Kaklık Cave is a fascinating natural wonder often dubbed the 'underground Pamukkale' due to its striking white travertine formations and thermal spring waters flowing through its interior. Unlike the open-air terraces of Pamukkale, Kaklık offers a subterranean experience, with cascades, pools, and lush greenery bathed in natural light filtering through a collapsed ceiling. It's a geological marvel, estimated to be over 2.5 million years old, providing a unique perspective on the region's famous calcium carbonate deposits.
Visitors consistently praise the cave's surreal beauty and the tranquil atmosphere, especially during off-peak hours when it's less crowded. Many are surprised by the vibrant green mosses and plants thriving within the cave, contrasting beautifully with the white travertines. The flowing water and small waterfalls create a soothing ambiance. However, a common theme in reviews is the strong sulfur smell at the entrance, which some find off-putting, though most note it dissipates quickly once inside. The cave's relatively small size means a visit doesn't take long, making it a good addition to a day trip.
For a comfortable visit, it's highly recommended to wear flip-flops or waterproof footwear, as the wooden boardwalks and paths inside the cave can be wet and slippery in places. Some visitors even suggest bringing an umbrella due to dripping water. While there are no food or drink facilities inside the cave itself, some reviews mention a small shop and a swimming pool area outside, though their condition varies. The cave is best visited during cooler parts of the day or off-season for a more serene experience, as it can get warm inside due to the thermal waters. Expect to spend about 30 minutes to an hour exploring the cave thoroughly.
Getting to Kaklık Cave requires some planning. It's located about 30-45 minutes drive from Pamukkale. While some visitors have managed to reach it by public transport (taking a local bus from Pamukkale to Denizli Otogar, then another local bus to Kaklık), having a rental car is by far the most convenient option. Reviewers frequently warn about the poor condition of the last few kilometers of road leading to the cave, describing them as 'awful' or 'quarry roads,' especially the final stretch through an industrial area. Despite this, the cave is generally well-signposted once you get closer to the town of Kaklık. Parking is available, though some visitors have mentioned a small parking fee.
The most frequent complaint is the strong sulfur smell, which is a natural characteristic of the thermal waters. While it's unavoidable, most visitors find it less noticeable once deeper inside the cave. Another recurring issue is the condition of the access roads; driving carefully and being prepared for rough terrain can mitigate this. Some older reviews mention issues with cleanliness of facilities like toilets, though more recent reviews are less focused on this. Occasionally, the cave's lighting might be out, so having a phone torch can be useful as a backup.
