Plenty of times while skiing across a polar landscape in sunshine, I've thought that if I squinted a bit I could almost fool myself into thinking that I was crossing a spotless white-sand beach.
Now it was time for a reversal. At first glance of our team dragging sledges across white dunes, you might be fooled for a second and need a second look. Ignore the T-shirts and bare feet, and we could almost be back in the polar environment.
These are the sugar dunes of Oman. Lining the coast, just to the south of the Wahiba Sands the dunes are so pale that in bright sunshine they look white. We were all blown away by how beautiful they are.
