Kruidvat reminds me of a Dutch version of CVS or Walgreens. They have a little bit of everything, from makeup and hair items to baby products and items to clean your house. They are also one of the stores that sells discounted train tickets from time to time.
The closest Kruidvat is located in Sittard, relatively close to the ABC parking lot. There are also stores located around Heerlen. If you want to search for other stores, go to their website and use the search function. Change the radio button above the search bar to “Winkel”, which is the Dutch word for a shop. Be sure to use Dutch city names or postcodes when searching.
