Stari Grad Plain is an hard to get UNESCO site, the hardest of the croatian sites and even if you manage to go to Stari Grad, it won't be easy to get cards, that's what Agata says. Agata also says that the town is very beautiful.
Stari Grad is a town on the northern side of the island of Hvar in Dalmatia, Croatia. One of the oldest towns in Europe, its position at the end of a long, protected bay and next to prime agricultural land, has long made it attractive for human settlement. Stari Grad is also a municipality within the Split-Dalmatia County.
The most ancient part of Stari Grad falls within the UNESCO Protected World Heritage Site of the Stari Grad Plain, while the entire municipality lies within the surrounding buffer zone. - in: wikipedia
