Sougraigne: Salt Spring, Hiking Trails and History

When planning your trip to Sougraigne, the source of the Sals, the Domaine de l’Eau Salée and trails connected with the area’s history all play a special role. You can choose between exploring independently, joining a guided hike and taking a guided tour by reservation. Each option has a different focus: with one, you use a map and trail markers to plan your own route; with another, the emphasis is on the history of salt or a tour with a set duration.

Salt Spring and Landscape

At its source, the Sals Spring contains up to 60 grams of sodium chloride per litre—about twice as much as seawater. This concentration makes it a geological curiosity. You can discover the spring on a hike from Sougraigne, for example, combining the landscape with a specific aspect of the area.

The Domaine de l’Eau Salée covers 600 hectares and is managed by the Office National des Forêts. It overlooks the Sals Valley. Visitors interested in the area will therefore encounter not only the spring, but also an extensive, wooded estate with a strong connection to the valley.

Traces of Salt History

The Domaine de l’Eau Salée was built shortly after the mid-17th century. The ruins of the Métairie de la Fontaine Salée and the former barracks of the Gabelous have been preserved there. These named ruins provide tangible points of reference for the area’s history; they sit alongside the grounds’ current use by hikers and visitors.

The annual Marche du Sel also explores the past. The Association Salicorne organises the guided hike, following in the footsteps of former salt smugglers. During the event, the salt spring at Sougraigne is reached with pack donkeys, and salt-making is demonstrated on site using fire and cauldrons. If you are interested in this event, check the dates before your trip.

Explore the Trails Independently

The “Entre sel et verre” discovery trail runs through the heart of the Domaine de l’Eau Salée forest. It is a circular route that passes information panels, each explaining a chapter in the region’s history. The route also has explanatory signs and picnic areas. The walk therefore combines time in the forest with historical insights and a place to take a break.

The route is considered accessible for people with intellectual disabilities and people with hearing impairments. Check locally whether the conditions meet your personal needs. A permanent orienteering course offers another option: use a map and wooden markers to find your way independently and discover the area’s history at your own pace.

The orienteering map is at a scale of 1:5,000 and is available from the Rennes-les-Bains Tourist Office. Check how it is issued before your trip. This lets you plan how to obtain the map separately from deciding whether you would prefer the themed circular trail or the self-guided orienteering course.

Guided Tour and Practical Planning

The guided tour of the Sals Spring and the glass furnaces lasts about two and a half hours and requires a reservation. It is offered year-round in 2026; arrange a date before your trip. Unlike the trails, where you find your way independently, the tour provides a set timeframe for your visit.

The restored former Verrerie is an open space available to hikers. If you are considering staying overnight there, check the conditions in advance. This practical question can be considered separately from whether you plan to spend your time hiking, visiting the information panels on “Entre sel et verre” or taking a tour by reservation.

When looking for a hotel in Sougraigne, you could start by asking yourself which of these activities you want to shape your stay: exploring independently, learning about the history of the salt trade or taking a guided tour. The differences between the circular trail, orienteering course and reservation-based tour offer specific points to consider, without requiring you to assume that a particular accommodation has certain amenities.
