The lake was specifically constructed to store water for the snow-making systems that supply the Ahorn ski slopes in winter.
It is positioned on the sunny side of the Zillertal valley, providing a direct view of the high-alpine peaks of the Zillertal Alps.
The water clarity is maintained by a specialized natural filtration system, avoiding the use of chemical additives.
The area surrounding the lake was designed with a focus on accessibility, featuring level paths suitable for strollers and wheelchairs.
The lake serves as a central hub for the 'Ahorn Leisure Mountain' concept, which includes nearby bird of prey viewing areas.
Ahornsee is an artificial mountain lake located at 1,965 meters above sea level on the Ahorn plateau in the Zillertal Alps. It serves as both a recreational swimming destination and a water reservoir for snowmaking operations on the Ahorn ski mountain. The lake is purpose-built with a depth of approximately 8 meters and occupies an area of about 15,000 square meters. It is surrounded by a flat wooden promenade and expansive grassy areas for sunbathing. The water temperature fluctuates significantly based on alpine weather conditions, typically remaining cool throughout the summer. The location is integrated into the Mayrhofner Bergbahnen mountain infrastructure.

Bring a windbreaker or warm layer, as the high altitude causes rapid temperature drops once the sun dips behind the peaks.
Pack a high-SPF sunscreen, as UV radiation is significantly stronger at nearly 2,000 meters than in the valley.
Combine your visit with the nearby eagle and owl flight demonstration to maximize your time on the plateau.
Assuming the water will be warm; it is mountain water and remains quite cold even during peak summer.
Open exclusively during the summer cable car operating season; inaccessible once the Ahornbahn closes for the transition to winter sports.
No diving from the designated promenade; follow local signage regarding water safety and restricted areas.
