I walked through this tunnel today. I had to bend over to stop my head hitting the top. My two companions were not brave enough to walk through. Later, they found a smallish zip wire. They both went on the zip wire and cajoled me into going on it. My stomach flipped as I careered down the wire only for my husband to drag me back to the top and then let me go down again! It was a great photo opportunity for all but luckily for me, the images will not be featuring on this blog!
