Tulumtaş Cave

Tulumtaş Cave is a fossil cave in Tulumtaş Mahallesi, within Ankara’s Gölbaşı district, in the Karayatak area beside the Ankara Ring Road. Its story begins in 1992, when dynamite blasting at a stone quarry during road construction exposed an underground space that had not been planned as a visitor attraction. That origin distinguishes Tulumtaş from caves reached through traditional exploration: modern transport infrastructure revealed this geological pocket. Today, the place brings together a quarry-discovery story and a protected interior landscape, giving a Gölbaşı outing a specific connection to Ankara’s recent physical development and its limestone setting. Ankara'nın Gölbaşı ilçesinde, Tulumtaş Mahallesi sınırlarında, Karayatak bölgesinde ve Ankara Çevre Yolu kenarında bulunur. 1992 yılında Ankara Çevre Yolu yapımı sırasında kullanılan taş ocağında yapılan dinamit patlatması sonucu keşfedildi. Tulumtaş Cave is in Tulumtaş Mahallesi, in Ankara’s Gölbaşı district, in the Karayatak area beside the Ankara Ring Road. It was discovered in 1992, when dynamite blasting at a stone quarry during construction of the Ankara Ring Road exposed the cave.

The cave is classified as a fossil cave and measures 549 metres in total when its side passages are included. Along the route, visitors encounter several distinct limestone formations: stalactites descending from the ceiling, stalagmites rising from the floor, and columns formed where deposits have joined. Flowstone and rimstone add wider mineral surfaces and edges to the scene. The variety matters more than a single monumental chamber: Tulumtaş rewards attention to changing textures, repeated mineral shapes and the relationship between the arranged visitor path and the older rock environment. Its interior temperature is approximately 10–11°C throughout the year.

Plan about one hour for a comfortable visit, allowing additional time if geology interests you or if you want to examine the formations carefully. The 549-metre figure includes side passages, while the visitor experience follows an arranged route with viewing points and careful walking rather than an unrestricted expedition through every metre. Tulumtaş can therefore work as a focused stop within a wider Gölbaşı day, or as the main purpose of a shorter excursion from Ankara. Build in enough time to pause over stalactites, stalagmites, columns, flowstone and rimstone instead of rushing from entrance to exit.

The most dependable seasonal feature of Tulumtaş Cave is its stable underground temperature, approximately 10–11°C throughout the year. The cool interior creates a marked contrast with Ankara’s summer surface conditions and remains noticeable when outdoor weather changes. Carry a light extra layer in every season, especially if the cave is one stop in a longer day around Gölbaşı. The cave’s setting beside the Ankara Ring Road also gives the visit a distinctive rhythm: a journey through a developed transport corridor leads into a much older geological environment below ground.

No ticket price, free-admission category or separate charge should therefore be treated as established here. The cave’s location, discovery history and geological features are documented, but the practical admission field remains deliberately empty so an unsupported figure is not presented as current visitor information.

By private car, travel from central Ankara towards Gölbaşı on Konya Road, D750, then follow the Tulumtaş direction signs. The cave is in Tulumtaş Mahallesi’s Karayatak area, beside the Ankara Ring Road. A municipality visitor shuttle was reported in 2023 from points outside TOKİ Clock Tower and Gölbaşı Public Library; that is historical information, not a current service claim. For a present-day journey, use the road approach or the named local bus corridor as the planning basis.

The cave stays approximately 10–11°C year-round, so a light extra layer is useful even on a hot Ankara day. Inside, keep to the arranged visitor route, walk carefully and avoid touching stalactites, stalagmites, columns, flowstone or rimstone; these formations are the geological focus of the visit and should remain undisturbed.

Tulumtaş Cave offers detail-led photographic subjects rather than a broad landscape panorama. Stalactites, stalagmites, columns, flowstone and rimstone create layered lines, edges and mineral textures along the route, while the steady 10–11°C interior gives the scene a consistent cool atmosphere. Images can highlight the contrast between the cave’s enclosed geology and the modern Ankara Ring Road setting above it, or focus tightly on repeating formations and the arranged path. Keep movement discreet in the confined space, stay on the route and never use a formation as a prop or touch point. The quarry-discovery context can also shape a visual sequence from infrastructure to underground geology.
