Optimistic Cave

The cave was named a Natural Wonder of Ukraine in 2008. Thousands of rowdy tourists and dozens of compulsive hucksters, congested cafes, and noisy transportation would not be found here. It's as though you're floating in space! There aren't many locations like this remaining on the planet. One of them is the Optimistic Cave.

Optimistic Cave is a gypsum cave near the Ukrainian hamlet of Korolivka in Ternopil Oblast's Chortkiv Raion. Within the area, around 230 km (140 mi) of passages have been mapped. As a result, behind Mammoth Cave, Sistema Sac Actun, Jewel Cave, and Sistema Ox Bel Ha, it is the longest cave in Eurasia and the fifth-longest cave in the world. It is also the world's longest gypsum cave.

The Optimistic Cave is unique in Europe, and possibly the entire world, in that it has not been spoiled by civilization. The world's longest gypsum labyrinth. Natural beauty. One of Ukraine's must-see destinations, it was just recently introduced to tourists. Trust us when we say that this will be the most unconventional kind of physical recreation and the most thrilling journey of your life.

The cave is covered with a 2 km2 layer of Neogene era gypsum that is less than 30 meters thick (98 feet). Most passages are no more than 3 metres (10 feet) broad and 1.5 metres (5 feet) height, though they can be up to 10 metres (33 feet) tall at intersections.

Huge rainbow crystals, one-of-a-kind helictites, stalactites, and stalagmites, all found in nature rather than in museums. Big galleries, tiny passageways, and gorgeous grottoes – you won't find all of this anywhere else than in Ukraine's Optimistic Cave.
