I was able to find info and drove to Treehouse Island.
The owner, Grady, took us by boat across Silver Lake to the Island. We then zipped 5 lines through beautiful trees. We climbed a lot of ladders, but we were always hooked in so even a misstep on the ladder we would not have fallen.
My guide, along with Grady was Chi!
A very beautiful place and a nice day ziplining.
There were views of Mt St Helens as we were going across the lake. I couldn't see the top because of clouds, but we had a blue sky and nice temps for being out and about!
