Do we have a door that leads to a forest?
Yes. Go straight out the main door of the Castle, through the courtyard, though the gate and across the drawbridge. Ignore any activity in the moat and continue straight ahead until you are among the trees we brought with us.
Notice that the newer growth of the last few years has a different orientation as to what constitutes "up". It's subtle, but observable, particularly in the fore-and-aft direction.
