We had a great day with our guide Simona, who told us so much about Slovenia and the places we visited. The Postojna caves were really impressive, the best I have seen. The Predjama castle is in an interesting location, but there is little to see inside. Piran is a beautiful little town. We first had lunch at the sea front, and then had a walk around the town with Simona.
