The Riežupe Sand Caves, located near Kuldīga, represent Latvia's most extensive cave system, a testament to human endeavor and geological history. These artificial caves, carved into the region's distinctive white sandstone, stretch for approximately 2 kilometers, with 460 meters currently accessible to visitors. The caves' origins lie in the 18th and 19th centuries when the white sand was extracted for glass production. The sand was used by the Ozolnieki glass factory before World War I and later by the Iļģuciems glass factory in Riga. The mining ceased in 1939, and over time, many of the passages collapsed. Inside the caves, the temperature remains a constant +8°C (46°F) throughout the year, so a jacket is advisable. The air is heavy with the scent of sand and history. The passages lead to chambers, some of which have been given names like the Hall of Love, Hall of Faith and Hall of Hope. The caves also serve as a monitoring station for hibernating bats during the winter months, when the caves are closed to the public. A visit to the Riežupe Sand Caves offers an intriguing look into Latvia's industrial heritage and natural environment. Guided tours are available from April to October, providing insights into the caves' formation, history, and unique ecosystem.
