Near the Jachthuis St. Hubertus in the national parc Hoge Veluwe as from today the large pond was safe enough to ice skate (last night -21C=-6F!!). They swept a track of I think 800 meters and because you have to pay to enter the parc and it's not close to larger cities, it was still quiet. I went there with my daughters (we have an annual pass) and skated over 2 hours. The first time of my life. So great to skate in beautiful nature!
