The international airports are Tivat (about 20 minutes by car from Kotor) and Podgorica (about 1.5–2 hours from Kotor). Intercity travel is mainly by long-distance bus, with fairly dense routes such as Kotor–Budva–Herceg Novi–Podgorica; tickets are mostly bought at station windows or in cash on board, and at small stops you need to hail the bus at the roadside; frequencies and fares are subject to official and station announcements. Rail covers only some inland routes and is not suitable as the main transport between bay cities. Kotor Old Town is a pedestrian zone, with vehicles parked in paid car parks outside the town; in summer, boats run in the bay between islands and coastal towns, with more sailings in peak season. Mountain roads are narrow and winding: Kotor to Žabljak is about 150 km and still normally takes 2.5–3 hours, longer in rain or fog; uphill vehicles have priority on narrow roads (subject to local traffic rules). For taxis, use licensed platforms or vehicles queuing at stations; around Tivat Airport there have been cases of gross overcharging, so confirm the price or meter before setting off. Fines for travelling without a ticket, illegal parking and the like are on the order of tens to hundreds of euros, subject to official announcements. Please also note: Montenegro is not an EU country, EU roaming does not apply, so arrange a local SIM or eSIM in advance.
