Off roading ? Green laning

hello I'm very new to off roading / green laning, I had a defender 90 that I put my heart and sole in to! Not to mention all my money lol it sadly got stolen from outside my house!! And never has been seen or heard of agen the jeep itself would have been an off roaders dream but I had that much time and effort and just loved it that much didn't really do much! I went off the landys for a while and me and my mate have started a new protect on a td5 discovery but won't be ready for a while so for now we are just running an old Suzuki vitara that dose what we need it to do for now!! WE LIVE IN THE NORTH EAST .. DURHAM AND JUST LOOKING FOR SOME EASY GREEN LANES TO START OUT ON AND REALLY HOW TO GO ABOUT GOING ON THEM ? As we have never done it before and don't know much about it so any advice would be great thank you
