The lush 63-acre University of Idaho Arboretum and Botanical Gardens, in Moscow, is a jewel of the Palouse. We spent about two hours walking on just one of the many trails that wind through the willows, conifers, lilacs, roses, poplars, and hundreds of other trees, shrubs and flowers that are organized into different geographical groupings. We also saw turtles, tadpoles, and birds of all kinds. It's a great place to spend an afternoon with the kids. And it's free!
