Officially, Western Sahara is not a country, but a disputed territory on the western coast of Africa, between Marocco and Mauritania. Until 1975, the territory was occupied by Spain; now, it is administered by Morocco. The barren land covered with the Sahara desert is almost uninhabited, and so it is deemed one of the most sparsely populated territories worldwide. A total area of 272,000 km² (105,000 sq mi) is home to just 565,581 people.
Western Sahara is a rather dangerous place to visit because of the wars that took place a couple of decades ago. The hostilities left behind many mines, some of which are still scattered throughout the area. Moreover, Western Sahara is monitored by military forces, which means plenty of checkpoints. If you pass in the vicinity, you will likely be stopped and asked for your documents and permissions.
Travelling in Western Sahara is tough. The area has few settlements, road quality differs greatly from good to horrendous, and all the "desert rules" apply. To stay comfortable during the trip, take care of fuel, water, and warm clothes. Optionally, but desirably, look for a local guide to get you through all the places where there is a chance of hitting a mine.
As for attractions, Western Sahara is not exactly a tourist spot, so you are unlikely to find a great number of exciting options. Instead, spend time exploring the vast desert, get acquainted with resilient people living here, and feel blissfully isolated. Here, on the brink of the world's greatest desert, you can really feel the taste of life away from civilisation.
