The Adriatic Sea from Split to Dubrovnik is gorgeous, very clean, and includes 22km of Bosnia and Herzegovina. The closed bay at Neum is protected from the strong open sea winds by the Peljesac Peninsula, and wonderfully calm.

Neum is the only exit of Bosnia and Herzegovina to the coast. It was first mentioned in 533 (under the name Neunense), but was developed as a maritime retreat in 1965. The Old Town of Neum is 2 km inland.
Scuba-diving, parasailing, boating and jet skiing can all readily be arranged in any of the major hotels. It all costs a little less than what it costs in Croatia. During the season, it is wise to book in advance. There are over 7000 beds in hotels, B&Bs, guest houses and private accommodation.
