Strėvos įgriuva

Strėvos įgriuva is a natural sinkhole in Aukštadvaris Regional Park, featuring steep-sided walls that descend to a basin floor surrounded by forest. The depression spans several hundred meters across and is accessible through a marked walking route.

The sinkhole formed during the ice age when glacial deposits buried a detached ice block that melted away, leaving behind the sunken depression visible today. This geological formation reflects the dramatic landscape changes that shaped the region millennia ago.

Local folklore tells of a tavern that sank into the earth during a supernatural celebration, and this legend continues to shape how people think about the place today. The story remains part of the region's storytelling tradition and connects visitors to the land's mythological past.

A marked walking trail provides easy access to the sinkhole with several information stations and an observation platform along the route. Wear sturdy shoes since the slopes are steep and can become slippery, especially after rain.

The floor of the sinkhole holds a thick peat layer that has accumulated over thousands of years, supporting unusual plant species adapted to the moist, shaded environment. This creates a microhabitat quite different from the surrounding forest.
