Via Ferrata · Millau
How to choose
Both routes are operated by Nature et Sensations, run in French and English, and sit at an "Occasionally sporty" physical level, so the real differentiator is intensity and time. The Boffi via ferrata costs 40 € for a half-day: a compact session that suits first-timers who want to test their grip on iron rungs and exposed rock faces without committing to a long day. The Liaucous route above the Tarn Gorges runs 4h and costs 42 €, placing you high above one of southern France's most dramatic river canyons. For just 2 € more, you get significantly more vertical exposure and a longer sustained adrenaline window. Pick Boffi if it's your first via ferrata. Pick Liaucous if you're ready to push further along the cliff line.

Frequently asked questions
Which route is more intense, Boffi or Liaucous?
Liaucous runs for 4h above the Tarn Gorges, meaning longer sustained exposure on the rock face. Boffi is a half-day session, shorter and better suited to beginners getting their first taste of clipped-in climbing.
Do I need prior climbing experience for these via ferratas?
No prior climbing experience is required. Both routes are rated "Occasionally sporty", meaning they demand some physical effort and comfort with heights, but not technical climbing skills.
What is the most intense moment on the Liaucous route?
The route traverses cliffs directly above the Tarn Gorges, so the peak intensity comes during the exposed traverse sections where the river gorge drops away beneath you. The 4h duration means that exposure is sustained, not just a single moment.
Is there a minimum age or weight requirement?
The listings do not specify age or weight limits. Contact Nature et Sensations directly before booking to confirm requirements for your group.
When is the best time of year to book?
Via ferrata season around Millau runs from May through October. July and August see the highest demand, so book ahead for those months.

Practical info
Equipment
Harness, helmet and via ferrata lanyard (Y-shaped energy-absorbing set) are typically provided by Nature et Sensations, but confirm at booking. Wear closed-toe shoes with a firm sole, bring water and dress in layers since cliff faces in the Millau area can be exposed to wind even in summer.
Getting there
The Boffi session starts at the Boffi via ferrata car park in Millau (12100), while the Liaucous route meets at the Liaucous church car park on the D907 in Mostuéjouls (12720), roughly 20 km north of Millau along the Tarn Gorges road.
