I visited this WHS in April 2014 by ferry boat from Split. I took the slow ferry since I decided to go by car for the day. The catamaran service takes 1hr instead of 1hr 45mins but it inly carries passengers and its schedule is only convenient if you intend to sleep on Hvar island. I had a fabulous hotel room in Split so I took the slow ferry departing from Split at 08:30 and coming back from Hvar island at 17:30. If you travel by car, make sure you're waiting at the jetty at least 1 hour before otherwise you risk not finding a space. The ferry trip was smooth and we passed by Brac island before arriving at Hvar island. The view of Split from the higher deck is worth seeing too. The ferry arrives at Stari Grad harbour which is 5-10minutes by car from Stari Grad Old Town. There's a free parking lot just outside the town which is where I left my car. The old town itself has UNESCO funded information boards illustrating the things to look out for and giving a brief overview of the historic importance and cultural value of the site. The whole loop took around an hour in which I saw some mosaics, a couple of chapels and churches, hill forts, a medieval tower and a mill. Skor Square and the Church of St. Stephen were the highlights of the old town. Then I drove in the narrow country roads with rubble walls, olive trees and vineyards to different viewpoints and I must say that the highlight there was the panoramic view of countless vineyards and lavender fields on rolling hills going down towards the blue sea in Brusje. Afterwards I drove to the other side of the island about 30 minutes away on a well-paved winding road to Hvar Old Town. It turned out to be a worthwhile trip since it was still low season and still quiet compared to the summer months when this place is overcrowded with people wanting to enjoy the beach or the summer parties. Hvar's 16th century Venetian-era hilltop castle offers fantastic views of the harbour below. The highlight of our trip to Hvar was undoubtedly the fresh "seafood buzara" we ate at Gariful, a chic restaurant along the waterfront.
