Where to go
- Marais du Vigueirat / Camargue ditches — Marsh frogs and Mediterranean tree frogs; rice-field pumps run at night in May. Map
- Brenne ponds (Chérine area) — European tree frog stronghold; roadside ponds are enough. Map
- Marais poitevin (Coulon) — Canal network — hire a flat boat at dusk for an in-the-chorus position. Map
- Landes dunes (Réserve d'Arjuzanx / Courant d'Huchet) — Natterjack toads in the dune slacks and old mine pools. Map
How to go on your own, and what it costs
Roadside ditches and ponds: the Camargue D36/D37 verges, Brenne roadside ponds around Chérine, the Marais poitevin canal paths at Coulon (flat-boat hire optional), the Courant d'Huchet dune paths. All free; stay off private banks.
Cost: Free; Marais poitevin boat hire optional (check current prices).
Field-recording notes
SPLs at the ditch edge are high — back off 10–20 m for balance and pad if going close. Introduced marsh frogs now dominate much of southern France and drown out native species; the Brenne still has clean tree frog choruses. Everything here is protected — no capture.
