At this point, the river Janj splits into multiple streams with a few waterfalls. Janjske otoke are located next to the main road Sipovo-Kupres, 4 kilometers downstream from the spring of the Janj River, at 550 meters above sea level.
Janjske otoke is a location with a diverse landscape where the Janj River creates a magical appearance of this place. Multiple cascades and waterfalls of the river leave an unforgettable impression. It is a karst valley of about 1 km long and about 300 m wide. It is a magnificent landscape of renaissance parks where lush greenery is intertwined with clear streams, bubbling and loud tufa cascades and small waterfalls of the Janj River. It is a natural wonder of the karst world, where Janj sedimented thick tufa deposits over which it splits into a large number of branches and streams only for all the water to join together again and form a high foaming waterfall that makes dew in the summer and sparkling hoar frost in the winter.
