The Coastal–Karst Statistical Region (Slovene: Obalno-kraška statistična regija, Italian: Litorale-Carso) is a statistical region in southwest Slovenia. It covers the traditional and historical regions of Slovenian Istria and most of the Karst Plateau, which traditionally belonged to the County of Gorizia and Gradisca. The region has a sub-Mediterranean climate and is Slovenia's only statistical region bordering the sea. Its natural features enable the development of tourism, transport, and special agricultural crops. More than two-thirds of gross value added are generated by services (trade, accommodation, and transport); most was generated by activities at the Port of Koper and through seaside and spa tourism. The region recorded almost a quarter of all tourist nights in the country in 2
