Roesbrugge: 7,8 km. Starting at the bridge over the river IJzer in Roesbrugge, this walk explores the frontier landscape along the winding river. Most of the hike (three quarters) is along traffic-free paths such as pretty church trails and grassy paths. A nature exploitation path follows the Zwijnbeek, de Ijzer and the Heidebeek, thus making the soggy pastureland along the border more accessible. The landscape is undulating, open and offers some amazing views. Thanks to their rich, cultural heritage, remarkable history and many inns.
