Safe parking ideas
 

Two of us are heading for the Pyrenees on Monday for a month of fun.
Two men, two trail bikes and two dual purpose bikes. Once we arrive we shall have 2 bikes and a van to stash somewhere.
Any one done similar and know of safe parking, friendly landowner, motorcyclist, etc.? Anywhere Pyrenees ish, France or Spain, North or South or even Andorra, for a couple of weeks or so. Any thoughts?
