You used to have to get reservations to visit the Japanese Friendship Garden but now, it's no reservation required. I think they've done a nice job with it.

The Japanese Friendship Garden is located on a rocky island in the Snake River in the heart of Idaho Falls. The island is historically important as the site of the first bridge to span the Snake River in Eastern Idaho. The garden was developed to celebrate thirty years of associating with our Japanese sister city, Tokai-Mura, and to encourage friendship with peoples throughout the world.

The Japanese Friendship Garden contains a traditional Japanese garden gate, many water features, a viewing platform, a deck, a "Dragon’s Path" across a pond and the large Japanese lantern given to the city by Tokai-Mura. The many features have been built by volunteers who have donated many, many, many hours of their time to these projects and maintaining the garden.
