With regards to the Netherlands in particular, we had been warned that it was tough to find decent free camping spots, and that paid camping is expensive. And while both of those things are true to a certain extent, we haven't found it that difficult. In fact, we've been here for over three weeks and have only spent €42 ($62 CAD, $50 USD) on four paid nights. The rest have all been free.
So, how do we do it?
