“This is a fantastic tour if you don't have much time and want to see two amazing places in Slovenia: lake Bled and the Postojna cave. It's nearly 11 hours long and thus quite tiring, since the lake and the cave are pretty much in the opposite direction when leaving from Ljubljana, but it's definitely worth it as they are both amazing. The guides were very good and professional, picking us up near the hotel and explaining many things along the way. The bus was actually a little van, so not too much space if you have bags, but we were only a small group so it was fine. Definitely…”
