Flying drones in Brittany: zones, paperwork and contacts

Who it is for

• Companies, local authorities and property owners commissioning a drone job in Brittany (inspection, site monitoring, imagery, mapping)
• Professional remote pilots, French or foreign, operating in the four Breton départements for the first time or occasionally
• Agencies, production companies and event organisers planning a shoot on the Breton coast

What this guide does not do: This guide does not replace checking the Géoportail map and the day's aeronautical publications, nor the official texts · It grants no authorisation and does not guarantee the agreement of a military authority, an airport or a nature-site manager · It does not cover the general rules in depth (categories, training, registration): that is the job of the general guide

Introduction

This regional edition is for anyone who has to fly a drone in Brittany, or have one flown, for professional purposes: an asset manager scheduling roof inspections in Rennes and Lorient, a coastal authority monitoring its shoreline, a food-industry group wanting a site video, or an operator from another country discovering Finistère. It gathers, département by département, everything specific to Brittany: the Brest no-fly zone, the three naval air stations, airport control zones, coastal nature reserves, the préfectures that receive flight notifications, and the major events.

Start with chapter 1, which sets out the seven Breton reflexes. Then use the decision table in chapter 8 and the checklist in chapter 9 for every mission: both are designed to be printed and kept in the flight file. Chapters 2 to 7 are reference material for when an address falls inside a particular zone.

This guide is up to date as of 30 September 2026. It reflects the framework in force since 1 January 2026: the former French national scenarios S1/S2/S3 can no longer be used (operators rely on the European standard scenarios STS-01 and STS-02, or on an authorisation); professional open-category flights over public space in built-up areas are allowed by the order of 23 December 2025 (no overflight of people, daytime only); and a prior notification must reach the préfecture at least 10 working days before any flight over a populated area.

What changes when you fly in Brittany

Brittany is not the most restricted region of France everywhere, but it concentrates a few very strong constraints in specific sectors. Seven things to know before promising a date to a client.

1. A permanent prohibited area covers the Brest roadstead. Zone LF-P 112 Brest, created by the order of 28 June 2024, extends from the surface to flight level 195 (about 5,950 m) and is active 24 hours a day. It covers the roadstead and much of the Crozon peninsula, around the Île Longue ballistic-missile submarine base. There is no free height band for a drone: the zone is avoided, or subject to a specific procedure with the French Navy with no guaranteed outcome.

1. The French Navy is a stakeholder in its own right. The Atlantic maritime zone command (CECLANT), in Brest, manages the Navy's prohibited areas in western France. Access requires a letter of agreement (average stated lead time: 20 working days), then a derogation request for each flight (minimum notice: 10 working days). Since 1 September 2023, derogations for promotional purposes are no longer granted.

1. Three naval air stations shape the airspace. Landivisiau and Lanvéoc-Poulmic in Finistère, and Lann-Bihoué near Lorient, which also hosts Lorient Bretagne Sud civil airport. Around them, military control zones and low-level traffic require coordination.

1. Every major town has an airport nearby. Rennes, Brest, Lorient, Dinard-Saint-Malo and Quimper have control zones; Vannes, Saint-Brieuc, Lannion and Morlaix have aerodromes. In these areas the Géoportail map shows reduced maximum heights, sometimes zero close to the runways: flying higher requires the airspace manager's agreement.

1. The coastline is protected in successive layers. The Iroise marine nature park, national nature reserves (Iroise, Sept-Îles, Saint-Brieuc bay, Séné marshes), the Armorique and Gulf of Morbihan regional nature parks, Natura 2000 sites: a coastal flight is prepared with the site manager, especially during bird nesting and wintering seasons.

1. Wind decides as much as the rules do. The Brest-Guipavas weather station records on average close to 68 days a year with gusts above 58 km/h. Every Breton mission needs a multi-day window and a fallback date, including in the préfecture notification.

1. Large gatherings are frequent and recurring. The Lorient Interceltic Festival, the Vieilles Charrues in Carhaix, the Transmusicales in Rennes, the Brest maritime festival, offshore race starts in Saint-Malo: they usually trigger temporary restrictions. The 2026 Route du Rhum starts from Saint-Malo on 1 November, with a race village open from 20 October.
