Duni can be found in a peaceful bay on Bulgaria's Black Sea coast. The golden sands are a real draw for people who'll be spoilt for choice of things to do. Dive down to the shipwrecks that Sozopolare below the oceans or tuck into a great seafood lunch down at the Old Town in Sozopol. How about visiting a castle that's fit for a fairy tale? The majestic Ravadinovo Castle is only a short drive away.
