While most visitors to Mali Ston Bay come to taste the famous Ston oysters, few know that a fascinating secret over four centuries old lies hidden among the floating farms. Abandoned quarantine stations for shellfish – stone witnesses to a time when the Republic of Ragusa, under Venetian influence, protected its citizens from invisible threats from the sea.
What were these stone purification stations actually?
In an era when medicine had yet to discover bacteria or viruses, the people of Dubrovnik intuitively understood that shellfish could transmit diseases. As early as the late 16th century, they established a sophisticated system of quarantine stations – small stone platforms where shellfish were "purified" before being sold at city markets.
Shellfish would be transferred from the farms to these isolated stone structures, where they spent a certain amount of time in fresh seawater before reaching the tables of Dubrovnik's nobility. This procedure, surprisingly similar to modern depuration, was far ahead of its time.
Five preserved stations you can visit
Today, five quarantine stations remain in Mali Ston Bay in various states of preservation. Each has its own story and unique location:
- Hodilje Station – The best-preserved structure, visible from the shore. The stone walls still defy time, and at low tide, you can see the original basins for holding shellfish.
- Bistrina Station – Located opposite the freshwater spring of the same name, which is no coincidence. The mixture of fresh and salt water was considered ideal for purification.
- Mali Ston Station – Integrated into the city walls, it served as the final checkpoint before shellfish entered the town.
- Brijesta Station – The most remote of all, used for shellfish coming from more open waters.
- Luka Station – The smallest, but historically most significant as it is mentioned in Dubrovnik archives from 1581.
How to reach the quarantine stations?
The best way to explore these historical sites is by kayak or small boat. Several local guides offer specialized tours that combine history, oyster tasting, and paddling through the calm waters of the bay.
Organized tours
Organized kayak tours depart from Mali Ston and last about four hours. Prices range from 45 to 60 euros per person, including a guide, equipment, and tasting of fresh oysters directly from the farm. I recommend booking a day or two in advance, especially from June to September.
For those who prefer motorized transport, fishermen from Hodilje offer tours in traditional boats. This option is ideal for families with children or older visitors. Expect a price of 30 to 40 euros for a group of up to four people.
Independent exploration
You can rent a kayak in Mali Ston for approximately 15 euros per hour or 50 euros for the whole day. Look for the agency near the ferry dock – you'll recognize it by the colorful kayaks on the shore. The owner Marko speaks English and German and gladly shares maps with marked historical locations.
Best time to visit
Avoid July and August when the bay is crowded with boats and the temperature makes paddling uncomfortable. The ideal time is from mid-April to late June and throughout September and early October.
Morning hours, between seven and ten, offer calm water and soft light perfect for photographing the old stone structures. Afternoon bura winds can complicate the return, so monitor the weather forecast.
What to bring
- Water shoes – the stone structures are slippery and covered with algae
- Waterproof bag for your phone and documents
- Hat and sunscreen – there's no shade on the bay
- Enough water – at least a liter and a half per person
- Light snack – the combination of physical activity and sea air works up an appetite
Where to eat after the tour
After exploring the quarantine stations, reward yourself with a hearty meal at one of the local taverns. Konoba Bakus in Mali Ston offers oysters for about one and a half euros each – significantly cheaper than in Dubrovnik. Their eel brodet is a recipe several generations old.
Vila Koruna in Ston has a terrace overlooking the salt pans and excellent black risotto. Reservations are recommended, especially on weekends. For a more authentic experience, Kapetanova kuća tavern in Mali Ston serves only what was caught that day – there's no menu, the waiter simply tells you what's available.
Accommodation nearby
Mali Ston Bay offers a more intimate alternative to overcrowded Dubrovnik, just 50 kilometers away. Apartments and vacation homes in Mali Ston, Hodilje, and surrounding villages are a perfect base for exploring this part of the coast.
Accommodation right on the bay allows you to pull out a kayak in the morning, before other guests wake up, and paddle to a quarantine station while the sea is still glass-calm. On BarbaBooking platforms, you can find authentic stone houses with private docks – a luxury that costs a fortune in Dubrovnik is available here at a reasonable price.
Why this isn't a typical tourist attraction
The quarantine stations have no information boards, souvenir shops, or admission tickets. It's precisely this untamed quality that makes them special. You'll stand on the same stone where laborers whose names were long forgotten worked four hundred years ago, looking at the same bay that has barely changed since then.
In an era when every beach is packed with sun loungers and every landmark has a queue for photos, Mali Ston Bay offers something increasingly rare – the possibility of genuine discovery. The quarantine stations ask nothing of you except a little effort to reach them. And in return, they offer a story you'll retell long after memories of Dubrovnik's crowded streets have faded.
Next time you're in southern Dalmatia, set aside one day for this unusual adventure. Your oysters will taste quite different when you know what kind of quality control system they went through centuries before you.
