We visited Cavtat on a day out from Dubrovnik. The owner of our accommodation suggested it to us. We travelled by local bus which we caught by the Dubrovnik cable car. Cavtat is a pretty place with a lovely harbour and sea front restaurants. We spent a nice relaxing day there, away from the hustle and bustle of Dubrovnik. Well worth a visit if you are staying in Dubrovnik for a few days.
