just rent a bike and enjoy
i think it's one of best things (sporty somehow!) that you can do in Croatia, just rent a bike and follow the road by seaside..and breath..breath..this wonderful pine trees smell along the way.. and enjoy these breathtaking sunsets.. to find rent a bike is not a problem in croatia, prices are approx. the same everywhere
