Sy and Logne loop from Bomal

This 18.5 km loop offers a very varied route between valleys, villages and rocky ridges.
The route begins with a rapid climb from Bomal towards the Bomal viewpoint , the first significant ascent. This is followed by a series of descents and climbs leading to Ozo.
The central section then runs along the Ourthe valley before reaching Logne and Palogne.
The second half of the route is more demanding, with a steep climb towards the Sy ridges , followed by more uneven terrain before the return to Bomal.

Departure and start of the hike

The hike starts in Bomal, at the bottom of the valley.
The first few kilometers quickly gain altitude with a sustained climb leading to the Bomal viewpoint, offering an unobstructed view of the Ourthe valley.

Points of interest along the route

  • Bomal – starting and finishing point of the loop.
  • Bomal viewpoint – first viewpoint after a marked climb.
  • Ozo – village crossed after a succession of valleys.
  • The Ourthe – river followed on a gentler section of the route.
  • Logne – passage through the valley before the ascent.
  • Palogne – a site known for its ruins and natural environment.
  • Crêtes de Sy – highest point and most spectacular section of the route.
  • Sy – a village nestled at the foot of the rocks.
  • Herbet – hamlet passed through before the final return.

Return to the starting point

After Herbet, the trail alternates between wooded sections and more open paths, before gradually descending towards Bomal, where the loop closes.
