Tuhala Witch's Well
Raplamaa
Tuhala Witch's Well is a remarkable natural karst spring located in the Tuhala karst area of Kose Parish, Harju County, Estonia. This spring is famous for its rare and dramatic overflow phenomenon, which occurs when underground water pressure rises after heavy rains, causing the spring to 'boil' and spill over with up to 100 liters of water per second. The well is part of a complex underground river system flowing beneath the karst landscape, making it a unique geological feature rather than a typical artesian spring. The area surrounding the well is rich in karst formations, including sinkholes and caves, showcasing a vibrant karst ecosystem. The site is embedded in Estonian folklore, where the overflow is attributed to witches lashing each other underground, a legend that has contributed to the well's mystique and cultural significance. Tuhala Witch's Well was voted as a "Wonder of Estonia" in 2012, highlighting its national importance. Visitors can explore the nearby natural landscape, which includes hiking trails through the karst terrain and ancient cultural sites dating back thousands of years. The water of the well is slightly brownish due to humic acids but is fed by clean bog water, adding to the ecological interest of the site. The well and its karst area are protected within the Nabala-Tuhala Nature Reserve, ensuring conservation of this unique natural phenomenon.
