Although there's little to do in Rosso (pop. 18,000), the drive from Nouakchott is pleasant, passing small villages, interesting people and sand-colored rock buildings. Rosso lies on the Senegal River, in the fertile southern region where the country's crops are grown. It's best seen as a day trip from Nouakchott.
Note: Because of its border location, Rosso has one of the largest black markets in the country. Be sure to steer clear of illegal dealings—the risks far outweigh any gains.
