Korallgrottan, Marble cave in Ankarvattnet, Sweden
The cave system extends over 6 kilometers through bands of marble, featuring numerous chambers with formations shaped by water over thousands of years.
The Swedish Speleological Society discovered the cave system in 1985, leading to its designation as a nature reserve and Natura 2000 area in 1994.
The Swedish name Korallgrottan refers to the small speleothems inside the cave that resemble coral structures throughout the underground passages.
Guided tours operate from Midsummer to August on Tuesdays, Wednesdays, and Saturdays at 10 AM, with an entrance fee of 1345 SEK for adults.
The cave maintains a constant temperature of 4 degrees Celsius, and its stalactites grow at a rate of only one centimeter per thousand years.
