Saint Kitts and Nevis, officially the Federation of Saint Christopher and Nevis (or the Federation of Saint Kitts and Nevis), located in the Leeward Islands, is a unitary island nation in the Caribbean and the smallest nation in the Americas in both area and population. The capital city and government for the federated state is mainly on the larger island of Saint Kitts (formerly named Saint Christopher). The smaller state of Nevis (formerly named: Nuestra Señora de las Nieves) lies about 3 km southeast of Saint Kitts. Historically the British dependency of Anguilla was also a part of this union, which was then known collectively as Saint Christopher-Nevis-Anguilla.
Although Saint Kitts and Nevis are geographically within the Leeward Islands, they are relatively close to a cluster of several other islands. To the north-northwest lie the islands of Saint Eustatius, Saba, Saint Barthélemy, and Saint Martin. To the northeast are Antigua and Barbuda, and to the south-east is Montserrat.
Both the names Saint Christopher and Saint Kitts are given in the Constitution of Saint Christopher and Nevis
Saint Kitts and Nevis are a pair of tropical islands in the Caribbean, about one-third of the way from Puerto Rico to Trinidad and Tobago.
Tropical tempered by constant sea breezes; little seasonal temperature variation; rainy season (May to November)
With coastlines in the shape of a baseball bat and ball, the two volcanic islands are separated by a three-km-wide channel called The Narrows; on the southern tip of long, baseball bat-shaped Saint Kitts lies the Great Salt Pond; Nevis Peak sits in the center of its almost circular namesake island and its ball shape complements that of its sister island. The highest point is Mount Liamuiga (St Kitts) at 1,156 meters.
