More ways to explore the area's outdoor wonders
You step down into a cavern where light thins and the air cools to a steady 12°C — the Slănic salt mine opens like a quiet cathedral of stone and crystallized mineral. At 208 meters deep, galleries flare into chambers with bases some 32 meters wide and column heights reaching 55 meters; you can hear your footsteps and, if you listen, the faint echo of generations who carved these rooms by hand.
