Francophone Senegal is one of the most popular tourist destinations in West Africa. The capital of Dakar is the end point of the Paris-Dakar motor rally, and also contains the IFAN museum – a large collection of West African art and history that is considered to be one of the best in the region. Nearby Dakar is the Ile De Goree, a world heritage site that is famous for being a slave-trading base. The House of Slaves remains as a reminder of the dark past. For more cheerful excursions, there is the popular beach resort of Cap Skiring and the fascinating Lac Rose, which is a pink lake that changes colour to violet with the setting sun. Nature lovers can check out the Parc National de Niokolo-Koba, which is Senegal’s best national park and contains hippos, buffalo, antelope, and crocodiles, as well as rarer sightings of elephants, lions and chimpanzees. Finally, the Basse Casamance region in the south is notable for its tropical setting and different culture. However, separatist unrest has made the area unstable in the past.
