Fontaine-de-Vaucluse

Fontaine-de-Vaucluse sits at the end of a gorge carved by one of the most powerful springs in the world. The village — about 650 inhabitants — is where the Sorgue river begins, erupting from a cliff-face shaft that descends 308 metres into the Provençal limestone. For much of the year the spring sits below its own rim, a deep still pool of blue-green water that gives nothing away. In winter, after rain or the snowmelt of Mont Ventoux, it turns: the water rises, breaks over the cliff edge, and the Sorgue swells to a torrent audible from the village square.

The place has attracted obsessives across seven centuries: the poet Petrarch, who spent sixteen years here writing the Canzoniere; Jacques Cousteau, who almost died trying to find its bottom; a German cave diver who descended at night without a permit; and a Resistance poet who organised parachute drops in the hills above. The spring itself resisted all of them. Its floor was finally reached not by a human but by a robot, in 1985.

A Closed Valley

The Latin name Vallis Clausa — closed valley — described the geography exactly: a gorge sealed at one end by a cliff, from which water appeared without apparent source. The village grew up around this anomaly. In the 6th century, the bishop of Cavaillon, Saint Véran, is said to have driven a dragon called the Coulobre from the Sorgue — the earliest written record of the spring's place in human imagination, preserved by Gregory of Tours.

Petrarch, 1337–1353

In 1337, the Italian poet Francesco Petrarch settled here at the invitation of his friend Philippe de Cabassoles, Bishop of Cavaillon, whose fortified castle — built around 1030 — commanded the valley from the cliff above. Petrarch built a garden on the Sorgue's banks, amassed a library of remarkable scope, and produced foundational texts of the Italian Renaissance: the Africa, the De vita solitaria, the Secretum. He also continued the Canzoniere, his 366 sonnets addressed to Laura de Noves, a noblewoman he had first seen in an Avignon church on April 6, 1327. She died, as he recorded in a manuscript note, on April 6, 1348 — exactly 21 years later. He left Fontaine-de-Vaucluse in 1353 and never returned to Provence.

Paper and Industry

The Sorgue's extraordinary flow made the valley commercially vital. The first paper mill — the Moulin du Martinet — opened in 1522. By the 18th century, eleven mills employing five hundred people lined the banks, producing paper powered by the same spring that had inspired Petrarch's sonnets. Silk, wool and dye works operated alongside them. The industry declined through the 19th and 20th centuries; the valley quieted. In 1973, the last surviving mill was revived as the Vallis Clausa — a working paper mill using 15th-century rag techniques.

Exploration and the Depth Question

The first documented descent was in 1879, when Nello Ottonelli reached 23 metres in heavy diving equipment. Jacques Cousteau dived in 1946 (reaching 46 metres, nearly dying from carbon-monoxide-contaminated air) and again in 1955 (74 metres, the human limit on air). German cave diver Jochen Hasenmayer reached 200 metres in 1982, diving alone at night after his permit was refused. Robots finally resolved the question: the Modexa 350 touched sandy bottom in 1985 at 305 metres.

The Resistance

During the Occupation, the Sorgue valley sheltered Resistance networks. The Surrealist poet René Char, born in L'Isle-sur-la-Sorgue, led Maquis units as 'Capitaine Alexandre', coordinating arms drops while publishing nothing. His wartime manuscripts — alongside works by Picasso, Matisse and Éluard — are now in the Jean Garcin 1939–1945 History Museum, whose scenography was designed by Willy Holt, production designer of The Great Escape.

The Spring (La Fontaine)

The path to the spring follows the Sorgue upstream from the village — 800 metres through plane trees and past restaurant terraces. The pool at the end sits inside a semi-circular cliff wall; in summer it is calm and startlingly blue. In late autumn and winter, water overtops the rim and fills the gorge. The contrast between what summer visitors see and what winter visitors see is radical. Go after rain if you can.

Vallis Clausa Paper Mill

Located on the Sorgue just before the spring path. Entry is free. Workers demonstrate the full 15th-century process — rags, vat, mould, press — and visitors can make a sheet of paper. The mill also holds antique printing and lithographic equipment.

Château des Évêques (Ruins)

The 11th-century fortified summer residence of the bishops of Cavaillon sits on the cliff above the village. Access is by a steep path; the ruins are open to visit. The view over the spring and the gorge is the best available from above.

Musée-Bibliothèque François Pétrarque

Built on the site of Petrarch's house, the museum holds around 3,500 books and a collection of drawings, prints and manuscripts relating to Petrarch and Laura. The building also documents the poet René Char, whose connection to the valley continued into the 20th century. Open April–September; entry €7, reduced €4.

Musée du Monde Souterrain — Collection Norbert Casteret

A tribute to the French speleologist Norbert Casteret (1897–1987), displaying 400 cave crystallisations he collected over fifty years of exploration, set in a life-size reconstructed underground environment. Guided tours in French, approximately 40 minutes.

Jean Garcin 1939–1945 History Museum

Documents the Occupation and Resistance in Provence, with original manuscripts by René Char, Picasso, Matisse, Max Jacob and Paul Éluard. The scenography is unusually ambitious for a regional museum.

Canoe on the Sorgue

A popular 8-kilometre descent by canoe from Fontaine-de-Vaucluse to L'Isle-sur-la-Sorgue is available from rental operators in the village. The Sorgue's clarity and steady current make it one of the best canoe routes in Provence.

For the Spring at its Most Dramatic

Winter and early spring — November through April — are when the karst reservoir overcharges after rain and snowmelt and the Fontaine de Vaucluse overflows its cliff. Flow can reach 100 cubic metres per second, versus an average of 21. The valley floor floods and the sound carries. Weekdays in December or January bring very few other visitors.

For the Village Itself

May and early June offer warm weather, the spring still carrying some winter flow, and manageable visitor numbers. September has the same virtues at the other end of summer.

What to Avoid

July and August: the village's permanent population of 650 is supplemented by dense summer tourism. The path to the spring becomes crowded and lined with souvenir stalls. The spring itself is at its most quiet and least dramatic in high summer — a still pool rather than a torrent.

Markets

Thursday mornings: Fontaine-de-Vaucluse hosts a small market on the village square.

Getting There

Fontaine-de-Vaucluse is 30 kilometres east of Avignon and 7 kilometres east of L'Isle-sur-la-Sorgue. By car: take the D25 from L'Isle-sur-la-Sorgue (10 minutes). There is no direct train; the nearest station is L'Isle-sur-la-Sorgue on the TER line from Avignon. From there, a taxi takes about 10 minutes. A regional bus (Zou! network) runs from Avignon to Fontaine-de-Vaucluse several times per week, journey approximately 45 minutes — check schedules in advance as frequency is limited.

Parking

Paid parking throughout the village and on the approach roads. Budget approximately €4 for 2 hours. Parking fills quickly on summer weekends; arrive before 10am or after 3pm. Several car parks are signed on the D25 before the village centre.
