Either in Libya or Algeria. I've been to Algeria, Tunisia & Morocco but the terrain varies so much and Dunes get shifted with the wind that the size of any particular dune would change. I remember seeing a thread on ADVRider about a bunch or dimwits trying to fang it up a massive dune, but surely it was in the States. The thread did make for some entertaining reading however.

Wikipedia:
It depends on the type of sand dune.

There are three contenders for the title of the world's biggest sand dune, and it depends upon the context - whether one means the highest in actual sand dune size, or the highest above sea level. According to some sources, the world's highest sand dune is the Cerro Blanco dune in the Sechura Desert, Nazca, Peru. However, according to the Namibian Ministry of Environment & Tourism, the highest dune in the world is called Big Daddy, or Dune 7, and is one of the Sossusvlei dunes in the Namib Desert. However, according to the website link below (Duneguide), the highest sand dune may well be the humble Mt Tempest on Moreton Island, just off the coast of southern Queensland, Australia. The second largest sand mass in the world, Mt Tempest reaches 280m above sea level.

The world's highest stationary dunes are the Badain Jaran dunes in the Badain Jaran Desert within the Gobi Desert in inner Mongolia.

The longest parallel sand dunes in the world are in Australia's Simpson Desert. Consisting of over 100 dunes, they run north-south, with some stretching as far as 200 km.

The largest crescentic sand dunes in the world are located in the Taklamakan Desert of China. These dunes have an average crest to crest width of over three kilometres.

As far as the Sahara is concerned:
The biggest sand dunes are in Algeria in the Sahara Desert. They are up to 430m (1,411 ft) high, nearly three times the height of the Greatest Pyramid of Cheops in Egypt or nearly or twice as high as Canary Wharf.

Membership - help keep us going!

Horizons Unlimited is not a big multi-national company, just two people who love motorcycle travel and have grown what started as a hobby in 1997 into a full time job (usually 8-10 hours per day and 7 days a week) and a labour of love. To keep it going and a roof over our heads, we run events all over the world with the help of volunteers; we sell inspirational and informative DVDs; we have a few selected advertisers; and we make a small amount from memberships.

You don't have to be a Member to come to an HU meeting, access the website, or ask questions on the HUBB. What you get for your membership contribution is our sincere gratitude, good karma and knowing that you're helping to keep the motorcycle travel dream alive. Contributing Members and Gold Members do get additional features on the HUBB. Here's a list of all the Member benefits on the HUBB.
