Hrustovačka pećina, Prehistoric cave in Federation of Bosnia and Herzegovina.

Hrustovačka pećina opens in the Strane hill above the spring of the Glibaja stream, about 700 metres by village path from Hrustovo. Its entrance is a large opening in the rock, and the high vaulted interior branches into two arms: a wide, walkable western passage about 480 metres long and a narrower southeastern passage about 760 metres long ending at a small lake. Near the centre, stalactites and stalagmites form shapes compared to a lion, an elephant and totem poles.

Excavations by the Zemaljski muzej in Sarajevo in the early 20th century found eight large prehistoric hearths at the cave entrance, along with animal bones and pottery. The finds belong to the Vučedol culture, and the regional variant in Bosnia is named the Hrustovački tip after the cave. Probing also uncovered bones of a cave bear that lived here 60,000 years ago.

The cave's archaeological finds gave their name to the Hrustovački tip, a regional variant of the Vučedol culture in Bosnia and Herzegovina. Excavations at the entrance yielded eight large prehistoric hearths, animal bones and pottery such as belly-shaped amphorae, biconical bowls and cups on cross-shaped feet, decorated with stamped triangles, rectangles and zigzag bands.

The entrance is accessible without fees or restrictions, but visitors should bring a flashlight and wear sturdy shoes for safety. Inside conditions can be slippery and dark, making proper gear essential for a comfortable visit.

The cave appeared in the TV show Joko gegen Klaas – Das Duell um die Welt: in the fourth episode Klaas was to find one of the lakes and fill a bottle with water there, but he failed to locate the lake.
