The Riežupes smilšu alas (Sand Caves of Riezupe) are despite the name no caves, they are sand stone mines. The soft quarz sandstone was mined for four generation to produce glass, the fine sand it consists of is very pure and the produced glass is of high quality. The mine is home to eight species of bats, as a result it is closed duruing winter to protect the bats.

The small mine is located in a romantic valley with dense forests. It is named after the brook Riežupe, which flows into Venta river only 500 m from the mine.
