The Maaspark Ooijen-Wanssum is an area that is newly designed in 2020 with channels and depressions in numerous places. These ensure a better flow of the Meuse during high water. The walking tour goes through part of the climate buffer 't Sohr, which was built in 2012, an old Meuse meander that is now part of the more than 500 hectares largest continuous area with Maas nature in North Limburg. In Blitterswijck, the remainder of Blitterswijck Castle is visited, what remains are pieces of wall that remain. Blitterswijck Castle was a castle from the 14th century, the castle was blown up in November 1944 by retreating German soldiers. Until 1820, Hooge Heide was part of an extensive heathland area that was later planted with trees because drifting sand threatened the surrounding villages. The Groote Molenbeek flows on the edge of Meerlo, with Meerlo Castle as its landmark, also known as 't Kasteelke. It is a so-called castle farm that was founded in 1619. It is presumably older, as it was largely destroyed by fire during the 80-year war.
