Three quarters of gross value added are created by services. In 2008 almost a fifth of gross value added was created by transport, activities in the Port of Koper representing the highest share. The shares of hotels and restaurants and of coastal and spa tourism in the total gross value added are higher than in other regions.

The Obalno-kraška region recorded a quarter of all tourist overnights in the country in 2009; almost a half by domestic tourists. As regards foreign tourists, Italians, Austrians and Germans predominate.
