The nature park of the valleys of Burdinale and Mehaigne is a traffic-calmed area in French Haspengouw, with numerous climbs around the river valleys of the Méhaigne and Burdinale rivers. The starting point is the parking lot of the former Fumal train station. The former railway line is now an asphalted bike path.

The first part of the route features a series of steep climbs: towards Wanzoul (max. 14%), from the Abbey Val Notre-Dame (steep at 17%) and through the Bois de Champia (initially reaching about 20%). After the initial climb towards Wanzoul, you pass a sandstone quarry; at the quarry, the road is poor and partially unpaved (over a distance of 100 meters).

After that, the route leads over the Haspengouw plateau, where, typical of Haspengouw, a lot of farming is conducted. Here, the climbs are less long, but some streams have created relief (up to 30 meters of elevation change).

After about 33 km, you reach Fumal again, near the starting point (100 meters away), but then you climb out of the Mehaigne valley again via the beautiful Côte de Marneffe. The descent to Fallais is initially gently sloping (with a not-so-good road surface), but in the steeper part of the descent, the road surface is good. Down below, 100 meters from the thoroughfare, lies the beautiful castle of Fallais.

Now comes another climb and descent into the Mehaigne valley, and you reach the high plateaus of Haspengouw again, with its typical concrete roads. You now cross into the valley of the Burdinale River. This river has a much deeper valley than the Mehaigne has carved out. Then you repeatedly climb out of the Burdinale valley and descend again, following the course of the Burdinale downstream. Here, too, there are sometimes climbs with steeper sections, such as the climb from Oteppe along the castle, which reaches 17% at the beginning in the village.

The ride ends on the asphalted bike path that runs along a former railway line through the Mehaigne valley. The asphalt is good in this part (but laid out somewhat hilly). However, to access this bike path, you have to strangely ride several hundred meters on a poor asphalt road, which is also unpaved for about fifty meters (but is still passable).

The roads in this area are mostly of good quality, except for the three poorer sections mentioned above (as of November 2019). However, the concrete roads on the Haspengouw plateaus can be muddy after rainy periods and during harvest time, as primarily agricultural traffic uses these roads and can wash sand from the surrounding fields (in the absence of ditches along the fields).

The number of elevation meters recorded by my Garmin Edge 800 is 1100 hm, over 200 hm more than routeyou.com indicates!
