Winding past monuments, towers, ruins, a beer garden and an enormous Thingstätte (amphitheatre; built by the Nazis in 1935), the 2.5km-long Philosophers’ Walk has captivating views of Heidelberg's Schloss, especially at sunset when the city is bathed in a reddish glow. Access is easiest via the steep Schlangenweg from Alte Brücke . Don't attempt to drive up as the road is narrow and there's nowhere to turn around up the top.
