Everyone can taste a Trapist beer but why would you not taste a Trapist beer in a Abbaye such as Orval http://www.orval.be/en/home//
I studied there for short period for a intensive period before exams, several years...successfully ..;playing Ping pong with the monks ;-)) and "trying" new beers.
Now you can't but you will feel the Middle Age atmosphere.
Try & drink (and eat their chees)
Go and see the amazing nature in the surrounds (Florenville on the French border is a city you can visit also).
