Turkey
An underground river opens into a cathedral-sized cavern holding Turkey's largest underground lake.
The boat glides forward into blackness. Stalactites materialise in the torchlight, their reflections doubling in water so still it looks like glass. Then the cavern opens: a cathedral-sized chamber where an underground river has pooled into one of the longest cave lakes on Earth, and you stop paddling and just stare.
Altınbeşik Cave sits in the western Taurus near Akseki, inside a national park of pine and cedar forest. It holds Turkey's largest underground lake, cited among the three longest subterranean lakes in the world, and the visit is by small boat across water that ends at a 44-metre travertine barrier. Boats run in summer and autumn only; in winter and spring, meltwater raises the lake and the cave closes. The name means Golden Cradle, after a formation near the entrance, and the walk in through the gorge of the Manavgat headwaters is nearly as dramatic as the cave.
Solo
The boat ride into the cave is contemplative, almost meditative: silence, scale and darkness in equal measure. The surrounding mountain trails extend the day.
Couple
Gliding together across an underground lake in near-silence, stalactites lit above and reflected below, is an otherworldly shared moment. The boats hold few passengers.
Friends
Pair the underground lake with the Taurus trails above, then grill trout over pine embers and compare notes on what you saw in the dark.
