What is a chott / sebkha (salt flat) in Morocco?

A chott (also written sebkha for the smaller ones) is a salt flat — a low, flat basin with no outlet where rainwater collects, sits in a shallow shimmering sheet, then evaporates under the desert sun and leaves a hard, blinding-white crust of salt and minerals behind. Through most of the year it is bone dry and cracked into a mosaic of pale tiles; for a few weeks after rain it becomes a mirror-flat lagoon. Knowing the difference between the two seasons is the whole trick to enjoying one.

The truly enormous chotts — the famous Chott el-Jerid — sit just across the border in Tunisia, but Morocco has its own scatter of sebkhas through the desert south and along the pre-Saharan plains. They are not headline destinations the way the dunes are, but you pass them, and when you do they stop the car. A dry sebkha is a sheet of dazzling white that hurts to look at; a flooded one becomes a perfect mirror that doubles the sky and the distant mountains.

The atmosphere out on a salt flat is genuinely strange. There is no vegetation, no shade, no scale — just a flat white plane that plays tricks with your eyes, throwing up shimmering mirages of water that is not there. The crust crunches under your feet, and the heat reflecting up off the white is fierce. People find it eerie and beautiful in equal measure; it is one of the few landscapes that feels truly empty, like standing on a blank page.

For travellers, the honest note is that a chott is a passing wonder rather than a destination you build a day around. I point them out, we stop for photographs — the mirror reflections after rain are spectacular — and we move on. The one real caution is never to drive out onto a flooded sebkha; under the salt crust the mud can be soft and bottomless, and vehicles do get swallowed. Admire it from the firm edge, get your reflection shots, and leave the surface to the salt.
