Dahna Cave is located above Omerovići village, at the western part of Duvno field. It has a small entrance (1x1m), hidden in a hornbeam tree forest, under a rock covered with moss. Beyond the entrance space, there is a larger hall 20m long, 6 to 7m wide and 1 to 4 meters high. The ground is covered with dirt and small stones. From there, the path goes to a narrow, low channel that has a very wet bottom and is also covered with small stones. At the end of this 15m-long channel opens the 720m-long channel, called a main or a major channel, and a smaller one 60m-long, where pottery artefacts from the Roman period were found. The total length of the cave channels is 1100m. The cave has not yet been arranged for tourist purposes, but is very attractive to archeologists, paleontologists and biospeleologists.
