Hello ish, we will be glad to welcome you and your mates in Greece.
There is no forbiddance (yet) in Greece regarding the lanes, you can go almost anywhere you please, with the exception of some National Forests.
If it is possible, tell us which will be your entry point in Greece, and more or less the places you want to visit, so that we will be able to give you more information:
For instance, the whole of mount Pindos is interesting for off-road excursions and events at the NorthWest, and there are also great sites in Eastern Macedonia and Evros, as you might know, regarding the Northern Greece.
Generally, depending on the weather of course, summer in Greece is rather dry, so you won’t frequently have the opportunity to play in mud, unless you move in high altitude, seeking for springs and water. That goes for the Northern Greece (I live in Thessaloniki), and I imagine for the Southern also, but let’s here some more information from other friends too.
