Postojna cave, Postojnksa Jama

Great place to sleep, but a bit pricey for just electricity... they've turned off the water. €50 for 2 nights. And don't leave anything outside; we left our ball outside, but it was gone this morning!

We parked and slept across the road for 20 euros a night. No amenities, just trash bins. Fine for one night, though there was some traffic.

We spent the night at the first campervan site you encounter, which has electricity, water, and a toilet disposal area. It's near the cave entrance. You pay for parking at the kiosk in the large parking lot where you walk to the entrance. €12.50/24h, all-inclusive. Shuttle bus €2 per person, round trip to the castle.
