Hiking Tour: “Sonnschienalm via Grüner See”

posted in: Hiking, Moderate, Outdoor, Photos, Summer | 0

A very nice tour around the “Grüner See” (green lake) up to the “Sonnschienalm”, especially promising in spring or early summer when the karst lake is filled with cold but very clean melt water from the surrounding mountains.

Promising tour around the “Grüner See” (green lake) up to the “Sonnschienalm”

The tour starts at the “Grüner See” (green lake) which is a karst lake located in Tragöß-Sankt Kathrein (Styria). This lake fills up slowly with melt-water from the surrounding mountains and thus is very clear but also very cold (5-6°C). The water-level heavily depends on the season: it reaches its maximum level in early summer (around 10 m) but nearly dries out in fall.

Tip: The current water-level is tracked on this website.
Please note that the tour is very much exposed to sun, don’t forget proper sun protection (hat, sun screen)!

Interesting background information

The lake’s unique blue-green color results from:

  • the fact that clear water absorbs the red portions of light
  • the lake itself is surrounded by mountains and therefore protected from wind and thus there are no waves on the surface
  • the soil beneath is mostly chalk and thus no floating particles are set out into the water
