Silverwood: worth the drive
My children and I took an 8 hour drive to get to Couer D'Alene and planned on spending two days at Silverwood (just north in Athol). Had I know how enjoyable it would be, I would have extended our visit. Boulder Beach was fantastic! There is something for everyone, even if all you want to do is lay around in a lounge chair for eight hours. The staff was very courteous and friendly. As for the "theme" part of the park, that was wonderful as well. Again, lots of friendly employees. As we were there during the week, the lines for rides was minimal. A must is the train ride around the park. It gives you a good overview of the park as well as the history. I only had one complaint, and that was there wasn't quite enough shade in Boulder Beach...but then again, the sun is what you are there for! :)
We will definitely return next summer for another visit.
