In reply to Enty:
camping les prez in Grez-sur-loing is very good, cheaper than musardiere and closer to baker,village ameneties + canoeing + campsite pool on door step for days off.
it is more south though, 30 mins drive to trois pinions carpark, 15 elephant, 15 diplodicus, but good if you want to avoid the crowds or easy access to a6(and/n6) if you want to get up to crags near barbizon etc.
p.s. the coissants are also better with sort of feathered crispy ends 😃
