Gokgol Cave

This cave is located in the Uzulmez region, right on the side of the Zonguldak - Ankara highway. Water coming out of the cave pours into the Uzulmez Valley. The entrance of the cave is wide and high between the blocks of rocks. About 250 m from the entrance starts a siphon. Although siphon is 10 m long, it can be passed by walking during the summer season when water is drawn back. Once the siphon is passed, you enter an underground valley. A yellow mud brought by the flood waters accumulate on the floor of the valley and it is possible to see some accumulated water. After this point the cave splits into two branches that pass through extremely rich and beautiful formations. 3200 m long cave progresses in curves. Although the rivers and internal lakes can be easily passed by walking, sudden floods can happen during heavy raining. Because of this potential danger the cave expeditions must be done in summer and autumn seasons.

Kizilalma Cave

The cave is located in Zonguldak province, Gelik region, Ayici Village, Kizilelma district and can be easily reached by a vehicle. The waters of Aydin and Buyuk Ay valleys sink into an active ponor opening. The entrance to the cave is through a 30x10 m fossil opening on top and water starts about 100 m ahead. The cave progresses along with water in a horizontal direction. After the first 100 m, the next 400 m can be passed crawling. At the end of these 400 m pathway there is a siphon. This siphon can be passed during autumn seasons. After passing the siphon the tunnel in the cave becomes very huge.

About 3200 m ahead in the cave that basically continues as a single active tunnel, there is a sky opening 80 m high that is intense enough to illuminate the lake at the bottom. The cave continues for another three kilometers with lakes and ends up with two siphons. The water from here was determined to come out from Cumayani Cave.

Inagzi Cave

This cave is in Zonguldak province, inside the city, on the 15th km of Kilimli Road, on the coast of the city. The fossil entrance of the cave is facing the sea and the cave is 800 m long in total. After 50 m, the passage becomes only wide enough for one person to pass and continues as a runlet at some places. 400 m ahead there is a siphon that can be crossed by walking during summer seasons. The cave then continues for another 400 meters and ends up with a siphon.

Cumayani Cave

The cave is located in the Cumayani region, three kilometers away from the Catalagzi ditrict. It is a part of the Kizilelma- Cumayani underground water system and has many opening to the outside. The tunnel can be reached either by walking 100 m form the entrance where the water comes out or walking 75 m from the dry entrance on top. The tunnel starts with an incredibly beautiful Travertine that plays the role of a bridge on the underground valley. 60 m high, 70 m long tunnel has a thick layer of mud on its floor and ends with a siphon. If you walk to the left from the Travertine, in the direction of the water flow you’ll reach siphon in the Kizilelma Cave direction. You’ll need a boat in this tunnel.

Due to sudden floods during rain seasons or unexpected heavy raining the cave imposes a life threatening danger.
