The home of the 1972 Olympic games, Olympiapark’s Olympic Stadium is available for tours and special adventure fun. Climb the expedition roof of the stadium, zip-line across the field, ascend from the rooftop to the stadium floor, or simply take a tour of the stadium. Surrounding the stadium is a free public park for guests to enjoy. Tidbit: The rolling hills of the park are actually “rubble hills.” Following the destruction of many Nazi buildings after World War II, piles of rubble were placed here. Today, they are beautiful, green hills surrounded by trees and a man-made pond.
