Has anyone visited Lopud, 30kms northwest of Dubrovnik? If so, what's it like? I'm looking for somewhere off the beaten track, quiet, hot with a bit of restaurant action at night and plenty of calm sea swimming in the day, plus day trips. Really want to go to those lakes so might try for a day trip from here. Don't think I want to hoof around too much. Am there for about 10 days mid August.
