Long-distance hiking trails pass through the most beautiful parts of Belgium, passing through nature reserves with forests, country lanes, and other rural elements. A GR trail is a multi-day hiking route that connects various regions. It is recognizable by its white and red markings. Several routes run through Beersel.
GR 12 connects Amsterdam via Brussels to Paris over a distance of approximately 1,000 km: three European capitals on a single hiking trail. The Flemish section (263 km) from Bergen op Zoom to Braine-le-Château is a surprisingly varied and green hiking trail that includes not only Brussels and Antwerp, but also cities such as Lier and Mechelen.

GR 512 runs in an east-west direction straight through the Belgian province of Flemish Brabant for 176 kilometers. The starting point is the fascinating East Brabant provincial town of Diest. It is a journey full of surprising variety, combining forests, rolling fields, protected nature reserves, character villages, and imposing medieval castles and farm estates. At the end lies another colorful provincial town: Geraardsbergen. In fact, the trek ends just across the East Flemish provincial border. You can do the trek in two directions. With a distance of 176 km, the trail is easy to hike in 4 to 8 days, depending on your walking pace.

The Streek-GR Groene Gordel takes you on a long 145 km loop all the way around the Brussels region through three sub-regions of Flemish Brabant: the Pajottenland, the Brabantse Kouters, and the Dijleland. It is a surprisingly green route through the heart of the country, featuring knightly castles, beautiful forests, authentic pubs, and rolling fields. The great advantage of the trail is the frequent and good connections – even on weekends – to the center of Brussels. The entire Streek-GR is therefore perfect for hiking in 9 daily stages.
