The Garden is a living museum, dedicated to the advancement and appreciation of gardening, horticulture and conservation. They have several specialty gardens, host year-round events, tours, and allow self-guides too. There really is something fun for kids and adults!
It isn’t free to get in but it’s not expensive and your admission goes to a good cause.
The garden is right next to the Old Idaho Penitentiary so it may be worth visiting both at the same time. It is also very close to the Warm Springs Golf Course if you want to try and sneak in a round before or after you’ve enjoyed the scenery here.
