The former town hall is truly beautiful! From the side, it initially looks like a church, but from the front, you can see the typically Dutch brick gable, richly decorated with lion heads.

A small pond in the middle of the forest. There's a bench on one side for a quick rest. A bridge crosses the pond. A very beautiful, unexpected place.

In the Bos Elfbergen lies a beautiful pond that you can admire from an idyllic wooden bridge. This largest forest in Gaasterland, created in the 19th century, offers a mix of deciduous and coniferous trees that give the whole a fairytale atmosphere. Walk or cycle along the winding paths and enjoy the peace, the view of the water and the surrounding nature.

Balk has a rich history, dating back to the Middle Ages. The village developed along the Luts, a historic river that was traditionally important for shipping. In the 19th century, Balk became a centre of the dairy industry, and the village flourished due to the many farms that processed their products here. This heritage is still visible in the authentic buildings and the rural character of the village.

An atmospheric path that winds through the dense trees of the Rysterbosk. This wooded area offers quiet walking routes along stately oaks and beeches, where the light falls beautifully through the canopy. Ideal for a relaxing walk in nature, with alternating views of open spaces and densely wooded areas.
