We used a Groupon to take an eagle viewing float trip. We had a good enough time, though, as Washington hikers and climbers, we really weren't the typical tourists that would normally book this kind of a day. Floating a river is kind of an inert "activity."
Our guide was enjoyable enough. I can't give the tour a lot of stars because we saw and heard nothing of the"hot lunch" we were promised. Reading other reviews, I'm not really surprised by that.
I wouldn't find this very enjoyable on a rainy day. Fortunately, ours was sunny.
