Le Plan de Phazy

## Overview Le Plan de Phazy is a naturally carbonated mineral spring located in the commune of Risoul in the Hautes-Alpes department of southeastern France, near the small hamlet of Le Plan de Phazy along the Durance River valley. Situated at an elevation of approximately 1,000 meters in the heart of the French Alps, this spring has been known for centuries for its distinctive sparkling, iron-rich waters that bubble up from deep geological formations. The spring at Le Plan de Phazy is one of the rare naturally gaseous (carbonated) cold mineral springs in the region. Historically, the waters have been valued for their mineral content — particularly iron and carbon dioxide — and the site has long attracted visitors seeking its reputed therapeutic properties. The reddish-orange mineral deposits around the spring's outlet are a telltale sign of its high iron content. Local tradition holds that the spring has been used as a drinking water source for generations, and it remains a popular stop for hikers, cyclists, and travelers passing through the Durance valley. The GPS coordinates place the spring at 44.6581°N, 6.6038°E, along the road between Guillestre and Mont-Dauphin in the Hautes-Alpes. The surrounding landscape is quintessentially Alpine — dramatic mountain scenery, pine forests, and the rushing waters of the nearby Durance River. ## Directions 1.

Visitors are encouraged to confirm the route using a GPS device or mapping application.* ## What to Expect At Le Plan de Phazy, visitors will find a natural mineral spring that produces naturally carbonated water with a distinctive fizzy quality. The water emerges cold and effervescent, and the surrounding rocks and basin are often stained a vivid orange-red from iron oxide deposits — a striking visual feature that makes the spring easy to identify. The spring is publicly accessible and has historically been used as a drinking water source by locals and travelers. Visitors have reported that the water has a mildly metallic, mineral taste characteristic of iron-rich carbonated springs. As with any natural water source, conditions can vary, and the water quality is not officially guaranteed. The setting is scenic and peaceful, nestled in the Alpine valley with views of the surrounding peaks. The area is close to notable attractions including the historic fortified town of **Mont-Dauphin** (a UNESCO World Heritage Site designed by Vauban) and the ski resort of **Risoul**. The spring makes an excellent stop for those touring the Hautes-Alpes region, whether in summer or winter. The site is accessible year-round, though winter conditions may make the approach roads icy. The spring itself typically flows continuously regardless of season.
