Cycling in Mullerthal & Little Switzerland
Cycling in the Mullerthal: Luxembourg's Little Switzerland — 112 catalogued climbs through limestone gorges, ancient beech forests, and rock formations on perfectly surfaced roads.
The Mullerthal gets its "Little Switzerland" designation from the drama of its landscape rather than any elevation superlative — the limestone formations, narrow gorge passages, and dense beech and oak forest create a visual intensity that feels disproportionate to the actual altitude, which tops out at 428m on the Pétzbierg. For cyclists, this translates into a region where the climbs are shorter and more technical than the Ardennes to the northwest but arrive in a setting of exceptional natural beauty: the Ernz Noire gorge, the Berdorf plateau, and the wooded approaches to Echternach deliver a cycling aesthetic that northern European destinations rarely provide.

Best Cycling Climbs in Mullerthal & Little Switzerland
Beaufort Loop Climb
6km · 250m · 4.2% · CAT3
The Beaufort Loop Climb is the longest ascent in the Mullerthal region — 6km from the Black Ernz valley floor at 140m to the Beaufort plateau at 390m, making it the most sustained aerobic effort in an area otherwise defined by shorter, sharper climbs like the Petzbierg and the Mullerthal Gorge. At 4.2% average with 8% maximum, the gradient is moderate throughout: this is a pacing and aerobic capacity test rather than a pure power challenge, and its Cat 3 classification reflects the cumulative 250m of elevation gain over distance rather than any section of extreme steepness. The road begins from Beaufort village at valley level — the medieval castle ruins of Beaufort (a different complex from Bourscheid, smaller but equally well-preserved) visible above the treeline on the left bank of the Black Ernz stream — and climbs through a forest corridor of exceptional density and character: mature oak and beech trees of old-growth scale that close the road canopy from approximately km 1 to km 4.5, creating a cool, enclosed cycling environment unique in the Mullerthal. The Black Ernz stream accompanies the road for the first 2km, its sound audible from the tarmac in the deeply enclosed lower valley before the road separates from the watercourse and the gradient increases marginally for the upper forest section. The 8% maximum arrives on a straight section at km 4 where the forest begins to thin and the plateau agriculture comes into view — a 400m sustained push before the road levels for the final approach to Beaufort plateau village at 390m. The summit plateau connects to the Berdorf cycling network and the Schapbachpass descent, making the Beaufort Loop the natural entry point to a broader Mullerthal circuit for riders approaching from the south or west.
Mullerthal Gorge Climb
1.1km · 90m · 8.1% · CAT3
The Mullerthal Gorge Climb rises directly from the Ernz Noire stream at the base of the limestone formations — the most dramatic section of the Mullerthal landscape — on a road that transitions from a shaded gorge floor to an open plateau in 1.1km of concentrated effort. The 8.1% average is raised by a distinct 13% ramp at the 700m point where the road exits the gorge enclosure and the gradient bites hard in the final exposed section before the Berdorf plateau. The enclosed lower section passes beneath limestone overhangs and through dense beech canopy; in spring, water seeps from the rock faces and the road surface is damp even in dry weather, requiring particular attention to traction in the early season. This is the climb at the heart of the Mullerthal Classics Tour and the one most directly framed by the region's signature geological character — the limestone formations that gave the area its "Little Switzerland" designation are at their most impressive in the gorge immediately below the climb's start.
Pétzbierg (from Hinkel)
1.4km · 130m · 9.2% · CAT2
The Pétzbierg from Hinkel is the Mullerthal's hardest climb and Luxembourg's second most demanding ascent after Mont St. Nicolas — 1.4km at 9.2% average reaching 15% maximum on the critical central section. The approach from the hamlet of Hinkel follows a narrow lane through dense beech forest, the enclosed character of the climb concentrating the gradient's impact in a way that more open roads cannot match. At 1.4km, the climb is short enough to tempt an explosive opening effort, but the 9.2% average and the 15% ramp around the mid-point punish that approach severely: this is a climb that rewards measured, rhythmic power from the first pedal stroke. The summit at 428m — the highest point in the Mullerthal region — is marked by a small clearing where the forest opens briefly before the descent toward Berdorf. The Pétzbierg appears in the Mullerthal Classics Tour route and is the standard benchmark test for riders assessing their form in the region.
Schapbachpass
2.8km · 160m · 5.7% · CAT3
The Schapbachpass is the Mullerthal's most accessible significant climb and the one best suited to riders seeking panoramic reward alongside gradient challenge — at 2.8km and 5.7% average, it is longer and more sustained than the Pétzbierg without reaching the same peak severity, and the summit at 380m provides the finest views in the eastern Luxembourg region: the Sure valley, the German Eifel plateau, and on clear days the distant Ardennes high ground to the northwest. The climb approaches from the Sure valley floor through mixed agricultural land before entering a forest corridor for the upper third, where the gradient steadies at 7–8% and the road surface improves markedly. The Schapbachpass is used in the Tour de Luxembourg on stages crossing between the Moselle valley and the Mullerthal, and its combination of manageable gradient and scenic reward makes it the natural "first climb of the day" introduction to the region.
