Kaprun Mooserboden Reservoirs

The Mooserboden and Wasserfallboden reservoirs form part of the Kaprun high-mountain hydropower system operated by Verbund. Built between 1938 and 1955, the facility harnesses glacial meltwater in the High Tauern mountains to generate renewable electricity. The Mooserboden dam itself stands at 107 meters high and 500 meters long, while the lower Wasserfallboden dam complements energy storage in a pumped-storage configuration. Together they feed the Limberg I and II power stations, which contribute over 800 megawatts to Austria’s electricity grid. The project is notable for its ambitious engineering in a high-alpine environment, including an inclined elevator and a system of tunnels and penstocks bored into the mountain. It also reflects a complex socio-historical legacy, having been initiated under Nazi rule using forced labor and later completed as a symbol of Austrian postwar reconstruction. Today, the site combines hydroelectric infrastructure with environmental education, offering a rare opportunity to explore operating reservoirs and internal dam galleries at over 2,000 meters altitude.

The site is open to visitors from late May through mid-October, weather permitting. Access begins at the Kesselfall Alpenhaus, where a ticketed journey includes a bus transfer through tunnels and the Lärchwand inclined lift — Europe’s largest open funicular. At the top, visitors can explore the Mooserboden dam area, the "Electricity Adventure World" exhibition, and guided dam tours offered several times daily. Tour duration is approximately 45 minutes and includes entry into the interior of the Mooserboden dam. Entry to the dam zone is included in the ascent fare; guided tours require a small additional fee. There are also themed trails, panoramic viewpoints, and a mountaintop restaurant with indoor and terrace seating. Warm clothing and sturdy shoes are recommended due to changing weather conditions at altitude. Groups and schools may book educational packages in advance. Facilities are generally wheelchair accessible, though parts of the inclined lift and dam walk may present limitations.
