Lons-le-Saunier

Lons-le-Saunier, the capital of the Jura department in eastern France, is a charming spa town nestled between the Jura mountains and the wine-producing plains. Known for its salt springs (hence the name), it offers a blend of thermal relaxation, rich history, and stunning natural surroundings. The town is also the birthplace of the famous French chemist Louis Pasteur, and its streets are dotted with elegant 18th-century architecture.

Highlights & What to See

• Thermal Baths – Soak in the mineral-rich waters at the Grands Thermes, a historic spa complex that has been drawing visitors since Roman times.
• Maison de Louis Pasteur – Visit the birthplace and childhood home of Louis Pasteur, now a museum dedicated to his life and scientific achievements.
• Arcades de Lons – Stroll under the covered arcades of the main shopping street, rue du Commerce, lined with boutiques and cafés.
• Parc des Bains – Relax in this lovely park with a lake, walking paths, and a bandstand, perfect for a picnic.
• Musée des Beaux-Arts – Explore a collection of fine arts and local history housed in a former bishop's palace.

Suggested Time to Spend

Two to three days allows you to enjoy the spa facilities, explore the historic center, and take a day trip into the nearby Jura mountains for hiking or wine tasting. If you're short on time, a full day can cover the main sights, but you'll miss the relaxed pace of the thermal experience.
