9. The Black Desert, Egypt

The Black Desert, Egypt

While everybody heads to Cairo Museum or Sharm El Sheik Red Sea resorts, go to see the black pyramidal mounds that emerge from the yellow desert sands like alien structures some 30 miles from Bawiti.

Close by you'll find dazzling white desert sands, giving you a good idea what alien worlds on other planets must look like.
