Yurievskaya Cave, Natural monument cave in Bogorodskie Mountains, Tatarstan

Yurievskaya Cave is a natural monument in the Bogorodskie Mountains, formed in dolomite rather than limestone. Its passages and halls hold gypsum blind wells up to 4 m deep and 0.5 m wide, gypsum remnants resembling stalactites, and shelf-like ledges overhanging the floor. The cave's mapped length reached 990 m by September 2010.

A. V. Stupishin made the first survey in 1953, recording a cave 20 m long with an area of 58 m². In May 1971, newcomers of the Kazan speleological section cleared a pile of stones and entered a new part over 360 m long. Resurveys by Naberezhnye Chelny speleologists with the Ural Speleological Association in 2008–2009 brought the mapped length to 507 m, and excavations by the Kazan section in 2010 opened a large new section, reaching 990 m by September 2010.

The cave lies in the Bogorodskie Mountains near Tenishevo, in Tatarstan's Kamsko-Ustyinsky district, and since 1986 has been a regional nature monument (IUCN category III). It is the only cave in Tatarstan open to tourism, and a safe descent has been built at the entrance, with a visitor centre planned.

The underground passages require sturdy footwear and warm layers, as conditions are cool and surfaces can be slippery throughout the year. Bring reliable lighting since navigating through the interior relies on artificial light sources to move safely through the passages.

The cave's gypsum forms blind wells up to 4 m deep and 0.5 m wide, plus stalactite-like remnants and shelf-shaped ledges overhanging the floor. Larger wells and remnants reach 3.5 m across and 2–3 m high, shaped by gypsum dissolution rather than limestone.
