i live in the area, not done as much greenlaning as i'd like( always at work, earning the money to keep the disco running ) but i can recommend the lane that goes from Ickenthwaite to Nibthwaite, i've done that a few times, a mate of mine was up there the other day on his trials bike and he said the water was almost up the spark plug, its not a ford just big puddles, i've never seen them that deep myself
