It was a solid downpour in Lake Bled on our last full day in Slovenia so we decided to drive to the Postojna Caves. We are so glad we did! Perfect for a rainy fall day, we got in the English speaking line (they have audio headsets in other languages) and boarded an open car train. IT IS COLD! Make sure you where gloves and a jacket or you might not appreciate the incredible magnitude and vision of these caves. There is a 1.5 (?) km walk that is a bit steep so if you have mobility issues you can take a shorter version I think. Words cannot express the beauty. The stalagmites and Stalactites are magical and the ceilings high above. The guide was there to answer questions when we got out of the train. There was adequate time to take pictures. Yes, you can take pictures but NO Flash. Don't miss these caves! (Eat a Black Cave Burger when you get out at the cafe. Delicious!
