Ponds 'Begijnenvijvers'

The ponds were once dug by order of the nuns of the Agneten Convent in Peer. The ponds are a paradise for fishermen. In the adjoining forest area Resterheide hikers can choose from different routes through the valley of the Bolliserbeek.
In one of the ponds lives, it seems, a monster, the monster 'Wazdeddo', can you find it?
