Cad East is widely regarded as the best location for photography — particularly for those new to shooting fast jets. Aircraft arrive from your right with noticeably more warning time than most other spots.
On a clear day the views extend to Bala Lake to the east and Snowdon to the north.
The topside angle puts valley walls below the aircraft and open sky above. A 400–600mm equivalent focal length is ideal. Aircraft approach from the right, so position yourself with clear sightlines to that side.
