You do not need a car in Montenegro if you stay on the coast and use day tours for the interior. The bus network along the coast is cheap and frequent; the mountains are where tours replace driving.
Everything inside the walls plus the fortress climb — no transport needed.
Boat tours leave from the Kotor waterfront, five minutes from any hotel in town.
The Kotor–Herceg Novi bus stops above Perast every hour; the island boat leaves from the waterfront.
There is no practical bus up the serpentine — a day tour is the only sensible option, and it includes the Njeguši stop.
Buses to Budva run every 30 minutes and take 40 minutes. For Skadar Lake, take a tour from Kotor or the train from Bar to Virpazar.
Not if you stay on the coast. Buses connect Herceg Novi, Kotor, Budva, Bar and Ulcinj frequently and cheaply, and day tours cover the interior.
Kotor to Budva is around €4, Kotor to Podgorica about €7. Tickets are bought at the station or on the bus, cash preferred.
