The lake's name is derived from the PillerseeTal valley, known locally as the 'snowiest valley in Tyrol'.
The water is classified as drinking-water quality due to the constant circulation from underground karst springs.
The lake is a naturally occurring basin that rarely exceeds a depth of seven meters.
Its unique color is caused by suspended lime particles originating from the limestone geology of the Loferer Steinberge range.
The surrounding wetlands are a protected habitat for various indigenous aquatic plants and amphibians.
Pillersee is an emerald-green alpine lake situated at an elevation of 835 meters in the Kitzbühel Alps. The lake is fed by karst springs from the surrounding Loferer Steinberge mountains, contributing to its distinct turquoise hue. It serves as a central hub for the PillerseeTal region, offering access to integrated hiking paths and cross-country ski trails. The water temperature is generally cool, even during summer months, due to the alpine mountain runoff. A wooden walkway and boardwalk surround significant portions of the shoreline to facilitate public access. The area remains a popular destination for recreational fishing, paddleboarding, and rowing. Winter conditions typically result in the lake freezing over, allowing for snowshoeing or skating in designated zones.

Bring a windbreaker even in summer, as temperatures can drop quickly when clouds pass over the mountain peaks.
Park at the designated lakeside lots early in the morning to avoid limited space during peak summer weekends.
Water shoes are recommended for those intending to swim, as the lakebed is rocky.
Attempting to swim in the center of the lake during late afternoon when mountain thermals create strong surface chop.
The lakeside area is accessible year-round, though swimming is strictly restricted to the warmer summer months.
Respect protected wetland areas by staying on marked boardwalks; do not feed wild waterfowl.
