Roman history, rocks to jump from and an island group full of nature.
Start early at the Arena, before the coaches arrive, then walk through the Golden Gate to the Temple of Augustus on the Forum. In the afternoon drive to Cape Kamenjak and swim off low rocks in clear water. Save day two for the boat from Fažana to Brijuni National Park. Combine the trip with a few nights in Rovinj, half an hour's drive away.
