The Katjasee is highly recommended. The water is very clear and a beautiful turquoise. A hike here is definitely worth it.

First of all: Lake Helene is a place that makes the heart of every nature lover beat faster. As a relic of a former opencast mine, this lake offers an impressive panorama and a deep history. Once referred to as the "bathtub of Frankfurt", Lake Helene in times past attracted up to 120,000 bathers daily seeking the freshness and clarity of the water. But, as is sometimes the case, such wonderful places also hide their own secrets and challenges. Due to repeated embankment slides, bathing operations were stopped in the entire northern area of the lake - a scenario that makes the hearts of bathing lovers heavy. The extent of the landslides is so significant that extensive investigations and drilling up to 40 meters deep are currently being carried out to ensure the stability of the lake. The consequences of these changes are noticeable. Large events such as the famous Helenebeach festival have to pause and it is uncertain when the swimming season can resume. According to forecasts, this could not happen before 2026. But in the midst of these challenges, people's resilience and innovative spirit are also evident. Despite all the adversities, the surrounding area and campsites remain open, smaller events are organized and visitors are invited to enjoy the vastness and tranquility of the area. The history of Lake Helene goes back a long way - it emerged from the former "Helene" brown coal mine, which was operated from 1943 to 1958. After it closed, the open pit filled with groundwater and became the scenic body of water we know today. While it has repeatedly faced landslides and closures in recent decades, Lake Helene remains an impressive testament to the past and a place that must be protected and preserved. For all cyclists and nature lovers: Even if jumping into the cool water is currently not possible, Lake Helene still offers a picturesque backdrop and pure relaxation. It's always worth a stop - be it to admire the breathtaking nature, find out about the history of the lake or simply to enjoy a moment of peace.
