Through a large pond in the De Wijers nature reserve in Limburg, Belgium, runs a cycling lane that goes right through the waters instead of going over it. The 212-meter concrete path was built below the water level and dips low enough to put riders at eye level with the water. Two five-feet high embankments on either side of the bike path keeps the water of the pond away, while underground tunnels under the bike path ensures that amphibians and other aquatic life in the pond could freely move between the two sections.
Since its opening in 2016, “Cycling Through Water” has proved to be a hit with tourists and locals. Hundreds of thousands of them have cycled through the sunken path.
