The capitol of the Netherlands is Amsterdam. Amsterdam is pretty notorious for its liberal approach on drugs and prostitution. It also holds famous museums and historic architecture.The language they speak is mostly dutch. It was odd to find that the majority of the population was not religious. The entire country is pretty flat.
If you're deciding to stop in Friesland or Groningen then you better go waddling. Waddling is where you walk on the bottom of the sea!! At low tide of course. It's mostly done north of the Holland. This can also be done in Germany or Denmark.
Stop by Zeeland to see the Delta Works. This is a floodgate that prevents floods during large storms. It was built in early February 1953 after a severe storm flooded costal areas, killing around 1,800 people.
