We're looking at a holiday plan that arrives in Rijeka in the evening by train, and then want to spend a few days by the beach. Up to a 40km taxi ride would be about 25 euros right? The ideal would be a small town or village, and a nice beach that doesn't get really crowded in summer (not expecting it to be dead quiet, just not packed). On a bus route would be nice, but not essential. Any suggestions on what would fit best?
