Cayenne is a small capital and its sights can be walked in a single day. The compact old centre between the Place des Palmistes and the waterfront has the colonial-era buildings, the cathedral and the market; the wooded heights of Fort Cépérou give an overview of the city and its harbour. The Jardin Botanique and the Musée Départemental fill an interesting half-day. For more, head out to the Îles du Salut or the Centre Spatial Guyanais at Kourou.
