A short but pleasant 250m elevated boardwalk hidden in the woods just east of Lake Malta near the New Zoo. We wouldn't exactly call it 'in the treetops' - there aren't any special views or anything. If anything it saves your legs from going up and down the steep ravine 13m below at its deepest point. Finding it can be a bit tricky, which adds to the allure - look for a metal gate with a sign for “Kładka wśród drzew” at the back of the zoo parking lot, or follow a path from the intersection of ul. Krańcowa and ul. Wiatrakowa. In the warm months there is even a small chill-out zone at one end of the walk, featuring a coffee cart and some hammocks. Keep an eye out for local avian friends like woodpeckers, blackbirds, tits, jays, golden orioles, and goldcrests.
