The travertine terraces are formed by the rapid precipitation of calcium carbonate from mineral-rich thermal springs.
Unlike Pamukkale, this site is largely unrefined and maintains a more rugged, natural landscape.
The water source feeding the travertines has a distinct sulfuric scent due to the high mineral composition of the underground reservoir.
The site is located within a forested transition zone between the Black Sea and Central Anatolian climate regions.
Akkaya Travertenleri features natural mineral-rich carbonate deposits located near the village of Çepni in Bolu, Turkey. These white, terraced formations are created by calcified spring water flowing over sloping terrain, creating pools similar to Pamukkale but on a smaller, localized scale. The site is situated along the Mudurnu road, approximately 10 kilometers from the center of Bolu. Water within the pools is known for its high mineral content, including sulfur, which is often associated with local therapeutic properties. The park area includes walking paths that allow visitors to observe the geological formations. It functions as a public outdoor destination primarily popular for photography and nature observation. The geological structure is actively evolving as mineral-rich water continues to deposit calcium carbonate layers.
The upper viewing platform offers a panoramic perspective of the white terraced pools against the green forest backdrop.
Wear sturdy, non-slip footwear as the calcium deposits and wet surfaces can be extremely slippery.
Bring a change of clothes if you intend to wade in the pools, as the mineral-heavy water can leave residue on fabrics.
Visit on a weekday to avoid crowds, as the limited space on the walkways becomes congested during weekends.
Attempting to climb or touch sensitive areas of the white rock, as the mineral crust is brittle and can be damaged by foot traffic.
Respect the fragile geological structures by staying on marked paths and avoiding walking directly on active, thin crusts.
