Kölnbrein Reservoir, reservoir in Kärnten, Austria
The Kölnbrein Reservoir is a large body of water in the Austrian Alps held back by a concrete dam approximately 200 meters (660 feet) tall. The installation includes multiple dams and tunnel systems that transport water between different elevations and use it for electricity generation.
The dam was constructed in the 1970s to store water for electricity generation and supply power to the region. Shortly after completion, cracks appeared in the structure, which engineers repaired through extensive reinforcement work to ensure the installation's safety and longevity.
The reservoir's name reflects its connection to the surrounding mountain landscape and the local tradition of hydroelectric power generation. Today, visitors can observe how the installation is woven into the region's daily life and how people use the location for recreation and exploration.
The site is best reached via the Malta High Alpine Road, a scenic 14-kilometer route with tunnels and curves open from June through October. Visitors will find parking areas, hiking trails, and small restaurants on-site; a guided tour through the facility or a walk across the viewing platform atop the dam provides detailed insight.
A distinctive horseshoe-shaped bridge called the Skywalk extends over the water, allowing visitors to stand above the valley and look down. This bridge also serves as a bungee jumping point on special weekends, adding an element of adventure to the location.
