Diana, a guest from San Franciso asked what to see on their drive from Split to Dubrovnik.
Regarding stopping on the way to Dubrovnik from Split – absolutely the Peljesac Peninsula is worth a visit. Ston is a medieval town, with reputedly the longest fortified wall outside the Great Wall of China. They are famous for mussels in Ston and for wine in the peninsula. Depending on how much time you have, you can drive all the way to the end, Orebic, then take a ferry to Korcula and from there to Dubrovnik. But this makes for a very long day.
For wineries in just 1 day, it is hard to pick, but I would suggest the following best of the area:
Milos Winery – a small winery in Ston, which produces only a couple of varieties, but best in class
Saint Hills winery in Oskurosno – do the tour and lunch – be sure to try the Dingac
Korte Katarina in Orebic – we like the rose and Posip white particularly
There are lots of good family Konobas to try the local oysters & clams and beaches along the way from Ston to Orebic, the nicest are in Orebic. If you feel adventurous and want to stay overnight in Orebic, look for signs for Sobe – this means room for rent. We do this a lot and have always had a good experience. You should be able to find a place, which has a nice balcony, on or near the sea. Ask to see the rooms and take your pick. Most will not have pools, but will be in old Croatian style, which we find charming.
