Pétrusse Valley Park

Overview

Petrusse Valley Park is a lush river-valley green space that runs below the old town and beneath the Adolphe Bridge. Once part of the fortress moat system, the reclaimed gorge is now a peaceful walking trail lined with mature trees.

Highlights

• Under the Adolphe Bridge: A dramatic vantage point looking up through the double arches.
• Waterfall & Stream: A small cascade near the Viaduct, especially picturesque after rain.
• Shaded Paths: Cool walking trails on hot summer days.

History

The valley was cleared of military installations after the 1867 treaty and landscaped into a public park by the 1870s. Ongoing restoration keeps invasive species in check and maintains footbridges.

Visitor Tips

• Tip 1: Enter near the Petrusse Express elevator for an easy descent.
• Tip 2: The trail connects to the Grund - combine for a riverside half-day walk.
• Duration: 30-45 minutes.
