With it's unique bombed-out look, Kotor's bus station is a 10-minute walk south of the old town and has smashing views of the rockface directly behind. If you want to use a bus, you'll have to brush up on your Cyrillic, as it is beyond the city's budget to post the destination names in Latin script. There's a ticket office but they don't speak foreign and you have to buy most tickets from the driver anyway, so simply rock up 15 minutes before departure.
