Harmankaya Waterfalls 

You can descend to the valley, where the Harmankaya Waterfalls (Harmankaya Şelaleleri) in the city centre of Zonguldak are located, through a narrow path in the forest. In most parts of the valley, there are paths that are 10 meters wide. After an average of 1,100 meters of hiking in the valley, you can see the first waterfall. After an uphill climb just past the first waterfall, proceed 20 meters on the path between the bushes and descend to the valley, at the top of the first waterfall flow. Another 250 meters from this spot is the second waterfall. Here, after a 30-meter climb in the forest next to the waterfall, you will walk down a 20-meter path and see the second waterfall. After walking a little further in the valley, you will come to the third waterfall. Lush green flora surrounds visitors along this trail. In the forest area within the valley, you may come across plants and trees such as chestnut, oak, hornbeam, linden, buxus, cranberry, alder, poplar, plane, blackberry, arbutus, wild apple, wild cherry, wild hazelnuts, bay, medlar, wild grapes, rowanberry, wild pear, rhododendron, blackberry, and rosehip.
