The territory of Bulgaria has about 500 deposits of mineral waters with over 1,600 water sources. They are localized chiefly at the mountain foothills. The spa resorts of national significance are Bankya, Velingrad, Sandanski, the mineral baths of Stara Zagora, Narechen, Sliven and Haskovo, as well as Kyustendil, Varshets, Pavel Banya, Hisar, Merichleri, Momin Prohod and Kostenets.
     Climatic seaside resorts offering various recreation services are Balchik, Burgas, Varna (Golden Sands), Kiten, Pomorie, Primorsko, Nessebar (Sunny Beach), and Sozopol.
     Picturesque lakes hide in the cirques of Rila and Pirin Mountains. Dam lakes of recreational potential are to be found in the Rhodope Mountain – namely Batak, Vatcha, Studen Kladenets, at the foot of the Balkan Range – Ticha, as well as in some other places.
     There are good prerequisites for the development of adventure tourism: "wild waters" – rafting and canoe, diving, delta- and par drifting in the river valleys of Vatcha, Iskar, Chepelarska, Struma, and Mesta rivers.
