Most people who travel to The Netherlands only go to Amsterdam. However, if you truly want to discover the full extent of Dutch Culture you should look further afield. Each of the smaller cities have their own charms and the Dutch countryside is among the least explored in Europe.
Besides Amsterdam, there is many more cities that have their own unique experience. Most cities/places are easy to reach by public transport within one hour. Perfect for day trips!
The Netherlands is not famous for its nature. Pretty logical for a country with 18 million inhabitants in such a small country. But if you are looking for a breath of fresh air or a small hike, there is some pretty nice places to go to.
