Go climb a tree

This treetop trail in Germany's Bavarian Forest National Park is one of the world's longest canopy trails—and one of the most unique. Visitors to the egg-shaped trail can wind their way around the trees for almost a mile, reaching heights of 144 feet all while getting breathtaking views of firs, beeches, spruces, and more. Not only do canopy walkways like this one give visitors a bird's-eye view of the surrounding forests, they also allow people to experience nature without harming it.
