Porat Bay Biševo on the island of Biševo is one of the Adriatic’s most enchanting natural harbours — a sheltered crescent of pebble and sand fringed by wild Mediterranean vegetation and backed by the gentle slopes of Croatia’s most mysterious small island. Just a short sail from the legendary Blue Cave, Porat Bay Biševo offers everything a sailor could wish for: calm turquoise water ideal for swimming and snorkelling, dependable shelter from open-sea swells, and the rare luxury of genuine remoteness. With fewer than fifteen permanent residents on the entire island, anchoring here feels like stepping into an Adriatic that most travellers only dream about — a perfect stop on a crewed yacht charter exploring Croatia’s hidden islands.
How to Reach Porat Bay by Boat
Biševo island lies approximately five nautical miles southwest of Komiža on Vis island. Porat Bay Biševo sits on the island’s northern shore, making it the natural first stop after visiting the Blue Cave on Biševo’s eastern tip. From the Blue Cave entrance, simply follow the coast westward for about one nautical mile and the wide, welcoming mouth of Porat opens before you.
If you are sailing directly from Komiža, set a course south-southwest and you will spot the bay after roughly forty-five minutes of easy cruising in typical summer conditions. The approach is clear of hazards; the bay entrance is wide and deep, with no hidden rocks or shoals to worry about. Depths decrease gradually from fifteen metres at the mouth to three or four metres near the beach, giving you plenty of room to choose your anchoring spot. For sailors exploring the wider Vis archipelago, Porat is the most accessible and versatile anchorage on the island.
Swimming & Snorkelling
The water inside Porat Bay is extraordinarily clear. The mixed pebble-and-sand bottom creates a luminous turquoise palette that shifts to deep blue toward the centre of the bay. Summer temperatures range from twenty-three to twenty-six degrees, and the sheltered aspect means the surface is often mirror-calm in the morning hours — perfect conditions for a sunrise swim off the stern of your yacht.
Snorkelling at Porat Bay Biševo is among the finest you will find in the Croatian islands. The rocky edges of the bay are home to dense colonies of sea fans, sponges, and a vibrant population of ornate wrasse, painted comber, and damselfish. Visibility frequently exceeds twenty metres. Keen snorkellers should explore the boulders on the western side of the bay, where crevices shelter spiny lobsters and octopus. If you carry a freediving mask, the underwater cliff that drops away just outside the bay mouth is a thrilling wall dive in miniature.
What to See & Do
Porat is the historical heart of Biševo. A short walk from the beach leads to the tiny church of Saint Silvester, thought to date from the eleventh century, and the scattered stone ruins of a small Benedictine monastery. The island’s handful of residents tend vineyards and olive groves on the terraced hillside above the bay — a pastoral scene that has barely changed in centuries.
The Blue Cave, Biševo’s star attraction, is just a nautical mile to the east and is an essential day-trip highlight for anyone anchoring at Porat Bay Biševo. On the island’s southern coast, the lesser-known Monk Seal Cave (Medvidina špilja) can be explored by dinghy on calm days. Back at Porat, kayaking along the rocky shoreline or simply paddleboarding across the glassy bay are idyllic ways to spend an afternoon. When the light fades, the absence of light pollution makes Porat one of the finest stargazing spots in the entire Croatian archipelago. Many guests exploring the region with Splendid Yachting rate an evening at Porat Bay among their most memorable nights afloat.
Anchoring & Mooring
Porat Bay is the most protected anchorage on Biševo and one of the best shelter spots in the wider Vis archipelago. Anchor in five to ten metres of water over a sandy bottom with good holding. The bay is open to the north but is well protected from the prevailing summer maestral (north-west) and from southerly winds. In settled summer weather, overnight anchoring is comfortable and safe.
Space is limited — the bay can comfortably hold six to eight boats depending on size and swing room. During peak season, arrive before midday to secure a good spot. There are no permanent mooring buoys or shore lines; occasional summer buoys may be deployed by local operators but should not be relied upon. Ensure you have adequate scope on your anchor chain. If a strong north-easterly bura is forecast, relocate to the south side of Biševo or return to Komiža, as the bay becomes exposed in those conditions.

Best Time to Visit
June through September is the prime window for visiting Porat Bay Biševo. June offers the loveliest combination of warm weather, calm seas, and low visitor numbers — perfect for sailors who prize solitude. July and August see more boats, particularly those making a day trip from Vis after the Blue Cave, but mornings and evenings remain peaceful. September is glorious: the water retains its summer warmth, the autumn light is soft and golden, and the anchorage is yours to enjoy in near-privacy. Early-season visitors in May may find the water refreshing at around twenty degrees but will be rewarded with wildflowers covering the hillside. Nearby anchorages like Stiniva Beach and Smokva Bay on Vis offer excellent alternatives when planning your island-hopping itinerary.
Essential Tips for Visitors
Biševo has virtually no commercial services. There is a single small konoba near Porat Bay that opens sporadically in summer — do not count on it for provisions. Carry all the food, water, and fuel you need from Komiža or Vis town. Rubbish facilities are non-existent, so pack out everything you bring.
Sun protection is critical; the bay’s south-westerly aspect means full afternoon sun with little natural shade on the beach itself. A bimini or cockpit awning on your yacht is your best friend. Bring a good snorkel set and water shoes for the rocky shoreline. If you plan to visit the Blue Cave, check the daily entry schedule with local operators in Komiža before you depart — the cave can be closed when swell conditions make entry unsafe.
Experienced crews with Splendid Yachting’s luxury crewed charters appreciate the bay’s protected nature and strategic location within island-hopping routes that include Hvar, Korčula, and the remote beauty of Lastovo. Above all, respect this fragile island environment: Biševo’s beauty lies in its untouched simplicity, and every visitor shares the duty to keep it that way.

Frequently Asked Questions
Can I stay overnight at Porat Bay Biševo?
Yes, overnight anchoring at Porat Bay is both safe and comfortable in settled summer weather. The bay offers excellent protection from the prevailing maestral and southerly winds. However, monitor weather forecasts carefully — if a north-easterly bura is predicted, relocate to a more sheltered anchorage as Porat becomes exposed to northerly conditions. The bay’s sandy bottom provides good holding, but ensure adequate anchor scope. With no light pollution and minimal boat traffic after sunset, spending the night here is a genuinely magical experience.
Are there any facilities or restaurants at Porat Bay?
Porat Bay has virtually no tourist infrastructure. A small traditional konoba occasionally opens during peak summer months, but it operates sporadically and should not be relied upon for meals or provisions. There is no fuel, no water supply, and no rubbish disposal. The nearest reliable services are in Komiža on Vis island, approximately five nautical miles away. Plan accordingly: stock up on food, water, and fuel before departing, and carry all waste with you when you leave. This lack of development is precisely what makes Porat so special — it remains one of the Adriatic’s most unspoiled anchorages.
How far is Porat Bay from the Blue Cave?
Porat Bay lies approximately one nautical mile west of the Blue Cave entrance, making it the ideal anchorage before or after your cave visit. The short sail takes about ten minutes in calm conditions, and the coastal route is straightforward with no navigational hazards. Most yachts visit the Blue Cave in the morning when light conditions inside are optimal, then sail the short distance to Porat Bay for swimming, lunch, and relaxation. This combination — the ethereal beauty of the Blue Cave followed by the serene turquoise waters of Porat — creates one of the most memorable days you can experience in the Croatian Adriatic.
What other anchorages are near Porat Bay?
The wider Vis archipelago offers several excellent alternative anchorages within easy sailing distance of Porat Bay. Stiniva Beach on Vis’s southern coast is a dramatic fjord-like cove with stunning scenery, though space is limited. Smokva Bay on Vis’s north coast provides excellent all-round shelter and is a popular overnight stop. For those seeking true seclusion, the anchorages around Šćedro island between Vis and Hvar offer pristine waters and reliable shelter. Each of these destinations complements Porat beautifully in a week-long itinerary exploring Croatia’s most enchanting islands.
