Visiting Collias and the Gorges du Gardon

A limestone canyon carved by the same river that runs under the Pont du Gard, a village built for it, and an eight-kilometre paddle that ends at the aqueduct itself. About fifteen minutes from Uzès.

Collias is a small village on the Gardon river, about fifteen minutes from La Valette Boutique, sitting at the mouth of the Gorges du Gardon, a twenty-nine kilometre limestone canyon with cliffs up to 150 metres high. The river here is calm and shallow enough for a family paddle, and the classic route, eight kilometres downstream from Collias, ends directly beneath the Pont du Gard. The gorge itself, recognised by UNESCO as a Biosphere Reserve since 2015, is also good walking and climbing country, home to Bonelli's eagles, Egyptian vultures and a colony of European beavers.

Fifteen minutes from home

What surprised us about the Gorges du Gardon

We expected a river paddle and a nice canyon. What we did not expect was how quiet it is once you round the first bend out of Collias: no road noise, cliffs rising on both sides, and the sense of having the gorge to yourself even on a busy summer weekend, since almost everyone stays on the water rather than the banks.

Arriving at the Pont du Gard by kayak, from underneath, having paddled the whole way there, changes how the bridge feels entirely. It is the same monument, but the approach makes it feel earned rather than simply visited.

Kayak Vert, based in Collias, is the long-established operator for this stretch of the Gardon and publishes current opening dates and water-level conditions on its own site. We recommend checking before setting out, since the route closes in periods of low water.

What it is

A canyon the river carved

The Gorges du Gardon stretch twenty-nine kilometres between Saint-Anastasie and Collias, cut by the same Gardon river that flows beneath the Pont du Gard further downstream. Limestone cliffs rise up to 150 metres above the water in places, and in dry periods stretches of the river disappear underground entirely, resurfacing further along the canyon.

The gorge and its surrounding plateaus were recognised by UNESCO as a Biosphere Reserve in 2015, the only French site honoured that year, and a smaller Réserve Naturelle Régionale of 491 hectares sits within it, on the commune of Sanilhac-Sagriès, the same commune as La Valette Boutique itself.

"Paddling the last bend before the Pont du Gard rises ahead of you, with no road in sight and only the sound of the water, is the best fifteen minutes from La Valette we know."

Beyond the basics

Things worth knowing

150 metres of limestone
The gorge's cliffs rise up to 150 metres above the Gardon in places, carved over millions of years through a limestone plateau, and are among the most respected climbing sites in the Gard, with routes for every level.
A river that disappears
In dry summers, stretches of the Gardon run underground through the limestone and resurface further downstream, a phenomenon typical of this kind of karst landscape and part of why the water level varies so much by season.
Bonelli's eagles overhead
The gorge is one of the more reliable places in the region to see Bonelli's eagle and the Egyptian vulture, alongside a resident colony of European beavers along the riverbanks, most active at dawn and dusk.
The only French site honoured in 2015
When UNESCO named the Gorges du Gardon a Biosphere Reserve in 2015, it was the sole French site recognised that year, out of a global programme covering landscapes valued for both their ecology and their human use.

When to go

Timing your visit

The Gardon's water level, not the calendar, decides whether the kayak route runs. Spring and early summer are the most reliable window.

Best: April to June

Spring

Water levels are highest after winter rain, the gorge is green, and daytime temperatures are comfortable for a few hours on the water without needing an early start.

Good: September to October

Early autumn

Crowds thin considerably once the summer holidays end, and water levels are usually still workable, though it is worth checking conditions the same week.

Depends on rainfall: July and August

High summer

The most popular season, but also the most likely for low water to shorten or close the route in a dry year. Book ahead regardless, and check conditions the morning of.

Practical information

Kayaks, parking and the route

The classic route
8 km, about 1.5 hours
Collias to the Pont du Gard is the standard route, roughly eight kilometres and an hour and a half of paddling on Class I water, suitable for beginners and families with older children. Rental includes a return shuttle from the Pont du Gard back to Collias.
Longer routes
Operators offer routes up to thirty kilometres over one or two days for more experienced paddlers wanting to see more of the gorge itself, upstream of Collias. Book ahead in July and August; the popular eight-kilometre route sells out on hot weekends.
Parking and getting there
Collias is about fifteen minutes from La Valette, mostly on small departmental roads. Parking is available near the rental bases at the entrance to the village; arrive early on summer weekends.
Hiking and climbing
Marked trails follow the top of the gorge on both banks, with viewpoints over the canyon that need no kayak at all. The cliffs near Collias are a well-known climbing area with routes for every level.

Full day combinations

The Gorges du Gardon and the region

A

The gorge and the bridge

Paddle from Collias to the Pont du Gard in the morning, arriving under the aqueduct by early afternoon, then swim in the Gardon before the drive back.

B

Collias and Uzès

A morning on the water, back to Uzès for lunch and an afternoon in the old town, fifteen minutes between the two.

C

Hiking without the kayak

Skip the water entirely and walk one of the marked trails along the plateau above the gorge, with the same views and a fraction of the effort.

D

An early start in summer

Leave La Valette by 8h30 in July or August to be on the water before the heat and the crowds arrive, and to have the best chance of a full-length route if levels are borderline.

Frequently asked questions

About the Gorges du Gardon and Collias

Yes. The Gardon on this stretch is Class I, calm water suitable for first-time paddlers and families with older children. No prior experience is needed.

About 11 km, roughly fifteen minutes by car.

No. The route depends on the Gardon's water level, which is highest in spring and can drop too low to paddle in a dry summer or through autumn and winter. Check with a rental operator before planning a visit outside spring and early summer.

About an hour and a half for the eight-kilometre route, plus time for the return shuttle back to Collias, which is included with rental.

No, though it is often confused with one. It is a UNESCO Biosphere Reserve, a different designation that recognises the landscape's ecological value and its balance with human use, awarded in 2015.

Yes. Marked hiking trails follow both sides of the canyon from Collias, with viewpoints over the gorge, and the area is also a well-regarded climbing destination.
