In the beginning of April we visited again this more than 2 km long water cave. In order to get into it a wetsuit is needed, because one has to crawl for a few tenths of meters in the narrow passage filled with small underground river. However, after that the cave opens and there are some interesting flowstone formations to admire. The cave ends up with a sump to which a channel leads with so low ceiling, that someplace one have to duck under the water in order to go on (see the last picture taken a year before).
