Night Carp Fishing in Isère

The essentials in 20 seconds

Night carp fishing is legal in Isère on designated stretches defined by prefectural decree. Vegetable baits and boilies only, catch-and-release is mandatory. Geocarp lists 20 verified night venues in this department, with maps, access details and angler reports — in English.

Isère works differently from most French departments, and you need to understand that before booking: night carp fishing is not open continuously, it is granted as temporary authorisations to named angling clubs on a calendar of weekends set each year. Five venues carry it. The Grésivaudan valley clubs run the grand and petit Lône at Pontcharra and the Vernay lake at Chapareillan, both under the Chartreuse and Belledonne ranges. On the edge of Grenoble, the EDF canals at Saint-Égrève are open to the city club and get the most weekends of any site. Up in the Matheysine plateau, the Étang du Crey at Susville sits at altitude in mountain country, and further west the Chanclau lake at Saint-Étienne-de-Saint-Geoirs and the Maurice Dumoulin lake at Saint-Bonnet-de-Chavagne complete the list. The scenery is exceptional — few places let you fish under 2,000 m peaks — but the calendar is the constraint: check the current year's dates before you plan anything, because they change annually and the sessions run Friday or Saturday evening to the following morning. No carp may be held or moved during the night hours, and live carp over 60 cm may never be transported.

Frequently asked questions

Is night carp fishing legal in Isère, France?

Yes, on designated stretches defined by prefectural decree. Geocarp lists these venues with maps, access details and angler reports.

Do I need a French fishing licence?

Yes. A valid French fishing licence (carte de pêche) is mandatory and can be bought online at cartedepeche.fr. Some venues require an additional night carp option from the local angling club (AAPPMA).

What baits are allowed at night in France?

Vegetable baits and boilies only. Any carp caught at night must be released immediately — keeping or transporting carp at night is prohibited by French law (decree 2004-599).

Is the Isère (38) a good destination for a night carp fishing trip from the UK?

Only if you plan around its calendar. Night carp fishing in Isère is granted as temporary authorisations to named clubs on set weekends, renewed each year by a new prefectural order, rather than being open continuously. Five venues carry it: the EDF canals at Saint-Égrève on the edge of Grenoble, which get the most dates; the grand and petit Lône at Pontcharra and the Vernay lake at Chapareillan in the Grésivaudan valley; the Étang du Crey at Susville on the Matheysine plateau; the Chanclau lake at Saint-Étienne-de-Saint-Geoirs; and the Maurice Dumoulin lake at Saint-Bonnet-de-Chavagne. Sessions run from evening to the following morning across a weekend. The setting is alpine and hard to beat, but confirm the current dates with the federation before committing. No carp may be retained or moved during the night hours, and no live carp over 60 cm may be transported at any time.
