The purple route runs around De Putten, a vast meadow area with ditches and ponds, managed by Natuurmonumenten. The name comes from the clay pits that were dug for clay extraction in Castricum.
This route along centuries-old church paths through the Eilandspolder starts in De Rijp. In the Golden Age, this was a prosperous village thanks to herring fishing, whaling, trade, and shipbuilding. It is still one of the most beautiful villages in North Holland.
Afterwards, you walk into the polder, where chirping meadow birds break the silence. The Eilandspolder is a paradise for nature lovers. Discover it for yourself with this brisk walk of approximately thirteen kilometers.
During the breeding season from March 15 to June 15, parts of the route are inaccessible.
