Schlangenweg (Snake Path), Heidelberg

Known as the Snake Path due to its many winding switchbacks, this footpath connects the Old Bridge with the Philosophers' Path. Stretching nearly 500 meters and climbing about 90 meters in elevation, it is largely carved into the hillside, with several switchbacks flanked by red sandstone walls. Locate the entrance to the Snake Path along the upper western section of the Philosophers' Path, then step through the arched portal to begin your descent.

Originally a vineyard trail, the path led to vineyards on the south-facing slope above the Neckar. These belonged to the village of Neuenheim, which was incorporated into Heidelberg in 1891. Today, the area is home to gardens and developed properties.

The Snake Path was renovated in 1788, when steps were added. Carefully make your way down the steep cobblestone steps, stopping at the stone lookout balconies built into the bends to take in views of Heidelberg Castle rising above the Old Town.

The numerous dry-stone walls along the path provide a valuable habitat for heat-loving species such as the wall lizard. You can also spot medlar trees, a once-common fruit tree species that has become increasingly rare.
