The International Peace Garden is a 2,339-acre botanical garden commemorating peace between the United States and Canada along the world's longest unfortified border. More than 150,000 flowers bloom within the formal garden, which features an 18-foot floral clock. One of the site's highlights is the Peace Chapel, the only building to straddle the international border. A scenic loop drive takes visitors by lakes, fountains, wildlife, picnic areas and campgrounds. The property is also home to the International Music Camp, one of the leading fine arts summer schools in the US and Canada. Open daily, 24 hours.
