Tinfou'd claim to fame is being the very first place along the Draa Valley route where stone desert cracks open to sand desert. It's appearance is quite wild and feels unrealistic: Out of the barren ground suddenly a few hundred metres of warm, yellow sand waves pops up. They lie over the stone desert, and many tourists coming out here ask whether somebody dumped the sand here in order to create the tourist trap that Tinfou definately has become. In small scale of course. The truth is of course that is real nobody would drive thousands of cubic metres of sand around in the Sahara desert. Many other places on the edge of humanity in the desert, the first sand dunes pops up out of nowhere. Merzouga further east is a good example of that.
