Mitterastensee is a small alpine lake tucked away at 2228 m above sea level in the heart of the Goldberg Group. Though modest in size — just 90 m long and 40 m wide — it offers a peaceful, untouched setting that feels far removed from the busier trails of the region.

The lake sits on the eastern slopes of the Gasteiner Höhe, between the peaks of Mitterastenkopf (2401 m) and Kalkbretterkopf (2412 m). It has the character of a natural, shallow pond with flat shores, and a small fen stretches along its southern bank. The surrounding landscape is classic high-alpine terrain — sparse vegetation, rocky slopes, and open views toward neighboring summits. In summer the area attracts hikers seeking quiet, scenic walks, while in winter and spring access becomes far more limited due to mountain conditions.

How to get there

• Starting point near Bad Hofgastein — mountain trail, moderate difficulty
• Alternative approach possible from Vorderschneeberg

Practical information

• South of the lake lies a chamois resting zone, closed to visitors from December 1 to May 31
• The lake holds significant ecological and scientific value, home to the rare rotifer species Cephalodella doryphora

Small as it is, this lake hides a remarkable natural treasure — its waters shelter a rare microorganism found in only a handful of places worldwide.
