Way to the thickest fir in the world

The thickest fir tree in the world has a trunk diameter of 1.84 meters and a volume of 22 cubic meters of wood. The more than 300-year-old giant tree enjoys excellent health. The magnificent specimen stands above St. Martin in the Calfeisental and can be reached within 40 minutes on a well-marked, somewhat steep path. Coordinates: 745 945/198 919, 1575 m a.s.l.

Further to discover: St. Martin is a 700-year-old Walser settlement steeped in history and legends, which was inhabited all year round until 1652. Today, the place is lovingly maintained and is a real insider tip for excursions.

Knowledge: Fir trees in the Swiss Plateau usually reach a diameter of 60 to 80 centimetres and have a volume of 8 cubic metres of wood. Although fir trees often grow much taller than those in the Calfeisental (32.8 metres), this is probably the thickest, according to the Swiss Federal Research Institute WSL. In the Slovak primeval forests, a red fir with a diameter of 1.78 meters is known and another fir in Bosnia has a diameter of 1.7 meters.
