I am one of a few Swedish who like more the desert than high mountains like Atlas etc. Erg Chebbi in Morocco is one of my favorite places, especially a little village Khamlia where it is still silent, not so many hotels, therefore tourist neither, really nice place. You can sit there only, talk with locals, admiring the landscape, sunrise/sunset when the all changes color from yellow to pink. One other favorite place now became Wadi Rum in Jordan, fantastic place and people. Amazing it is.
Other favorite places is rain forest, contrast to the desert. And even if I have been on other continents so Africa is definitely my favorite one.
Morocco, Italy, Spain, West Africa, Jordan
