The best gravel rides around Héron

One of the most beautiful Adeps walks, along the Bocq and the railway line, 95% in the woods, just hard enough.

At the end of 2025, the urban planning permit for the renovation of the castle and its outbuildings was granted. It will be a large-scale restoration project – the complete renovation of the main castle and the improvement of the facades and roofs – aiming to breathe new life into this 17th-century gem, classified as exceptional heritage of Wallonia. The project includes the operation of the castle as a large guest house, combining historical preservation with public access. During my visit in July 2026, it was clearly visible that the works had started: there were construction containers along the driveway, where there was quite a bit of activity. source: haltinne.be

The domain of the Haltinne castle covers 279.98 ha of agricultural land, forests and meadows. The 'Struviaux' stream and several springs supply water to four ponds and the castle's moat. From an architectural point of view, the Haltinne castle is an exceptional heritage. Its appearance today is the same as when it was built in the mid-1600s. The imposing towers, loopholes and moat are reminiscent of a military function, but this is indeed a castle farm. Not only the facades, roofs and moat, but also the castle's monumental staircase are protected as exceptional heritage of Wallonia. This stone staircase has steps two meters wide, with a wide handrail also in stone. The massive character of this staircase contrasts with the statuettes representing the allegories of the four seasons. The wrought iron gate originally intended for King Leopold II and the 'Ciergnon' castle, the false windows in the east tower and the barn with a straw roof consisting of round limestone pillars are some other points of interest of the castle, which is however not publicly accessible. source: haltinne.be

This RAVeL follows the old railway line 127, which once ran from Hannut to Huccorgne. The RAVeL winds through the heart of Hesbaye, past grain fields and orchards, and through villages like Villers-le-Peuplier and Avennes, before ending in the Burdinale and Mehaigne Valley Nature Park.

Excavations are conducted year-round at Moha Castle, making it unique in Belgium. When I visited, two archaeologists were uncovering a wall that runs beneath the visible castle and likely dates back to the 12th century.

The castle is free to visit. At the foot of the rock, there's a visitor center where you can pick up a badge to open the gate. For €4, you can also get a brochure with information about the most important points. The castle is only open to visitors starting in April, but the friendly man at the visitor center let me in on February 27th... as far as you can even call it "inside" at this ruin ;-)

The fortified tower, situated on the edge of the Fosseroule stream and defending the valley, is considered a peripheral bastion of Moha Castle, located a mile and a half away. Agricultural and residential buildings form an enclosed complex, built between the 17th and 19th centuries. In the eastern corner stands an imposing tower, built of limestone rubble, with a square plan (16th century) on a wider, sloping base. This tower originates from an earlier structure, the cellars of which have also been preserved. The openings were modified, and in the 17th century, the tower was extended on the south side with a bay of limestone rubble and brick, reaching the limits of the original structure. To the west of the tower stands a two-story house, perpendicular to the tower, built of limestone rubble, probably dating from the 17th century. Source: bibliotheca.wanze.be

Please note that the second part of the walk is inaccessible due to the quarry expansion. There are no signs indicating the direction of travel. A sign from the town indicates the change in the local road where you rejoin the trail. Information should be provided at each end to avoid unnecessary backtracking.
