The Amsterdamse Waterleidingduinen is a beautiful nature reserve in the province of North Holland in the Netherlands. It is a dune area with lots of water channels. It has the largest population of fallow deers in the Netherlands. It is estimated that there are 3000 fallow deers. There also foxes, some of them are used to people, roe deers and many birds. We also visted the neighboring Zuid-Kennemerland National Park. We were not able to spot the wisents (European bison) which were released in the Kraansvlak area in 2007. We saw a nice herd of Highland cattle.
