Emerging from the forest of oak and rowan trees into bright sunshine, two horse-drawn carriages cross the old stone bridge and begin the climb towards the magical Bentrowan Tree Castle. Out of the window of the first carriage, a young girl with a puppy on her knee turns her head towards the loch below and sees the setting sun shining through the rainbow mist rising from the surface."Look, Mollie, there's Granny MacCardigan's cottage. I will introduce you to her very soon and we can explore the loch shore with her," says Annabel.
