Kottlasjön

Can you imagine a lake once deemed so pristine it served as a city’s reserve water supply? That’s Kottlasjön for you. This beautiful lake, nestled in the southern part of Lidingö, is a testament to the changing times and the enduring allure of nature. Kottlasjön is connected to Stockbysjön in the north by Stockbyån and drains southward through Mölnaån, eventually flowing out to Lilla Värtan. This intricate network of waterways was once a hub of activity, with Mölnaån even boasting a mill and a copper hammer mill in its time. Kottlasjön held a special significance until the 1950s as Lidingö’s backup water supply. Swimming was allowed, but only sparingly. The water treatment plant, located in “malpåse”, served as a reminder of the lake’s importance. However, the presence of a nearby paint factory in the past raised concerns about the water quality in the 1990s. Today, Kottlasjön is no longer a reserve water source, but it is still a cherished spot for recreation. When winter graces Stockholm, Kottlasjön transforms into a magical ice-skating rink. A cleared path invites locals and visitors to glide across its frozen surface, enjoying the crisp air and the picturesque surroundings. Although it’s a popular activity, remember that the ice thickness can vary, so caution is always advised. Kottlasjön isn’t just a pretty sight. It’s a living testament to Lidingö’s history. As you stand here, breathing in the fresh air, know that you are standing on the precipice of time, where the echoes of the past mingle with the vibrancy of the present.
