To get to or from Vlaardingen you can use the metro. They just finished the subway station last year. For traveling you will need to buy somekind of ticket. There are a few choices.
If you have to travel regular you could by a week, month or year membership for a set amount of zones. When you are just visiting once or just a few times over a period of time you could better by "Strippencards".
These come in different sizes depening or where you by them. But in general you can say the larger the amount of strips the more economical they are. Sizes ranges from 2 to 45 strips.
WHAT CAN I DO WITH A STRIP
Rotterdam is divided in 11 zones, for every zone you need to travel you will need 1 strip.
After you found out the amount of zones you have to travel through (displayed on maps around the station) you have to stamp your card. You'll have to remind if you need to travel through 3 zones you'll have to stamp the fourth strip. (3 zones will get you from Vlaardingen to Rotterdam).
When you stamp your card there's also a time stamped on your card. Your allowed to travel through the zones you payed for, for a limited time only.
2 to 4 strips 1 hour
5 to 7 strips 1,5 hours
8 to 10 strips 2 hours
11 to 16 strips 3 hours
17 to 20 strips 3,5 hours
You can travel on all forms of public transportation with a strippencard around Rotterdam. This can be a great advantage when you compare it to a train ticket which is only valid on the train.
There are special pink strippencards for childeren aged 4 to 11 and peoples carrying a 65+ senior citizen pass. These card have a reduced fair.
Trains are just one way to get in or out of Vlaardingen, there are three train station. Vlaardingen East (the night time picture), Vlaardingen centrum (the top picture) and Vlaardingen West. The trains can get you in Rotterdam Centrum in about 14 minutes and if you'd like to go to the beach at Hoek of Holland it will take you about 20 minutes trains leave very regulary mostly between 2 to 6 times in a hour depending on what day an time you travel...
