Demirköy is a town in Eastern Thrace, northwestern Turkey.
Demirköy, literally "iron village", is a small town surrounded by forests up on the lush Istranca Mountains, in northeastern Thrace, not far from Black Sea coast (which lies roughly 25 km to east).
- Demirköy Foundry. Dating back to Byzantine period, and then restored by the Ottomans in 1400s, this is the place which lends the town its name and is where the cannons used in Ottoman siege of Constantinople of 1453 (i.e. Fall of Constantinople) were cast.

Perhaps the most fascinating cave in Eastern Thrace, Dupnisa Cave (Dupnisa Mağarası) lies around 25 km southwest of Demirköy, deep in the forest. (Take the road signposted with a brown Dupnisa Mağarasısign, which branches off at the 15th km of Demirköy-Pınarhisar road, also with a connection from the centre of Demirköy. After about 5 km, you'll pass through the village of village of Balabanlı, with another somewhat decrepit and semi-illegible sign towardsDupnisa; from this point on the cave is 21 km away. On the way, you will pass through the village of Sarpdere, where the road turns into a gravel one, which lasts for 5 km until Dupnisa.) Opened to tourism in 2005, though at the cost of hundreds of bats who called there home and part of the bed of underground creek which formed the cave in the first place, it is pretty much possible to easily visit a 400-m section of this 2-km long cave.
The cave has two entrances, with the main one opening to what is called "wet cave" (ıslak mağara or sulu mağara), due to the underground creek flowing through here. A 250-m concrete and siderailed path, in addition to bright illuminations let visitors to have a smooth stroll here, without getting their feet wet even with a single drop of water. This part of the cave is still pretty much in forming stage, with most vertical surfaces covered with surreal-looking stalactites. The rest of the wet cave, in which creek flows all along and some underground lakes up to 2 m deep can be found, is only open to cavers who know what they are doing.
At the end of the path through the wet cave start the concrete stairs—this is the part of the cave that is called "dry cave" (kuru mağara), and you will inevitably meet some bats here, just don't panic and don't scare them off. After a quite demanding walk up for about 150 m and seeing some more stalactites, you will reach back to ground level (actually 30 m higher in elevation than the entrance of wet cave). From here, instead of going back in, you may return by following the waymarked trail through the forest to the main entrance, which takes around 15 minutes on foot.
Ancients used to conduct rituals—involving human sacrifice—to their most respected god (of wine), Dionysos (originally Thracian but later came to be known for his seat at Greek pantheon in the much wider part of the world) in Dupnisa. There is a theory that the very name of Dionysos evolved from Dupnisa, or Nyssa, the other name the cave was known by in ancient times.
The temperature of the cave ranges between +10° and 17°C year-round, so pack along appropriately.
Wet cave is open 15 May-15 Nov 9AM-sunset, while dry cave is open year round 9AM-sunset. 2 TL pp. The surrounding forest is a popular weekend retreat for locals, so can be a little bit crowded especially during spring and summer months. Basic snacks—such as corn on the cob, cheese pancake, and grilled sausages—can also be obtained from vendors in the surrounding area during weekends.
