Aarhus Botanical Garden (Botanisk Have) was founded in 1875 and covers an impressive 53 acres. Highlights are the large hothouses with subtropical plants from around the world, recently renovated with the addition of a large tropical dome.
The gardens are home to a variety of fun summer programs for kids, as well as concerts and shows in the on-site amphitheater. It's also a pleasant place for a stroll or a picnic, with numerous paths, two small lakes, and plenty of open green space.
