Campsite near Amsterdam

Siberdragon

We are motorhomers and try not to take the van off site once pitched.  We plan to visit Amsterdam in May and would like to have a site that has easy access to Amsterdam either via train or if on the city's outskirts by tram.  The site I initially considered
was at Amsterdamse Bos but I have been told that this is very close to Schipol, does anyone have a recommendation for a site that is not near Schipol please.
