Aetsveld Route

Back to Hiking

A walk from the fortified city of Weesp, along the winding river Vecht, through the beautiful Aetsveldsche Polder. The fortified city of Weesp and Muiden were important parts of the north-east side of the Stelling van Amsterdam. The walk will successively take you past Fort Uitermeer and Fort Hinderdam. Around Fort Uitermeer is a footpath. In the renovated and partly in the former glory restored towerfort Uitermeer you will find a restaurant. You can reach the small island where Fort Hinderdam is located via a narrow causeway. This Fort is not open for the public. Weesp has for centuries been an important fortress. The walkway through the Aetsveldsche Polder rund along the riverbanks of an old Vechtstream. In this vicinity there there have been findings of habitation dating back to the third century BC. A nice walk, partly on paved roads (along the Vecht), and partly on grass paths.
