Mauritania places 90 percent of its territory inside the Sahara Desert. The Richat Structure occupies a circular geological formation 40 kilometers in diameter in the Adrar Plateau. This bulls-eye of concentric rings contains sedimentary rock layers uplifted and eroded over millions of years. No commercial tours operate from the structure itself. Visitors hire 4x4 vehicles in Atar, 100 kilometers south, for day access. The drive requires four hours each direction across sand and rock. No facilities exist at the site. Aerial perspective comes from chartered flights departing Atar or Nouakchott.
Banc d'Arguin National Park covers 12,000 square kilometers of coastal wetlands where the Sahara meets the Atlantic. UNESCO inscribed the site in 1989. The park shelters over three million migratory shorebirds during winter months, including flamingos, pelicans, and terns. Traditional Imraguen fishing communities operate from seasonal camps inside the park using sailboats and cooperating with wild dolphins to drive mullet into nets. Park headquarters sit in Chami. Access requires 4x4 vehicles and advance permits from the National Parks Direction in Nouakchott. No accommodation exists inside park boundaries.

The town contains stone architecture unique among Mauritanian desert settlements, with buildings incorporating decorative facades and narrow passages. Archaeological sites near Tichit yield Neolithic remains dated between 2000-200 BCE. The settlement served as a date trading center during medieval period. Population declined from several thousand to approximately 2,000 current residents. Access requires multi-day 4x4 journeys from Atar or flights to Tichit airstrip when operational.

Nouadhibou contains the world's largest ship graveyard. More than 300 vessels sit rusted in shallow waters along the bay's coastline.
