dunes National Park does not rent sleds or sandboards; these may be rented or purchased at two retailers in the San Luis Valley in which the park is located.
Amothines is a small desert five kilometres from Katalakkos village in Limnos, Greece. There are many sand dunes there, where people can practice sandboarding.
In the North East region of the United Kingdom, there is a small beach at Seaton Sluice where people can sandboard. This is a good alternative to sledding, as there is insufficient snow to support sledding there, even though the UK has a cold climate, with cold winters and cool summers.
