Sutinščica is the longest cave in Zagorje with 254 metres (0.158 mi) of explored passage, and is located in the southern foothills of the Ivanščica massif. Its depth is 5.5 metres (18 ft), but its total vertical difference is 13.5 metres (44 ft). It is a mostly horizontal cave, so its horizontal length of 229 metres (751 ft) is close to its total length. Part of the cave is seasonally dry, while part requires specialised equipment. The opening keyhole passage opens up into a series of chambers, while the permanently submerged section further back remains unexplored.
