The walk starts at the Provincial Domain De Schorre, which is world-famous for Tomorrowland. (During major events at De Schorre, you cannot do this walk because parts of the route are closed off for security reasons).
What is now a green oasis used to be one of the many brick factories with clay pits and smoking chimneys. To transport the clay to the brick ovens along the Rupel, the streets were underground. There are still about fifty tunnels that are now being restored one by one. Do you want to look for a few? As a bonus, you might also find a couple of trolls.

You can't get lost because you follow walking junctions. These are indicated in the text with their number as RIV... (from Rivierenland, some signs still mention Scheldeland).

You start in the parking lot of the Provincial Domain De Schorre in Boom. Follow the footpath in the middle of the parking lot, away from the street, to a small tower, an elevator, and a staircase. There, you go down and turn left until you reach a roundabout (RIV102).

Go here almost straight over a small bridge. After a second bridge, you arrive at a building that was once part of the brick factory and now houses a conference center and an indoor adventure park. There, you turn left, between the building and the pond.

Take the rising path. Just before the end of the pond, you will see a first brick factory tunnel on your right.

Continue walking along the wooden path until you reach the 25-meter-high monument 'One World by People of Tomorrow'. This was designed in 2014 by the Belgian artist Arne Quinze in celebration of the ten-year anniversary of the world festival. It represents the Nike of Samothrace, a statue from classical antiquity that symbolizes the victory of freedom. The wooden bridge itself contains more than 210,000 messages from all over the world. If you have plenty of time, you can try to find one of the marriage proposals or the message from then UN Secretary-General Ban Ki-moon.

At the monument, you turn right and follow the wooden path with the old clay pit on your left until the next walking junction RIV110.

There, you turn right down the stairs, or you walk straight slightly uphill and bending right along the road with the concrete ovals. Both paths reach the walking junction RIV200 at the top. On your right, you see the delta meadow. This is the site of the main stage of Tomorrowland and where delta gliders regularly soar down the slope. To your right on the slope, you see a couple of trolls, but you'll get closer to them shortly.

You now walk along the asphalt path between an antenna mast on the left and the delta meadow on the right. You follow in the direction of the beautiful giant trolls made from recycled wood from the brick factories. In total, you can find 7 trolls in this provincial domain.

You continue to RIV199. Stay walking straight in the forest towards RIV103. The asphalt path turns into a sandy road that gently descends to the right via a series of steps. You come down past a small clay pit on your right, and if you look closely, you'll notice a troll standing somewhere keeping an eye on you. Don't get distracted, because you need to turn left a little further on.

You follow a boardwalk, and after 100 meters, you reach a T-junction with another boardwalk. If you look closely here, you can see a piece of a barefoot walking path. Turn left here. After the boardwalk, continue walking straight. At an open spot a bit further on your left side, it's a double hit: a brick factory tunnel AND a gigantic troll.

The walking path turns right here, and you pass the start of the 'Barefoot Path'. You continue to follow the signs to the next walking junction. After two small bridges, you arrive at a small intersection with walking junction RIV103. Here you turn left, and past the parking lot, go straight towards RIV201.

You walk between the sports fields and quickly reach a brick factory tunnel. This runs under the road connecting the two brick-making municipalities of Terhagen and Boom. You walk straight, and after 300 meters, you arrive at the cycling museum De Velodroom and the inevitable cyclist café De Musette.

At the dike, you turn left and pass several businesses established on the sites of the former brick factories. Follow the dike until you reach the brick factory museum Rupelklei.

Turn left there at junction RIV98. You quickly reach RIV269 at a bend in the road. Continue straight on Kloosterstraat towards RIV161. You end up on the main street of Terhagen. Carefully cross that and turn left.

After a short while, you will see on your right a restored wall of the former brick factory NV De Beuckelaer. Go through the access gate and take the stairs on the left. A little further, it’s again a left turn until you reach RIV161.

There you continue straight. When you return to the main street, turn right until the next walking junction RIV276. There, you also continue straight on the road. You pass several dead-end alleys filled with workers' housing.

At the Mazda garage, cross the street again (be careful as this is at a bend). Follow Polder until a T-junction where you turn right. Just past RIV202, you arrive back at RIV201.

Now you follow the dike in the other direction, downstream towards Boom. But be careful because the Rupel is a tidal river. Every day there are two high and low tides with the flow direction changing. It may be that you walk against the stream. But don't let that throw you off, just keep following the dike. Walking junction RIV100 is the next destination. Along the way, you will pass a restored historic house 't Steencaeycken, now a café with social employment (highly recommended!). If you step off the dike there, you'll find the Nautical Visitor Center Rupelstreek just a bit further. Here, you can learn about the history of shipbuilding in the Rupel region in relation to the brick factories. The center is built in and around the stone barge 'Clotilde', the last sailing clipper (also highly recommended).

But your path continues along the dike, which takes a detour past a boatyard. You pass beautiful graffiti. Those graffiti animal motifs can be found all over the region on old buildings.

You arrive at the street where the wooden pole of RIV100 is on the left, but here you turn right and follow the narrow street. Past the houses, you can clearly see that both left and right everything was excavated for the small industry in the past. A little further, you spot a chapel on the right. If the foliage allows, you will see on both sides of the street a brick factory tunnel that goes under the main street. You cross that busy road and follow the walking path straight beside the sports fields until RIV244.

From here, it's just a bit longer straight to the parking lot where you started.
