Trek the Sahara at Merzouga

Camp among rolling desert dunes.

Dune-bashing in a 4x4, sandboarding, camel rides and a Bedouin-style dinner with falconry as the sun sets over the sand.

The "gateway to the Sahara": camel treks into the dunes and the December festival of horse races and Bedouin poetry.

Dunes, canyons and dinosaur fossils.

Wind-carved chalk mushrooms and icebergs of rock glowing at sunset — camp overnight under the Sahara stars.

Shifting Sahara-like dunes on Venezuela’s Caribbean coast.

White dune fields that fill with turquoise rain lagoons every wet season.

A 70-metre crater of natural gas that has burned since 1971 — camp beside the "Door to Hell" at night.
