Gökgöl Cave is a 350-million-year-old dripstone cave located in the Üzülmez area of Zonguldak. It features an 875-meter illuminated walking path filled with stalactite and stalagmite formations, alongside an underground stream.
Gökgöl Cave is located right along the main highway to Ankara in the Üzülmez area, close to the center of Zonguldak. Dating back to the Carboniferous period, this dripstone cave is estimated to be around 350 million years old. Spanning a total length of 3,350 meters, it is the tenth-longest cave in Turkey and the second-longest in Zonguldak. The section open to visitors consists of an 875-meter illuminated boardwalk. The remainder of the cave is either unexplored or requires specialized caving equipment.
Inside, magnificent stalactite, stalagmite, and column formations alternate between dense clusters and wide chambers. An underground stream flows along the cave bed, keeping the air noticeably cool and humid. Visitors recommend bringing a light jacket or sweater and wearing sturdy sneakers, as the floor can be slippery in places. Reviews note that lighting is generally good, though it dims slightly along the final 50 meters of the path.
According to local legend, the cave was discovered accidentally by a shepherd looking for his lost sheep. Facilities at the entrance include a parking lot, a small cafe, restrooms, and a prayer room. Parking space is limited, so short delays can occur during peak hours. Overall, it offers a comfortable excursion for families, and children can easily complete the walkable platform.

When to Visit?
Because the cave temperature stays cool year-round, the best time to visit largely depends on outdoor weather conditions. For those escaping summer heat, the cave offers pleasant natural cooling. In winter, the temperature difference between indoors and outdoors is much less noticeable. The cave is reported to be open daily, so visiting on weekdays gives you a better chance of avoiding crowds.
How to Get There?
The cave is located on the right side of the Zonguldak-Ankara highway near the city entrance. Just follow the signs. Visitors traveling by private vehicle can park directly in the parking lot. Those using public transport can take an intercity bus to Zonguldak and transfer to minibuses running towards Ereğli. The drive takes about 4.5–5 hours from Istanbul and around 3 hours from Ankara.
How Long Does a Visit Take?
Exploring the 875-meter walking path at a relaxed pace takes about 1 to 1.5 hours. Photographers may spend extra time, as visitors frequently stop at areas dense with stalactite and stalagmite formations. You can also add a short break at the cafe near the entrance to your itinerary.
Things to Know Before You Go
Inside the cave, conditions remain cool and damp year-round, so bringing a light layer of clothing is recommended. Wear sneakers with good grip as the floor can be slippery in places. Visitors note that lighting decreases in the final 50-meter section, where a small flashlight could come in handy. Parking capacity is limited, so expect possible wait times on weekends and public holidays.
Best Photo Spots
The most picturesque areas are in the first and middle sections of the cave, where stalactites and stalagmites are dense and lighting is strong. Playful interactions of light and shadow stand out around column formations. The underground stream flowing along the cave bed also makes for an interesting photographic detail.
