Why September

The second week of September is arguably the finest window on the Adriatic. The sea holds its summer warmth while the summer crowds dissolve — mooring becomes effortless, restaurant tables appear without a reservation, and the mountain light turns amber and theatrical each evening. Three days is enough time to taste the Bay of Kotor, cross into Croatian waters, and return with a sunburn and a full notebook.

07:30
Morning Coffee at Porto Montenegro Marina
Begin at the promenade of Porto Montenegro — Europe's premier superyacht marina. Walk the waterfront, grab espresso at one of the marina café terraces, and complete pre-departure checks. The morning light on the bay is exceptional before 9am.
Base Port
09:00
Cast Off — Sail to Kotor (8 nm)
Head east across Tivat Bay and into the inner Boka Kotorska. The channel narrows dramatically as cliffs rise above 1,000m on both sides — Montenegro's famous "fjord." Maestral winds typically pick up by mid-morning. Drop anchor at Kotor's outer anchorage or take a bow berth at Kotor marina.
Sailing · ~1.5 hrsUNESCO Bay
10:30
Kotor Old Town — Walled City Walk
Kotor's perfectly preserved medieval walls date to the 9th century. Walk through the Sea Gate, visit St. Tryphon's Cathedral (1166 AD), and climb the 1,350 steps to the Fortress of St. John for panoramic views over the entire bay. Allow 2–3 hours. September means the cruise ship crowds are thinning — arrive at the fortress before noon for the best photos.
UNESCO World HeritageMedieval Walls
13:30
Lunch in Kotor's Old Town
Try Restoran Scala Santa for grilled sea bream and local prosciutto from the Njeguši highlands, or Galion on the waterfront for Montenegrin black risotto made with Adriatic cuttlefish. Pair with a local Vranac red or crisp Krstač white wine.
Konoba DiningLocal Wine
15:00
Sail to Perast — Our Lady of the Rocks (5 nm)
The short sail northwest brings you to Perast, an exquisite baroque village with 16 churches and a dozen noble palazzos. Anchor and take the water taxi (€5) to Gospa od Škrpjela — Our Lady of the Rocks — a tiny artificial island built atop a 15th-century shipwreck bearing an icon said to have miraculous powers. The church interior contains 68 paintings by Tripo Kokolja and thousands of silver votive tablets.
Sailing · 45 minSacred Island
17:30
Sunset Swim Anchorage
Drop anchor in the calm bay just south of Perast. The water here is gin-clear and protected. September sea temperature sits around 24–26°C — ideal for a long afternoon swim. Watch the sun drop behind the Orjen mountains: the light show is extraordinary on the limestone cliff faces.
SwimmingSnorkeling
20:00
Dinner at Perast Waterfront
Return to Perast for dinner at Conte or Restoran 4 Kantuna — both set in converted baroque palaces with terrace tables inches from the water. Order the grilled octopus salad and lamb slow-cooked under the peka. Overnight at anchor or Perast town dock.

Border Crossing
to Dubrovnik
Perast → Herceg Novi → Cavtat → Dubrovnik Old Town
07:00
Early Departure — Sail to Herceg Novi (18 nm)
Leave Perast at first light to arrive in Herceg Novi before the heat of the day. The sail out through the Bay of Kotor channels past the dramatic Verige Strait — Montenegro's narrowest point — and opens onto the Adriatic. Winds typically freshen to 12–18 knots as you leave the bay. Herceg Novi sits at the mouth of the bay, surrounded by fortress walls and dense Mediterranean vegetation.
Sailing · ~2.5 hrs
09:30
Herceg Novi — Fortresses & Seafront Promenade
Tie up at the city quay or the ACI Marina. Walk the Šetalište, Herceg Novi's legendary flower-lined seafront promenade. Visit the Kanli Kula ("Bloody Tower") Ottoman fortress for views of the open Adriatic and Croatian coast on the horizon. Don't miss the 14th-century Fortemare sea fortress — its gate opens directly onto the water at low tide.
Ottoman FortressPromenade
11:00
Border Crossing — Montenegro to Croatia
Check out of Montenegro at the Herceg Novi harbour office (bring all passports, vessel papers, and vignette). The crossing to Cavtat, Croatia is approximately 32 nautical miles across open Adriatic water. The cliffs of the Dinaric Alps dominate the coastline — Bora gusts can be unpredictable near the headlands, so offshore sailing is advisable. Allow 3.5–4 hours passage time. Check into Croatia at Cavtat harbour authority.
Open Adriatic · ~32 nm · 3.5 hrsBorder Formalities
14:30
Cavtat — Hidden Gem Before Dubrovnik
Cavtat is everything Dubrovnik was before it was discovered: a walled Ragusan town on a double bay, almost entirely free of cruise ship crowds. Walk to the Račić Mausoleum (Ivan Meštrović, 1921), visit the Gallery of Vlaho Bukovac, and swim off the town's small rocky beaches. The water here is spectacularly clear. Lunch at Konoba Kolona — order the Peka lamb or fresh catch of the day.
Ragusan TownCrystal WaterLocal Konoba
16:30
Sail to Dubrovnik (8 nm)
The short sail from Cavtat to Dubrovnik Gruž harbour is one of the great approaches in sailing — the city walls emerge from the cliff face, burning white-gold in afternoon light. Berth at ACI Marina Dubrovnik or anchor in the bay south of Lokrum island. The island of Lokrum is a nature reserve with a botanical garden, Benedictine monastery, and nude beach — all accessible by water taxi.
Sailing · 45 min
18:00
Walk Dubrovnik's City Walls at Dusk
The 2km wall circuit is Dubrovnik's signature experience — and September twilight renders it in its most cinematic version, without the 10,000-person peak-summer crush. Enter at the Pile Gate. The views over the terracotta rooftops, the Adriatic, and the island of Lokrum are arresting at any time but almost surreal at golden hour. Time your walk to finish as the city lights come on.
UNESCO Walls2km Rampart
20:30
Dinner in Dubrovnik's Old Town
Restaurant 360° (Michelin-recommended) sits in a bastion of the city wall with views of the sea through the embrasures — reserve in advance. For a more local experience, Konoba Dubrava outside the walls offers excellent slow-cooked lamb, Pelješac oysters, and Dingač red wine from the Pelješac peninsula. Walk Stradun (the marble main street, polished glassy smooth by centuries of foot traffic) after dinner — it glows at night.

Morning Explore — Lokrum Island
Take the water taxi from Dubrovnik's old harbour to Lokrum (10 min, €5 return). The Benedictine monastery gardens contain peacocks, subtropical plants, and a saltwater lake (Mrtvo More — "the Dead Sea") connected to the sea by underwater channels. Swim in the lake or off the island's flat rocks. No cars, no crowds before 9am.

10:00
Sail to Lopud Island — Elaphiti Islands (12 nm)
Head northwest from Dubrovnik into the Elaphiti archipelago. Lopud is the most beautiful of the three inhabited islands — car-free, with a single village, a 15th-century Franciscan monastery, and Šunj Beach, widely considered one of the finest sandy beaches on the entire Croatian coast (rare on this rocky coast). Moor at the town quay.
Sailing · ~1.5 hrsŠunj Beach · Sandy
11:30
Lopud — Walk, Swim, Franciscan Monastery
Walk 20 minutes through olive groves and pine forest to Šunj Beach. September means the beach is uncrowded and the sea is at its warmest. Swim, snorkel, or simply lie still. The shallow, sandy bay is protected from swell. Return to the village and visit the Franciscan Monastery of Our Lady of Špilja (15th century) — the cloister garden overlooking the sea is exceptional.
Šunj Sandy BeachFranciscan Cloister
13:30
Lunch on Lopud
Obala Restaurant on the Lopud waterfront is the island's best table — fresh-caught bream, squid ink pasta, and grilled scampi with local wine. Sit outside facing the sea and the distant Montenegro mountains.
Island Lunch
15:00
Open Adriatic Passage — Return to Montenegro (38 nm)
The return crossing south and east crosses the open Adriatic. September afternoons bring reliable Maestral from the northwest — this is typically a beam reach, one of the most exhilarating points of sail. The Montenegro mountains appear on the horizon about an hour out and grow progressively more dramatic. Check back into Montenegro at Zelenika or Herceg Novi (call ahead — hours vary) before entering the Bay of Kotor.

Arrive Porto Montenegro — Sundowner at the Marina
Sail back into Tivat Bay as the day cools. Take a bow berth in Porto Montenegro, clean up, and walk to the promenade for the classic marina sundowner — a glass of rosé or a local craft beer watching the superyachts light up. The Naval Heritage Collection Museum (Soviet-era submarines and vintage vessels) is worth a quick walk-through if it's still open.
Return to BaseNaval Museum
20:30
Farewell Dinner — Porto Montenegro Promenade
Maestral Restaurant at Porto Montenegro or One Restaurant at the Regent Porto Montenegro hotel offer polished Montenegrin cuisine with marina views. For something more atmospheric, take a 10-minute taxi to Kotor for a final evening in the walled city — dinner at Bokun in an old stone house on a lamp-lit medieval square.
