Nevis (/ˈniːvɪs/ NEE-viss) is an island in the Caribbean Sea that forms part of the inner arc of the Leeward Islands chain of the West Indies. Nevis and the neighbouring island of Saint Kitts constitute the Federation of Saint Kitts and Nevis, a sovereign state. Nevis is located near the northern end of the Lesser Antilles archipelago about 350 kilometres (220 mi) east-southeast of Puerto Rico and 80 kilometres (50 mi) west of Antigua. Its area is 93 square kilometres (36 sq mi) and the capital is Charlestown.
Saint Kitts and Nevis are separated by The Narrows, a shallow 3-kilometre (2 mi) channel. Nevis is roughly conical in shape with a volcano, Nevis Peak, at its centre. The island is fringed on its western and northern coastlines by sandy beaches composed of a mixture of white coral sand with brown and black sand eroded and washed down from the volcanic rocks that make up the island. The gently-sloping coastal plain (1 km (0.62 mi) wide) has natural freshwater springs as well as non-potable volcanic hot springs, especially along the western coast.
