Wilderness Landscape & Natural Heritage
The Kaali Crater Area is a significant geological site located on Saaremaa, the largest island in Estonia. The area is distinguished by an array of meteorite impact craters, with the largest being about 110 meters in diameter and 22 meters deep. Formed approximately 3,500 years ago, the craters were caused by an iron meteorite that fragmented upon entry into the Earth's atmosphere. The impact is one of the few known to have occurred in a populated area, making it historically important. Visitors can explore the main crater, which has a picturesque pond often surrounded by dense forest and a walking path that offers insights into this ancient cosmic event. The Kaali Crater Area is not only a geological wonder but also an archaeological site, with ancient fortifications nearby that indicate the historical significance of the region. Visitors are drawn to the area not only for its scientific interest but also for the rich culture and natural beauty of Saaremaa.
