12km – Challenging.
Unexpectedly epic! From a high-tech exhibition in Boulaide to the rocky heights of the Houfels, this Eislek Pad is full of surprises: public art, steep climbs, acorn-strewn paths and sweeping views over the Upper Sûre.
In the mid- 1950s, an entire photo exhibition went "viral". And it is still going strong today, permanently displayed in a handsome castle in Luxembourg. So what did my kids make of it?
