If you want military aircraft at eyebrow height, this is the place. The Mach Loop (officially part of Low Flying Area 7) is a set of linked valleys used by the RAF, USAF units based in Britain, and visiting NATO squadrons for tactical low-level training. Eurofighter Typhoons, F-15s, F-35s, Hawks, Hercules and the occasional helicopter still come through Corris Corner and the Bwlch when the weather and the tasking allow — sometimes below the ridge you are standing on.
There is no ticket, no timetable and no guarantee. The reward is the one thing airshows cannot sell: operational jets working the contours for real.
Late spring through early autumn on weekdays, mid-morning to mid-afternoon, in clear weather. Check enthusiast forums and live spotting feeds on the morning you go; empty hills do happen.
Park legally, stay off private land, keep dogs on leads, and never shine lasers or flash at cockpits. This is a military training area, not a paid display line.

Common questions
Is the Mach Loop open today?
There is no gate and no public timetable. Low flying happens on RAF tasking, almost always on weekdays. Check ADSB-Exchange or enthusiast feeds on the morning you travel — but empty valleys still happen.
Where is the best Mach Loop viewing spot?
The Bwlch and Corris Corner hillsides on the western loop are the classic vantage points. Park legally on the lanes and walk up to the ridgelines.
