The bays of Brna and Istruga are situated in the middle of the south side of the island of Korcula, protected by all sides from the neighbouring mounts, especially from the north side, and they are open towards the west side to the sea, which gives special climatic characteristics to this part of the island. The bay of Brna has been well-known tourist resort for more than thirty years. The hotel "Feral" and numerous smaller tourist objects with various facilities have been built here. Rich layers of the medical mud liman can be found in the bay of Istruga which is 500 metres long, 150 metres wide with the layers of mud 6 metres thick extending to the half of the bay. It is not very well known that, beside in Vela Luka, on the island of Korcula there are also rich layers of peloid, medical mud, in the vicinity of the bay of Brna, more exactly 500 meters to the north in the bay of Istruga. This is a mud of a high hygienic standard and very good quality, as there are practically no buildings here except a smaller sport and recreation centre with two tennis grounds, a restaurant with a dancing terrace and two family houses. The whole this region is exceptionally rich in pine coniferous wood and other Mediterranean plants, as is almost the whole island, and especially its south part. Small road leads from Smokvica towards bay of Brna, a built-up bay with a quay from many yachts and small boats The "Feral" hotel lies at the very cape of the bay. The biggest wine-cellar on the island, lies on the road to Brna; the famous "Posip" and "Marastina" wines are prepared here by a modern wine-making process. This cellar also produced the "Lozovaca" and "Travarica" brandies.
