Tell me about your favorite spots for an active(*) vacation in Belgium and/or France along the Belgium border?
(*) Active means for us: hiking - long/challenging single-day hikes are fine, preferably circular ones. Biking if not too hilly AND if safe - I'm a panicky biker who dislikes aggressive cars sharing the road with me. Culture - museums and similar that have English or German explanations. Lovely cities to visit.
Boosting welcome. We will have a car. Timeline: very late May to mid-June.
