The Petit Sioulet is the Sioule's younger and quieter sibling — the same water in miniature, running through the same Combrailles granite country, with the same character of wild trout and the same willingness to reward patience.

About this water

The Petit Sioulet is the Sioule's younger and quieter sibling — the same water in miniature, running through the same Combrailles granite country, with the same character of wild trout and the same willingness to reward patience. It's small enough that the main Sioule anglers rarely bother, which is exactly why it's worth bothering with. Short casts, pocket water, the occasional deeper pool where a bigger fish might be lying. Work upstream with a dry-dropper rig and don't linger — cover water, pick the best lies, keep moving. Caddis and stoneflies all season; olives in the right light. Spring and early summer are the prime window, but the upper reaches stay cool enough to fish well into August. A proper backup river when the main Sioule is full of other anglers or running off-colour after a storm.
