Blank days, radio frequencies, tracking tools, parking rules, drones and more.
No — and this is the single most important thing to know before you visit. There is no public flying schedule. The RAF does not publish daily flying programmes for the Loop. Activity depends on training commitments at individual bases, weather, exercise schedules, and maintenance. Anyone who tells you they know exactly when aircraft will fly is guessing. Treat every pass as a bonus, not an expectation.
More often than you might expect. Blank days — where you see no aircraft at all — happen even in peak season. A sample from June 2023 averaged around 3.5 passes per weekday with a maximum of 15 and a minimum of zero. Some 2024 season days saw 19 passes before 11am, but also days with nothing. Always plan for at least two full days. The walk and the scenery are still worth the trip on a quiet day.
Aircraft typically fly during standard RAF working hours: Monday to Friday, roughly 09:00–17:00. Fridays are often half-days at most bases. No flying on UK bank holidays. USAF aircraft will not fly on US federal holidays. Weekends are almost always quiet. July–September tends to be busiest, with good activity April–October. Winter is significantly quieter.
Two tools are widely used: 360 Radar (free for contributors, subscription otherwise) and ADS-B Exchange (free, global). Not all military aircraft broadcast ADS-B, but many do — watching a Typhoon transit southwest from Coningsby toward Wales in real time is a useful indicator. Community Facebook groups ("Mach Loop" on Facebook) give same-day reports from people already on the hills. Even with aircraft tracked heading toward the area, there is no guarantee they will fly the Loop on any particular sortie.
Yes, though not all are publicly documented. The primary low-flying coordination frequency for LFA7 published in the UK AIP is 130.100 MHz, used by aircraft transiting to and from the Loop area. Some spotters carry handheld airband receivers to listen to traffic, which can give advance notice of inbound aircraft.
Other useful frequencies include the RAF Valley approach/departure frequencies if tracking Hawks transiting from Anglesey. In the UK it is legal to listen to aviation transmissions using an airband radio, but illegal to act on or repeat the contents of private communications. Most spotters use a receiver purely to build general situational awareness.
Quiet days are part of the experience. Walk between locations to see the area from different angles. Visit Corris Craft Centre, Machynlleth, or Dolgellau. Drive the route the aircraft fly to understand the geography. Check Facebook groups to see what others are reporting. Some spotters bring books and enjoy the silence of the Welsh hills — the view from Cad East on a clear day is worth the climb with no aircraft at all.
No. The Mach Loop sits within active restricted military airspace. Flying a drone in or near LFA7 without specific authorisation is illegal and extremely dangerous. Military aircraft fly at very low levels and very high speeds — a collision with a drone could be catastrophic. Any drone activity will result in intervention from authorities and could lead to the Loop being closed to civilian visitors entirely. Do not bring a drone.
Each location guide includes specific parking information. In general: use established lay-bys and roadside pull-offs, never block farm gates or passing places, do not park on soft verges that will be churned up, and do not obstruct access tracks. Farmers use these daily regardless of whether aircraft are flying. If there is no sensible place to park near your chosen spot, drive further away and walk rather than creating problems for local residents.
Signal is patchy to non-existent at most hill locations. Do not rely on your phone for navigation. Download OS maps for offline use before leaving home, or carry a paper copy of OS Landranger 124. Some spotters report improved signal on higher ground, but this is inconsistent across networks and locations.
Most of the best spots sit on or access through privately owned farmland. Access has historically been informal and tolerated by landowners — but this goodwill is not guaranteed and can be withdrawn at any time if visitors behave badly. Leave no litter, close all gates, do not cross fences, and park considerately. The continued availability of these spots depends entirely on the relationship between visitors and local landowners and the farming community.
