Important
Respect the Land — Keep Access Open

Access depends entirely on the goodwill of private landowners. Please take this seriously.

🚫 Do not do any of the following

✗
Block farm gates, passing places, or private driveways when parking
✗
Leave litter of any kind — carry everything out with you
✗
Cross fences, walls, or gates marked as private land
✗
Disturb livestock or damage crops and hedgerows
✗
Park on verges in a way that blocks visibility or churns the ground
✗
Fly drones — this is active restricted military airspace

If access to any location is lost due to poor visitor behaviour, it affects everyone. A small amount of consideration goes a very long way.

Before You Go
What to Expect on the Day
⚠️
Blank days happen
Some days you'll see nothing. Training cancellations, weather, bank holidays — any of these can mean a quiet sky. Come mentally prepared for this.
📅
No schedule, ever
There is no public timetable. Anyone claiming to know exactly when aircraft will fly is guessing. Plan for two days minimum.
🕗
Arrive early
Most activity falls 09:00–16:00 on weekdays. Being parked and on your hill by 08:30 means you won't miss the first pass of the day.
✈️
It is spectacular
When a Typhoon or F-15 screams past below you at 400+ knots, it is genuinely breathtaking. Even one pass makes the whole trip worthwhile.
🗣
Community shouts
Spotters shout "Incoming!" and pass direction info. The community is welcoming — newcomers are not out of place on any hill.
🥾
Proper hill walking
Most locations need a real climb on rough ground. Boots, waterproofs, food, water, and a paper map are essential — Welsh weather changes fast.
⚠️
This is not an airshow. There is no timetable and blank days are common — aircraft may not fly at all. Most weekdays see some activity, but always plan for the possibility of seeing nothing and treat a busy sky as the bonus it is. Allow at least two full days.
