One operator, one river, one decision: Aventure Chlorophylle runs a single rafting session on the Gave d'Ossau at 55 € per person. The tour runs 3.5h to 5.5h depending on water conditions, making it a solid half-day commitment. The physical level is occasionally sporty, so it suits beginners who can handle short bursts of effort. Book directly with Aventure Chlorophylle and confirm your slot at least a few days ahead, especially in peak season between May and September.
The session is rated occasionally sporty, meaning you'll hit real rapids with genuine effort required, but it's not a continuous all-out physical challenge. Expect bursts of intense paddling followed by calmer stretches on the river.
The biggest rapids on the Gave d'Ossau deliver the strongest rush. The guide from Aventure Chlorophylle will brief you beforehand so you know exactly when to brace and paddle hard.
No prior experience is required. The occasionally sporty rating means the activity is accessible to first-timers who are reasonably fit and comfortable in moving water.
The season runs from May through September. Early season (May and June) typically brings higher water levels from mountain snowmelt in the Pyrenees, which means faster currents and more powerful rapids.

Equipment
Wear a swimsuit or quick-dry shorts under your wetsuit, and bring a change of clothes for after the session. Given the 3.5h to 5.5h duration and occasionally sporty physical level, closed-toe shoes you don't mind getting wet (such as old trainers or water shoes) are essential.
Getting there
The meeting point is the Oloron-Herrère aerodrome, located at Herrère, 64680, just outside Oloron-Sainte-Marie in the Ossau Valley.
