Run by Czech state this fantastic cave just off main road from Pisecna to Polish border, highly surprising turn onto the drive with confusing signpost (it's either too early or too late, depends which direction you coming from). Parking space at the reception building. Guided tours every hour, it takes less than 30 minutes to do the circle. If you planning to visit both caves in this area: Na Spicaku and Na Pomezi - start here, as it is much smaller cave, so you will avoid disappointment.
