Hollow ways are typical small landscape elements in hilly areas with a loess subsoil. Most hollow ways presumably originated in the Middle Ages. Centuries of use of the same path, on foot or by horse and cart, led to a natural erosion process. Hollow ways therefore carry a piece of history with them and are thus part of our cultural heritage.

In the Neigembos, nature is allowed to evolve almost spontaneously. The trees can grow old and there is a lot of dead wood. Due to the danger of falling branches, it is important to stay on the paths. There is a rich plant growth: on the more acidic soils you will find mainly bracken, lily of the valley and woodruff. On the more loamy soils, you can enjoy wild hyacinth, wood anemone, wild garlic and yellow dead-nettle in the spring. The western part of the forest reserve, also known as the Vriezenbos, consists of, among other things, a spring forest with typical species such as black alder, common ash, marsh marigold, giant horsetail, bitter cress and the two species of lesser celandine. Enjoy the natural beauty with the help of the three mapped-out walks: the Dikke Beukenwandeling, the Bevingenwandeling and the Groebenwandeling. (Agentschap Natuur en Bos)

In the Kluisbos - on top of the 141-meter-high Kluisberg - you'll never run out of walking or cycling opportunities. This is the largest forest in the Flemish Ardennes.

My bank account is often pretty bare at the end of the month, but the urge to gamble is still there. You know how it is when you want to play, but your budget isn't cooperating. I've spent hours scouring voucher websites, which mostly just show junk or expired codes. Then I found a tip in a small forum that sounded promising. I clicked on the link for the Playfina Casino no deposit bonus https://playfinacasinowin.net/nodeposit/ without having high hopes. But hey, it worked! I was actually able to start without making a deposit. Sure, you don't become a millionaire overnight, but it was perfect for testing the new Pragmatic Play slots. It's just fair not to have to buy a pig in a poke, especially here in Germany.

Crowded, but still very nice and quiet, you do not feel like being in Vlaanderen.

The Sint-Pietersbos is the eastern extension of the Muziekbos. This former private forest covers over 52 hectares. The Muziekbos (50 hectares) was almost completely clear-cut during the First World War, but the Sint-Pietersbos was preserved. It boasts a unique collection of old summer oaks and American oaks, beeches, and ash trees, all 150 years old. (City of Ronse)
