of Ploučnice Gulley
Monumental Ploučnice Gulley is actually a large water-gang with two tunnels, which was used by neighboring mills and damed up by sluice-gates. Watermen who dare into it usually scratch their canoes' bottoms, but also may see pseudokarst caves in a rift between the two tunnels and many traces telling about former function and origin of this interesting underground and live a small but pretty adventure sometimes followed by tumbling out at the final weir. We who walk inside on feet have to wade and hold walls on slippery places, but it is always worth it.
