Kobaš sits at the point where the south coast of Pelješac runs up against a ridge of hills steep enough that the road from Ston, just seven kilometres away, was not completed until roughly ten years ago. Before that, the only way in or out was by sea — which is why the village earned its enduring description as 'the island on the peninsula'. The place is first documented in 1422, when the Dubrovnik Republic designated the bay as a lazaretto: a quarantine stop where ships arriving from plague-affected ports were held before they were permitted to continue to Ston. In the eighteenth century the Betondić family, Dubrovnik nobility, built a summer residence and chapel on the hillside above the shore; the poet Jozo Betondić wrote here and translated Ovid. The remains of the residence still stand beside today's taverna. By the twentieth century Kobaš had contracted to a fishing village of seven families. In October 1943 German forces burned the settlement and killed the inhabitants. A monument above the shore marks the site.
What draws boats to Kobaš today is straightforward: the food. Luka's Taverna has been open as a family business since 1985. The kitchen is built around whatever the fishing boats landed that morning — grilled over an open fire, served with oysters from Mali Ston Bay (the next inlet along, whose shellfish carry a recognised designation of origin), and accompanied by Plavac mali, the indigenous Pelješac red that is the genetic parent of Californian Zinfandel and the wine that most of the peninsula's families grow. Twenty steps from Luka's, Gastro Mare runs a different kind of kitchen: a chef with years in Scandinavia and the United States works with the same raw materials — the restaurant's own garden, its own fishing boat, its own olive oil — but applies different technique. Both restaurants offer mooring directly in front of the jetty.
The bay itself does what a good anchorage should: it holds the wind out. The surrounding hills mean that even on days when conditions in the open channel are uncomfortable, Kobaš is calm — the kind of calm that makes it easy to stay longer than you planned. The beach is sand, which is rarer on this part of the coast than the Dubrovnik beaches suggest, and the water is clear and shallow enough at the edges for an easy swim before lunch. For guests on our Ston and Kobaš tour, this is the main stop of the day — not a swim break between two other things, but the reason the itinerary exists.
