Quick Facts

Discovery Story and What to See Inside the Cave

The Hedgehog's Discovery

The cave's rise to prominence dates back to 1999. The popular tale goes that a shepherd, tending his animals, followed a hedgehog into a narrow opening in the rocks and discovered a deep void below. Following the news, researchers explored the galleries; the area was registered as a nature monument in 2013 and declared a nature park in 2021. After the installation of walking platforms, railings, and lighting, the cave was opened to visitors. Ceramic fragments found within the cave indicate that the space was used in much earlier periods. The name Gilindire comes from Aydıncık's ancient name: the city of Kelenderis evolved over centuries into Kilindra and Gilindire, with the district adopting its current name in 1965.

The Descent and the Stalactite Gallery

Your visit begins with a long descent down iron staircases from the entrance. You'll go down 46 meters relative to the entrance to reach the gallery floor, with the number of steps varying in sources, ranging from 351 to 560. As you descend, the outside heat fades, humidity rises, and the gallery expands. Stalactites hanging from the ceiling, stalagmites rising from the floor, columns, curtain formations, and cave needles are all visible in intricate detail thanks to the lighting. Since the ground can be damp, wearing non-slip shoes and holding onto the handrail will make your journey easier.

Aynalıgöl: The Underground Lake and a Glacial Era Record

At the deepest part of the gallery lies the lake that gives the cave its name, approximately 140 meters long and up to 47 meters deep in places. The upper 15 meters of water are fresh, while deeper layers are saline; as the lake's elevation is approximately 47 meters below sea level, it's believed the system is connected to the sea. Submerged stalactites and stalagmites, isolated from atmospheric effects, preserve climate and sea-level data from the last glacial period; for this reason, the cave is considered one of the few recording sites in the Eastern Mediterranean shedding light on this era. In the windless section, the water's surface remains perfectly still, reflecting the formations on the ceiling. Visitors observe from a platform by the lake; entering the water and venturing beyond the platform are restricted to preserve the site.

How to Get to Aydıncık and the Cave

1. By Air: The two main gateways to the region are Adana and Gazipaşa-Alanya airports; from either, you can rent a car and connect to the D400 highway.
2. By Road from the East: From Mersin or Silifke, head west, reaching Aydıncık via Taşucu and Yeşilovacık.
3. By Road from the West: Those coming from the Alanya-Gazipaşa route will use the same coastal road via Anamur.
4. Public Transport: Bus and minibus lines operating between Silifke and Anamur stop in Aydıncık; from the town center, a short 7.5 km transfer by car takes you to the cave.
5. Final Stretch: The connecting road off the main highway is narrow and winding. Search for the cave's name on navigation and plan your visit during daylight hours, factoring in closing times (7 PM in summer, 5 PM in winter).

Best Time to Visit and Seasonal Comparison

Since the cave's interior remains cool and humid year-round, the determining factor is primarily the outside weather and road conditions.

Combining the Cave with Aydıncık's Coastline

Before a road connection was established to Sancak Burnu, where the cave opens, it was only accessible by boat. This same rocky coastline is excellent for snorkeling today. Spending the morning underground and dedicating the afternoon to the sea is a popular itinerary; coves can be reached by coastal road or boat. Those looking to combine water sports with bay exploration can choose from nature and adventure tours.

Nearby Stops and a Two-Day Itinerary

The Aydıncık Axis: Kelenderis and the Coast

Kelenderis, whose name lives on in the district as "Gilindire," is an ancient port settlement on the coast of the district center; the city's name dates back to 5th-century BC records. Harbor ruins, floor mosaics, and foundations of sea-facing structures can be seen in the area; it easily fits into the same day as your cave visit. Those planning an itinerary centered around ancient cities can explore cultural tours options.

East and West: From Silifke to Anamur

For those heading east, Silifke, the sinkholes around Narlıkuyu, and Kızkalesi, known for its castle in the sea, are on the itinerary. To the west, visitors will find the ancient city of Anemurium near Anamur and Kayacı Valley, famous for its hiking trails. Those wishing to venture inland from the coast can cross the Taurus Mountains and head towards Karaman's attractions. In a two-day plan, the first day covers the cave and Aydıncık's coast, while the second day explores stops either to the east or west.

Local Flavors and Where to Stay

Highlights of Mersin Cuisine

Tantuni and liver wraps are popular everyday choices; on the sweet side, cezerye and kerebiç are local specialties, while künefe is a common post-dinner treat. In coastal towns, the fresh catch of the day features prominently on menus. Those planning a food-focused trip can explore gastronomy and event tours options.

Accommodation Options

Aydıncık center offers small-scale hotels, apartment rentals, and guesthouses. Those seeking wider options can consider Silifke and Taşucu, while those looking for tranquility might prefer the bay resorts around Yeşilovacık; Anamur on the western end is also suitable for an overnight stay. During summer and public holidays, coastal capacity is limited, so book your stay in advance.

Practical Tips Before You Go & Itinerary Summary

• The stairs are steep, and the ground can be damp; opt for non-slip shoes.
• The cave interior is cool year-round; even in mid-summer, a light outer layer is useful.
• Last entries are taken before closing (7 PM in summer, 5 PM in winter); confirm hours before setting out.
• Those with knee, heart, or respiratory conditions should consider the exertion of hundreds of steps up and down.
• Photography in low light is challenging; a steady hand and a wide-aperture lens will improve results.
• Markets and ATMs are limited nearby; carry water and cash (card payments are also accepted at the ticket office).
