Passage 309: Discovering Rhine Migration
Explore Rhine River biodiversity at Passage 309: Witness fish migration and learn about river ecology in Gambsheim.
Passage 309, also known as the Gambsheim fish ladder, provides a unique opportunity to witness and understand the importance of fish migration in the Rhine River. Inaugurated in 2006, this site is one of the largest fish passages in Europe, facilitating the movement of approximately 60,000 fish annually. The attraction features a visitor center with exhibits detailing the biodiversity of the Rhine, the impact of river development, and the function of fish ladders. An underwater viewing room with large windows allows visitors to observe fish as they navigate the ladder. The experience is both educational and engaging, suitable for adults and families. Passage 309 is located at the Rhine's 309th kilometer mark, hence the name. The site is part of a Franco-German project that includes a river lock and a hydroelectric power plant, highlighting the region's blend of ecological concerns and industrial activity. The fish ladder helps restore the salmon population, which was abundant before the construction of locks hindered fish migration. While the visitor center is compact, it offers comprehensive information in multiple languages, including French, German, and English. Visitors can also download the Foxie treasure hunt app for a more interactive experience. Special guided tours provide access to the inner workings of the fishway, offering insights into its technical operations and the challenges of maintaining river ecosystems. Note that the Passage 309 visitor center has limited and varying opening times. It is recommended to check the official website before planning a visit.
