Experience Montenegro with us. Medieval features will be following us almost on the entire trip. Kotor Old town is breathtaking. Bay of Kotor – Boka kotorska – is one of the largest bays at the Adriatic, it is quite indented. Even though many refer to it as to a fjord, it is actually a ria which is a sunken river canyon. No wonder that Kotor is a UNESCO World Heritage Site since the landscape is so impressive and unique, together with limestone Orjen and Lovćen cliffs.
