Pilatusbierg via Rue des Grottes

At just 1.1km, Pilatusbierg via Rue des Grottes is short but deceptively intense — 90m of elevation packed into a brief, breathless effort. The average gradient of 8.4% disguises ramps of 19.3% — the kind of gradient that turns plans into prayers. The 3 hairpin turns break up the climb, each one revealing a new perspective on the road ahead. Located in Luxembourg, Luxembourg.
