Blue Mountain - Three Sisters and top of the Giants Stairway
The giants stairway starts beside the three sisters then goes all the way down in to the valley. It's a lot of steps and very steep. All of it is on the side of a cliff. In some places the stairs are metal grate over air.
While we were at the three sisters our guide told us "you can walk to the first of the sisters but don't walk down the giant's stairway."
So I (Tyler) did.
I made it down about half way before I had to start booting it back to the bus before it left. Note to self: down is easy. Up isn't.
It was totally worth it.
