>>1945014the forests in Twente and Friesland are also good, not as much tourists. But the biggest problem is finding a good spot if you are looking to relax during the day. Every forest has "squares" of forest so the paths are always near.
Look on google maps for forests with weirder "plots" to find a good secluded spot.
I have slept in a lot of dutch forests for a night, have been caught once. (didnt get a fine, just warning)
