Orlova Chuka

Orlova Chuka is a cave situated in the Danubian Plain, north-eastern Bulgaria. With a total length of more than 13 kilometers, the Orlova Chuka Cave is Bulgaria's second-longest cave. It was discovered in 1941 and opened to the public in 1957.

Visitors can now go through nearly 3 kilometers of hallways, corridors, and tunnels. Visitors can enjoy calcite crystals, stalactites, and sinter formations in this accessible section, which is lighted.

The Orlova Chuka was constructed during the late Pliocene and early Quaternary periods, when it was the bed of a subterranean river cut out of the local limestone and sandstone sedimentary rocks. The cave is made up of a maze of tunnels and chambers. Because of the subterranean eddies, the ceiling is mostly smooth.

The Concert Hall, the Big Stalagnate, the Little Chasm, and the Golemite Sipei Hall, the cave's largest hall, are the cave's principal attractions. The sinter lake Izvorcheto (the Spring) and its white stalagmites are another notable site.
