Pont Du Gard

The entire aqueduct that the Pont du Gard is part of descends just 17 metres across its 50-kilometre length. That is a gradient of 0.034 percent: a fall of roughly 34 centimetres per kilometre, with some sections dropping as little as 7 millimetres per 100 metres. Roman engineers in the first century AD, working without GPS or laser levelling, held that precision across half a century of construction through varied terrain. The Pont du Gard is the most spectacular visible section of a system that supplied 40,000 cubic metres of water daily to the city of Nimes, but the engineering achievement at the bridge is arguably less impressive than maintaining that gradient through 35 kilometres of underground conduit that preceded it.

The aqueduct was built around 50 AD to carry water from a spring near Uzes to Nimes, a distance of 50 kilometres. It ceased functioning around the 6th century when the maintenance infrastructure of the Roman administration collapsed. The bridge itself survived because it was too useful as a river crossing to demolish; medieval stonemasons chiselled away at the lower tier to make carts fit, and a separate road bridge was added alongside in the 18th century. The damage from those centuries of improvised use is visible today in the mismatched stonework on the lower arch level.

The structure

Three tiers of arches rise to 47 metres above the Gardon River. The lowest tier has 6 arches, the middle tier 11 arches, and the top tier 35 smaller arches that carried the water channel itself. The entire structure is built from limestone extracted from quarries near the site, assembled without mortar, and held together purely by weight and precise cutting. Each stone was numbered to indicate its position; the numbers are still visible on some blocks. Around 50,000 tonnes of stone were used in total, moved and placed by an estimated 1,000 workers.

Standing beneath the middle tier gives the most useful perspective on scale. The bridge that appears manageable from the riverbank becomes genuinely monumental once you are underneath it.

Entry and access

Access to the bridge walkways is free. Entry to the museum (on the right bank) costs 8 euros for adults and 6 euros for reduced-rate visitors; children under 18 enter free. The museum covers the aqueduct’s construction, the water delivery system for Nimes, and the history of the site’s post-Roman use. It is well done and not obviously skippable, particularly if you have children in the group who benefit from the visual displays.

Cultural spaces including the museum are closed from early November through the end of February. The site itself remains accessible year-round. From May 15 to September 20, the monument is illuminated every evening after dusk. From July 4 to August 30, a sound and light show runs at 10:30pm on weekday evenings. Neither the illuminations nor the show are publicised particularly aggressively, which means they are considerably less crowded than the daytime visits.

Getting there

The nearest airports are Nimes (FNI), 20 km south, and Avignon (AVN), 25 km southwest. The site is 3 km from Remoulins and accessible by car or shuttle bus from Remoulins station in summer months. There is significant parking at the site (charged separately from site admission); arrive before 10am in July and August or you will queue for parking.

Nimes and Avignon are both worth combining with a Pont du Gard visit. Nimes has the Maison Carree, a Roman temple in almost complete condition, and the amphitheatre (Arena of Nimes) that still hosts events. Uzes, 12 km north, is the medieval walled town from which the aqueduct’s water originally came; it is quieter than both Nimes and Avignon and has a very good Saturday market.

Swimming and kayaking

The Gardon River beneath the bridge is a popular swimming spot from late June through August, when the banks become informal beaches. Swimming is at your own risk under municipal decree, and the current can be stronger than it appears after rainfall. Water shoes are useful on the rocky riverbed.

Kayaking from Collias, a village 8 km upstream, is the most popular active way to approach the bridge. Multiple operators in Collias rent single and double kayaks for the 2 to 3 hour downstream paddle that ends directly beneath the Pont du Gard’s arches. Arriving at the bridge from the water and looking up at the three tiers from river level produces a better sense of the structure’s scale than the pedestrian approach. Book ahead in July and August; the Collias operators fill up by midday.

Eating nearby

The site’s own restaurant serves standard French brasserie food at outdoor prices; it is fine for convenience but not a destination in itself. For better eating, Remoulins has several small restaurants along the main street; Le Castellas in the village of Collias (the kayak departure point) has been well regarded locally for years as a proper regional table. In Uzes, the Saturday market has prepared food stalls that make an excellent late breakfast before driving to Pont du Gard for the quieter mid-morning period.

Staying in the area

Most visitors come to Pont du Gard as a day trip from Avignon, Nimes, or Montpellier. For those who want to base themselves closer, Remoulins has budget hotels and there are several chambres d’hotes in the surrounding countryside. The campsite at Pont du Gard itself runs from April to September and has a good position on the riverbank, though it books quickly for the peak July-August window.

Avignon is the strongest base for multiple-day exploration of the area: it has the Palais des Papes, good hotels across all price ranges, and access to Pont du Gard, Les Baux-de-Provence, and the Camargue within reasonable driving distance. Trains from Avignon TGV station connect to Paris Gare de Lyon in 2 hours 40 minutes, making it a practical start or end point for a southern France trip.

The most useful single piece of advice for visiting Pont du Gard: go on a weekday morning in late May or early September, before 9am if possible. The mid-tier walkway crosses the bridge at that hour in near silence. Between noon and 4pm in August, you are sharing the same walkway with thousands of other people. The structure is unchanged; the experience is not.
