カストリカムの天然記念物・トップ20

上の砂丘は、繁殖地のため、3月1日から7月まで完全に閉鎖されています。 完全に迂回するか、場合によっては道路を通るしかありません！ Komootが常に閉鎖された道に誘導し、代替案を提案しないのはイライラします！ 道が1.2km右にあるというアナウンスは役に立ちません！

Beautiful area for cycling, but you will need a dune map.

beautiful landscape

Incredibly great cycle paths and a fantastically beautiful landscape 🍀🌻

Beautiful area for cycling, even in winter

The water that is pumped into the dunes at De Kwal comes from the IJsselmeer. The water is pumped from the IJsselmeer at Andijk, purified, and transported to Heemskerk via a 52 km long pipe. There it is filtered again and is allowed to enter the dunes at 'de kwal'. There the water slowly seeps into the soil and is naturally freed of bacteria and viruses. After at least 30 days, the clean water is pumped up from a depth of 40 metres, freed of iron and lime and the drinking water is suitable for consumption. 800 litres per second Every second, the daily consumption of 6 people flows out of 'de kwal'. That is approximately 800 litres of water per second (2850 m3 per hour). On an annual basis, this amounts to 25,000,000,000 litres of water.

Be sure to drive through the dunes, there is always a different view, sometimes with fantastic flowering heather, then again with lots of temporary water holes, fantastic!

Picturesque landscape, there is a lot to discover on, in and next to the water.
