Three things people keep getting wrong

· Plopsaqua Hasselt — frequently listed, does not exist. Belgium's Plopsaqua waterparks are at De Panne and Hannut-Landen only.

· Klimcentrum Bleau is in Ghent, not Genk. Don't drive east looking for it.

· Thermae 2000 Valkenburg shows up on every spa list. From Slagmolen it's ~40-45 km — a half-day commitment, not a stop on the way to dinner [84].

· Lommelse Sahara sits just outside the 30 km arc at ~44 km — beautiful, worth it on a separate day [59].
