There are frequent buses, operated by "Blueline", connecting the town of Herceg Novi with the ferry port at Kamenari.
The ferry port at Kamenari is significant because the ferry that makes the short crossing from there to Lepetane cuts out the need to drive 30km+ around the Bay of Kotor, and so significantly reduces the travel time between Herceg Novi and the towns of Kotor and Tivat.
During our visit to Montenegro in May 2012, we made use of the Kamenari-Herceg Novi bus on our way back from Tivat. It was the final leg of a journey that consisted of a bus from Tivat to Lepetane, the ferry from Lepetane to Kamenari and then a bus ride from Kamenari to Herceg Novi.
The following information was correct as at that time:
Kamenari to Herceg Novi bus
When we alighted the ferry at Kamenari, there was a Blueline bus to Herceg Novi parked up across the road. However, it was not timed to coincide with the arrival of the ferry since it began to depart and only stopped after several passengers ran across the road to flag it down.
We boarded the bus via the rear doors where we found a conductor sitting at a counter selling tickets. The tickets cost 1.30 Euros each.
The bus got busier and busier as we approached Herceg Novi, with passengers boarding at several stops including Bijela, Kumbor and Zelenika. It was standing room only by the time we arrived at Herceg Novi bus station after a journey of around 20-25 minutes.
During our stay in Herceg Novi, we noticed that the buses to Kamenari operated frequently (perhaps every 15 minutes), even late at night.
Herceg Novi bus station is located on the main road above Stari Grad.
The Lepetane – Kamenari ferry provides a very useful short-cut across the Bay of Kotor.
The short ferry crossing (around 5 minutes) removes the need to drive around some 30km+ of road along the northern coast of the Bay of Kotor, thereby significantly reducing the travel time between Herceg Novi and the towns of Kotor, Tivat and Budva for example.
We made use of the Lepetane-Kamenari ferry during our visit to Montenegro in May 2012. We were travelling back from Tivat to Herceg Novi and decided to go via the ferry route rather than the longer bus route. This involved taking a bus from Tivat to Lepetane, the ferry across to Kamenari and then a bus from Kamenari to Herceg Novi.
The ferry runs every few minutes, in both directions, from 5am until midnight between October and May, and 24 hours a day during the busier summer months.
Best of all, the ferry is free for pedestrians and cyclists and there is a small charge for motor vehicles. There were a few trucks and a handful of cars on board when we crossed, but apparently some of the inter-town buses travel on the ferry as well.
As well as being a convenient mode of transport, the ferry also provides excellent views; in particular up the bay to the beautiful town of Perast and its offshore islands.
The port at Lepetane is less than a 10 minute drive from Tivat, while the port at Kamenari is around 20 minutes driving time from Herceg Novi. There were frequent buses between Herceg Novi and Kamenari (operated by "Blueline") at the time of our visit, but we found ourselves waiting a little longer (just over 30 minutes) for a bus from Tivat to Lepetane.
We caught the local bus from just outside the old town of Herceg Novi on Save Kovacevica street. The line runs from Igalo to Kamenari. You have to get on through the back door where you pay the conductor who has his seat there. We paid Euro 1.30 one way. The bus runs about every 30 minutes in the tourist season.
In Kamenari the end stop is just a bit further than the ferry crossing to Lepetane. At the end stop there is also a post office with a friendly lady. I bought some stamps there. (see picture no. 2)
In the other direction from the ferry crossing there is another bus stop by a brand new tourist office. You may want to grab the Herceg Novi map there which shows also the Kamenari to Igalo stretch of coast. We got this map free of charge at our hotel in Herceg Novi.
These ferries cross the Kotor Bay about every 15 minutes in peak season. If you need to go to Tivat from Herceg Novi then this is the quickest way. Or also to Kotor if you wish to avoid driving along the whole Bay of Kotor, then you should take this ferry which is free of charge for pedestrians. Fees for cars etc. are quite low too. There is a toilet on the ferry should you need it.
When you cross the bay, make sure that you look towards the bay so that you can see the town of Perast in the background between the two narrowest points of land.
If you are traveling from Tivat to Herceg-Novi or Dubrovnik, the Trajekt allows you to cut off a large amount of time you would have to otherwise spend driving around the Bay of Kotor.
The cost to take a car on the ferry across the bay was 3,50 Eurodollars. It ran constantly - every 15 minutes. I could have sworn the ferry crossed the neck of the Bay at least 91 times each day!
