Drone Flying Rules on Anglesey — RAF Valley FRZ & AONB Coastal Restrictions (2026)

Key Rules for Flying a Drone on Anglesey

Anglesey (Ynys Mon) is Wales's largest island, separated from the mainland by the Menai Strait. With ancient castles, dramatic sea cliffs, and over 200 kilometres of coastline, it draws drone operators looking for compelling aerial footage. However, the island hosts two active RAF stations that create significant airspace restrictions across much of its surface.

All UK-wide CAA rules apply on Anglesey. Under 2026 regulations, a Flyer ID is required for drones weighing 100 grams or more, obtained through a free online theory test. Drones weighing 250 grams or more also require an Operator ID at £10.33 per year, which must be displayed on the aircraft. The maximum altitude is 120 metres (400 feet) above the nearest point of the earth's surface, and you must maintain Visual Line of Sight at all times.

You must not fly within 50 metres of people, vehicles, or structures outside your control. This distance increases to 150 metres for congested areas or organised gatherings. These rules apply across England and Wales equally, regulated by the CAA under the Air Navigation Order 2016.

Airspace & Flight Restrictions

RAF Valley FRZ

RAF Valley, on the western coast of Anglesey near Holyhead, is a major Royal Air Force station used for fast-jet and helicopter pilot training. Its Flight Restriction Zone is active 24 hours a day, 7 days a week, regardless of whether flying is taking place. The FRZ extends approximately 2.5 nautical miles in radius from the centre of the aerodrome, from ground level to 2,000 feet, with Runway Protection Zones extending 5 kilometres from each runway threshold.

Flying any drone of any weight inside this zone without written permission is a criminal offence. Requests to operate within RAF Valley's FRZ must be submitted in writing with no less than 7 days notice. Fast jets regularly train at low altitude across Anglesey, creating risks well beyond the FRZ boundary itself.

RAF Mona FRZ

RAF Mona is a satellite airfield for RAF Valley, located in the centre of Anglesey. It also has a permanent FRZ active 24/7, further restricting available airspace on the island. The combined effect of RAF Valley and RAF Mona means that a very substantial portion of Anglesey falls within military restricted airspace.

Between the two bases, military training flights cross the island at low altitude throughout the day and sometimes at night. Hawk fast jets and helicopters are the most common aircraft, and their speed means a drone encounter could be catastrophic.

Caernarfon Airport

Although located on the mainland, Caernarfon Airport (just across the Menai Strait) has its own FRZ that may affect drone flights on the eastern edge of Anglesey. Always check the NATS Drone Assist app to confirm whether your chosen location is clear of all three restriction zones.

AONB Coastline & Heritage Sites

Almost the entire coastline of Anglesey is designated as an Area of Outstanding Natural Beauty. While AONB status does not create an outright prohibition on drone flying, it reflects the landscape's national importance and signals heightened sensitivity to disturbance.

The Anglesey coastline supports breeding seabirds, including puffins on South Stack Cliffs (an RSPB reserve), choughs, and peregrine falcons. Flying drones near nesting sites during the breeding season — typically March through August — risks prosecution under the Wildlife and Countryside Act 1981 if it causes disturbance to Schedule 1 protected species.

Cadw Heritage Sites

Anglesey has several heritage sites managed by Cadw, the Welsh Government's historic environment service. These include Beaumaris Castle (a UNESCO World Heritage Site) and various ancient monuments. Cadw's drone policy requires prior written permission for any drone flight over or near their sites. Flights considered a nuisance or causing a safety incident will be reported to the police, CAA, or Welsh Government Central Safety Team.

Best Spots & Tips for Drone Flying on Anglesey

Despite the military airspace challenges, parts of Anglesey remain accessible for drone flying. The key is thorough planning using the NATS Drone Assist app to identify areas clear of all FRZs.

• Newborough Warren and Llanddwyn Island: The southern tip of Anglesey, potentially outside the main FRZ zones. Stunning beach and lighthouse scenery. Check for wildlife sensitivities as the area is a National Nature Reserve.
• Penmon Point: The eastern tip near Puffin Island. Verify airspace clearance from RAF Mona and check for nesting seabird restrictions from spring through summer.
• Red Wharf Bay: A large sandy bay on the east coast that may offer clearance from military FRZs. Verify with the Drone Assist app before flying.
• Menai Strait: Scenic waterway between Anglesey and the mainland. Be aware of Caernarfon Airport's FRZ and bridge structures that attract visitors (maintaining your 50-metre rule from uninvolved people).

Always check for Temporary Danger Areas (TDAs) and NOTAMs that may impose additional restrictions during military exercises. These can appear at short notice and cover areas beyond the permanent FRZs.

What Happens If You Break the Rules

The military dimension makes airspace violations on Anglesey particularly serious. Flying within an RAF FRZ without written permission is a criminal offence under the Air Navigation Order 2016, carrying fines of up to £2,500. The Ministry of Defence takes drone incursions near military airfields extremely seriously, and incidents may be investigated by both civilian police and RAF Police.

Disturbing protected wildlife at RSPB reserves or breeding sites on the AONB coastline can result in prosecution under the Wildlife and Countryside Act 1981, with potentially unlimited fines for disturbance of Schedule 1 species. Unauthorised flying at Cadw heritage sites will be reported to the police and may result in prosecution or civil action.

Beyond legal consequences, a collision between a drone and a fast jet during training could endanger lives. The RAF has stated publicly that it will pursue legal action against drone operators who compromise aviation safety near its bases.

Your Pre-Flight Checklist for Anglesey

1. Check your registration: Ensure your Flyer ID and Operator ID are valid and displayed on the drone.
2. Check the airspace thoroughly: Use NATS Drone Assist to verify clearance from RAF Valley, RAF Mona, and Caernarfon Airport FRZs. On Anglesey, this step is critical.
3. Check for NOTAMs and TDAs: Military exercises can impose temporary restrictions at short notice. Check on the day of your planned flight.
4. Check heritage site policies: If flying near any Cadw site, seek written permission in advance from Cadw's filming and photography team.
5. Check for wildlife: Identify RSPB reserves and breeding colonies along the AONB coastline. Maintain generous distances from nesting sites, especially March through August.
6. Check the weather: Anglesey's coastal location means strong winds and rapid weather changes. Confirm conditions are within your drone's operational limits.
7. Carry documentation: Keep your Flyer ID, Operator ID, and any permissions accessible in case of a challenge by police, RAF personnel, or site wardens.
