La Sône: Tufa Springs, Garden and History

Discover La Sône through three themes: the Jardin des Fontaines Pétrifiantes, the history of the town and the landscape along the Isère. Geology and plant life shape the garden, while the Tour de La Sône offers a tangible link to the past. The Sentier du Martin-Pêcheur combines birdwatching with information about the river; the La Belle Via cycle route makes La Sône a possible stop along the way. If you’re looking for a hotel for your stay, you can choose your focus based on whether the garden and tufa, local history or activities along the Isère will shape your trip.

Geology and Plant Life at the Jardin des Fontaines Pétrifiantes

The Jardin des Fontaines Pétrifiantes brings geology and plant life together. Springs below La Sône form tufa, a light, porous rock that develops when mosses and plants become coated in lime. This phenomenon can be observed in the garden. The garden is home to more than 800 plant species, including rare exotic, Mediterranean, aquatic and tropical plants. If you’d like to explore botanical diversity as well as tufa, you can find both in one place. The garden received the French “Jardin remarquable” label on December 22, 2017; this is a permanent national heritage designation. The distinction adds a cultural dimension to its connection with nature.

Local History at the Tour de La Sône

The Tour de La Sône is a fortified 12th-century building that now houses two exhibition rooms featuring objects relating to the town’s history. Here, historic architecture and local history come together. Unlike the garden, this part of a visit shifts the focus from plants and tufa to exhibition objects and the history of the area.

Birdwatching and Activities Along the Isère

You can watch birds along the Sentier du Martin-Pêcheur; three information panels explain the river’s natural environment. The trail runs alongside a section of the Isère rich in biodiversity. La Sône is also a possible stop on the La Belle Via cycle route along the Isère. The Sentier highlights birdwatching and information about the river, while La Sône offers a potential stop for cyclists. Check current route conditions before setting off. Canoeing and kayaking are also offered on calm stretches of the Isère, accompanied by the Club Aviron Sud Grésivaudan. These activities are suitable for beginners and experienced participants alike.

A Traditional Festival for Your Itinerary

The Fête de la Truitelle Sônoise is a traditional village festival. The local council confirms the date and program each year. If you’d like to plan your stay around the festival, check both before setting your travel dates.
