Paddling under the Pont d’Arc and snorkeling beside Port-Cros belong to very different French holidays. Inland rivers need a suitable water level and a plan for getting back to your start. Mediterranean snorkeling depends on the sea forecast and the opening of managed underwater trails.
Plan each outing separately. The table compares physical effort; technical difficulty and exposure can differ. Each mission on the map has its location and preparation details.

Choose your time on the water
Pick Pont d’Arc for a short river descent or the Tarn for a longer day in a gorge. Chenonceau puts the château’s arches on the paddling route. The Ubaye is the white-water choice; La Palud and Peyrefite suit swimmers who want marked underwater interpretation routes.
Canoe beneath the Pont d’Arc

Take the short Vallon-Pont-d’Arc to Châmes descent by canoe or kayak, including small rapids and the passage directly beneath the Pont d’Arc. It is an introductory river route, but you still need to be comfortable on moving water.
Passing under the arch shows directly how the Ardèche has cut through the limestone at the entrance to the gorge.
Hire a canoe or kayak from a local operator for the boat, safety equipment and shuttle logistics. Operators set their own age and swimming requirements, which you must meet. Go only when river and weather conditions are suitable and follow the operator’s briefing.

Launch by canoe or kayak near Chenonceaux and paddle along the Cher toward the château. You pass directly beneath the arches carrying the gallery from one bank to the other, then continue or turn back according to the route you hired.
Chenonceau is built across the Cher. From a canoe, you pass beneath the gallery arches and see the château from the water.
Hire a canoe or kayak from a local operator for the boat, buoyancy equipment, briefing and any shuttle included with your route. Follow the operator’s swimming, age and safety requirements, and check river and weather conditions before departure.
View in GoExploringCanoe the Tarn Gorge from Sainte-Enimie

Launch around Sainte-Enimie and follow the Tarn downstream through the gorge, alternating calm pools with faster water beneath the limestone walls. Routes of around 15–21 kilometres make a solid day on the river without requiring white-water technique.
You follow the Tarn along the bottom of the limestone gorge it carved.
Confirm the rental base is operating for your dates and arrange the return shuttle. Check water levels and meet the operator’s swimming and age requirements before launching.
View in GoExploringRaft the Ubaye from Le Martinet to Le Lauzet
Join a guided raft at Le Martinet and descend the Ubaye toward Le Lauzet. On this classic section you paddle as a crew through a series of strong rapids, responding to the guide while the river level changes the exact lines and difficulty.
The Martinet-to-Lauzet run is one of the Ubaye valley’s established white-water routes.
Book a professional rafting provider; a certified guide and specialist equipment are required. For this classic section, one current operator sets a minimum age of 14, while requirements can vary with water level and provider. You must be able to swim and submerge yourself; check the operator’s current conditions before booking.
View in GoExploringSnorkel La Palud’s underwater trail
Swim out from Plage de la Palud with fins, mask and snorkel and follow six interpretation buoys through shallow protected water. The circuit takes about 40 minutes and passes seagrass, rocky habitat and the fish and invertebrates that use them.
La Palud’s six marked stops introduce the marine life of Port-Cros National Park along a defined route through protected water.
The trail is free for autonomous swimmers, but you need fins, a mask and snorkel and must reach Port-Cros by boat before walking to the beach. Don’t enter in strong Mistral conditions, and check current park and sea notices before swimming.
View in GoExploringSnorkel the Peyrefite Underwater Trail
Swim from Peyrefite beach with fins, mask and snorkel along a 250-metre marked route. Five buoys divide the trail into pebbles, Posidonia seagrass, boulders, crevices and drop-off habitats, with submerged panels explaining what you are passing.
The trail puts marine interpretation inside the Cerbère-Banyuls reserve itself. You move through five different shallow-water habitats while learning about the ecosystem you are swimming over.
The trail is free with your own mask, snorkel and fins and is listed for the June-to-September season. The staffed reception point normally operates in July and August, when equipment may be available to rent. Check sea conditions and current reserve notices before entering, and do not touch, feed or remove marine life.
View in GoExploringBefore you set out
For river trips, confirm the operator’s swimming requirements and included safety equipment before paying. Check conditions along the full route, beyond the sheltered launch. On the underwater trails, keep clear of sensitive habitat. Follow any decision by the guide or park to shorten or cancel the outing.
