Col de la Haute Levée

Mountain Pass

29.7 km

The east side of the ascent of the Rosier is known as the variant. It is the shortest of the three, but the most intense. The climb starts in the beautiful town of Ruy, quietly located far away from the crowds. The start is very easy to find, follow the signs Spa/Andrimont.

Immediately after the start, the most difficult part of the ascent begins. At the bottom, the climb taps serious percentages. At the beautiful Gîte de Chevrouheid, children often play in a river when the weather is warm. You are free to turn around at the top to go under as well. Fortunately, you drive here through a beautiful forest that provides some extra cooling.

If the road goes to the left it gets a lot easier. Take a good rest here, because as soon as you reach the first houses of the village of Andrimont, the percentages go up again. Winding through the village you can make up the intermediate score. You are only two kilometers on the road and you still have half of it. If you're already having a hard time, the road is still long.

And that second half consists of a very long, slightly ascending road. You feel it is almost nothing, but you still climb around 5% here. After a lot of raking you finally reach the T-junction where the easy long runner Le Rosier from La Gleize comes out on the left and the aesthetic Le Rosier from Spa on the right.

Route de Borgoumont Climb

Highlight (Segment) • Climb

This road is superb! With wide, unobstructed views of the surrounding hills, forests, and hamlets. A typical landscape of the Belgian Ardennes.

Coo Waterfall

Highlight • Waterfall

The waterfall is one of the highest in Belgium with a drop of 15 meters. There is a staircase between the two waterfalls, from where you can admire the impressive flow of water masses. The falls are a tourist attraction so there are a few cafes nearby.

Côte de Mont-le-Soie Climb

Highlight (Segment) • Climb

The first left-hand bend and the subsequent 600 m are already rising at around 8%. Then it gets a little flatter. But after 1 km it gets steeper again with up to 10%. That was the worst part and the last 2 km are only 5% on average.
Average gradient: 6%
Difference in level: 247 m
