Nature is at its most beautiful in the early morning. Wake up to the first rays of sunlight shining through the treetops, drops of mist glistening on the leaves and the birdsong in the morning light. With the ranger you can take a nice walk through and around the Formerumer forest. The Formerumerbos was once created to prevent the dunes from dominating the area. Many different types of trees were planted, making this now one of the most varied forests on Terschelling. Many birds are found here, such as great spotted woodpecker, willow warbler, siskin, tree creeper, various species of tits and buzzard. The forest is also rich in mushrooms. On the east side of the Formerumer forest lies the Liesinger Plak, a wet dune valley. You can see many water birds here, but also natterjack toad and various plant species. The tour starts at 8:00 AM in September and at 8:30 AM in October. Duration of the excursion is 1.5 hours. Min. participation 4 people.
