Public transport, The Hague
Trains between The Hague and Amsterdam, Schiphol or Utrecht run often and until about midnight. There is also a nighttrain connecting the big cities that goes once an hour.
The center can easily be explored by foot. For further distances, trams and buses are good in The Hague.
The Hague has two main train stations Centraal (CS) and Holland Spoor (HS).
From here trains connect to almost anywhere in europe.
The tram system is very widespread and punctual in The Hague. It's the best way to get around.
I took the train to Den Haag Centraal and it was not fun! I started out in Hoofddorp at 9am and didn't arrive in the Hague until almost 12 noon because of problems with the trains that day. There were a couple of accidents and some lines were down on the tracks causing chaos and frustrated commuters everywhere. Needless to say I ended up with less hours than I had planned to spend in the city.
I walked everywhere. A lot of the major sights are very close to each other so this was the cheapest way to see the city ;)
I travelled to The Hague by train from Amsterdam Centraal Station. The trains are frequent having a direct service to CS Station evey 30 minutes. The trains are are also quite comfertable too :-)
While in The Hague I just used my legs to walk about. There is a tram system but it is a lot more fun just to walk about and discover everything.
Getting to Den Haag was pretty easy, we left out of Amsterdam from central station. I dont rememeber what the cost was but it should be around 8 euros, and about 2 1/2 hours on the train maybe a little less.
One of the best and comfortable ways to visit The Hague is by train. The Hague has two importan traint station. The Hague Central and The Hague Hollands Spoor.
Den Haag is about 45 minutes from Amsterdam by train. There are frequent trains to and from Amsterdam, as well as to many other Dutch towns.
