Ulcinj is the southernmost town on the Montenegro coast, and it plays by slightly different rules than Kotor or Budva. The town itself is built on a hillside above a long crescent beach, but the real reason travelers rent a car here sits a few kilometers further south: Velika Plaza, the Great Beach, stretches for roughly 12 kilometers of open sand, and public transport along it is thin on the ground. With your own car, the whole southern coast opens up in a way that simply does not work on buses and taxis alone. Most visitors pick up their car at Podgorica airport, about an hour and a half north, and drive straight down the E65. A smaller number cross the border from Albania at Sukobin, which is only fifteen minutes from town. Either way, it makes sense to arrange Ulcinj car rental before you land rather than after: in July and August the small local fleets are routinely booked out, and the remaining cars go at peak-season prices. Booking ahead from home also lets you check the paperwork calmly - you will need a passport, a driving license, and a credit or debit card in the driver's name, and if you plan to cross into Albania or Bosnia later, ask the rental company for the extra vehicle documents in advance, because not every insurer issues them on the spot. Driving around town takes a day or so to get used to. The old town streets are narrow and steep, parking in the center is tight in the evenings, and local drivers are assertive on the coastal bends. Once you escape the town, the roads reward you. South to Ada Bojana, the island where the Bojana river meets the Adriatic, is an easy twenty-minute drive past fish restaurants and kite-surf spots. North, the road to Bar and onward to Sveti Stefan makes one of the nicer coastal drives in the Balkans. Inland, the Skadar Lake region - Virpazar, boat trips, vineyards around Plantaže - fits neatly into a half-day loop. None of these trips work well by bus; all of them work by car. Two seasonal notes worth remembering. First, the coastal road between Ulcinj and Bar narrows and slows through several villages, so add margin to any drive-to-the-airport plan on summer Saturdays. Second, sunbed rows on Velika Plaza start after the dunes - if you prefer the wilder southern end near the river mouth, park at the designated lots and walk the last few hundred meters; informal parking on the sand itself is a quick way to meet a tow truck. Fuel, insurance, and small scratches are where rental disputes are born everywhere on the coast, and Ulcinj is no exception. Photograph the car at pickup, including the wheels and windshield, keep the contract until you are home, and return the car with the same fuel level you started with. Do that, and a rental car stops being a worry and becomes what it should be on this stretch of coast: the tool that turns a beach holiday into a proper exploration of Montenegro's south.
