Hi Alan, sorry, only just noticed your post. When we did this last year there were only 2 sightly more "challenging" lanes - one had overhanging branches that we had to push through (will try to remember loppers this year) and the other was a deep ford with some rocks under the water. The first can be avoided by using a single track road that runs almost parallel to it, the second one needed a U-turn and a longer round trip to avoid the ford.
If it helps, I did the first one, but avoided the second. All the others are either forest track equivalent, or overgrown (grass / moss) potholed single track roads.
hope that helps, Alan
