Dubrovnik and the Bay of Kotor are 90 km apart. Split the trip rather than day-tripping back and forth — two nights in Dubrovnik, three or four in Montenegro.
Old Town walls, Lokrum or the Elaphiti islands by boat, Cavtat or Konavle in the hinterland.
Two to two and a half hours via the Debeli Brijeg crossing, with stops at Herceg Novi and Perast. A private transfer costs €90–€140 per car and the driver handles the queue.
Old Town, boat tour to Our Lady of the Rocks and the Blue Cave, Lovćen and Cetinje.
Either north for Tara rafting and Durmitor, or south for Budva, Sveti Stefan and Lake Skadar.
Yes. Kotor is 90 km away, about 2–2.5 hours including the Debeli Brijeg border. Day trips and private transfers run daily.
No for EU, UK, US, Canadian and Australian passports — a passport is enough for both countries. Check rental-car cross-border permission before driving.
Usually 15–40 minutes, but it can reach two hours mid-morning in July and August. Crossing before 8 am or after 6 pm is fastest.
