Protected cycle path (gravel). Essentially a straight line from Oelegem to Sint Job in 't Goor (connecting with the Schoten Canal). Despite its straightness, it's not endless and offers plenty of variety.

Het Zwart Water is a nature reserve southwest of the town of Lichtaart, which is part of the Antwerp municipality of Kasterlee, located near Lavendelweg 1-3. The area is managed by the Agency for Nature and Forests. The area is located on the Kempense Heuvelrug and consists of a fen that used to be in a drifting sand and heathland area, but was largely forested with conifers during the 19th century. On the edge of the fen you will find bog myrtle thickets, willow swamp forest and poor grassland. There is a floating dome in the fen that forms a safe resting place for birds. The forest is gradually being transformed into more mixed forest. In addition, there are remnants of heathland.

The name "Vrieselhof" goes back to Jan van Vriesele, a nobleman from Kontich who bought approximately 24 hectares of land in Oelegem around 1300 (approximately 32 hectares). In 1975, a year after the sale to the province of Antwerp, the domain was opened to hikers. From 1977 to 1999 the "Provincial Textile and Costume Museum" was located in the Vrieselhof. Due to a lack of resources, only a limited part of the collection could be exhibited. In 2002, the museum moved to Antwerp and was named Fashion Museum Antwerp. In 2003, the Provincial Library Center settled in the castle, together with administrative services. In 2011, a "library of Flemish classics" was opened within the Provincial Library Center. Works by classical Flemish writers are collected and loaned out here. In 2014, the Antwerp provincial council decided to restructure the culture department. The library center would be merged with the Cultural Dissemination and Arts Service into a new Libraries and Arts Service. In 2015, the Provincial Library Center moved to Antwerp, but the collection of Flemish classics remained in the Vrieselhof.

Historical interpretation: The anti-tank ditch is a 33 km long defensive ditch northeast of Antwerp, between the Scheldt and the Albert Canal. The canal was constructed between 1938 and 1940 as part of the Antwerp fortress. In the 1930s, the Belgian army reoriented the fortress into a defense for infantry (support points) and machine gun companies. The military added the anti-tank ditch and bunker lines (KW line) to the existing defense by forts and redoubts. The aim was to stop tanks. That is why the anti-tank ditch had to have a slope, depth and width that a tank of that time could not exceed: a bottom of at least six meters width a width of 18m at the water surface a depth of at least three meters a minimum water level of two meters slopes of 45° Originally, the Antitankgracht was going to be a dry canal, but because it filled up with water, it was forced to be converted into a wet canal. The route had to bridge a height difference of approximately 3 to 18.5 m (DTM). That is why it was divided into about 45 sections with locks. A slide in the lock regulated the water flow and thus maintained the level. The water came partly from seepage water or local streams and partly from the Maas, supplied via the Dessel-Schoten canal. Because control over water levels was so important, each lock was defended by a bunker. The bunkers at the Antitankgracht consist of lock bunkers with flanking daughter bunkers and flanking bunkers. The lock bunkers are elongated free-standing bunkers with a large blank wall, camouflaged by 'eggs' and were usually equipped for two machine guns.

The Antitankgracht was constructed just before the Second World War to stop German tanks. Fortunately, that is no longer necessary today, but it does provide us with a nice location to cycle through.

In the valley of the Groot Schijn, where Antwerp ends and the Kempen begin, lies the impressively quiet Vrieselhof castle domain. The silence is almost palpable. Due to a variety of biotopes, it gets a different look every season. More info at https://www.provincieantwerpen.be/aanbod/dvt/vrieselhof.html
