My wife and I floated down the Boise River this past August. The scenery was amazing, the people were friendly, and it was a great time!! more »
My wife and I took to the waters on a hot August day. We rented an inflatable kayak and floated the river. It was an enjoyable float. If you rent a kayak, make sure you know how to maneuver the boat..... more »
I love fishing and crawdad hunting in this river. It's awesome.
This is a lovely, naturally occurring stream of water running in a channel at the surface of the earth. I did not confirm this visually, but I was given to know this water continues to course in a similar fashion for some distance before giving itself wholly into another large stream.
