Cregennan Lakes

High on the shoulder of Cadair Idris, the Cregennan Lakes are two dark upland tarns set in a bowl of rough pasture and drystone walls, with the Mawddach estuary glinting far below and the mountain wall rising behind. It is one of the most photogenic spots in southern Eryri and a world away from the busier honeypots, usually quiet even in summer. The setting is made for aerial work, with the lakes, walls and craggy skyline all in frame. Two things to keep in mind. The land is owned by the National Trust, which does not permit taking off or landing from its property, so launch from the public lane or verge rather than Trust ground, and be considerate. This is also within Eryri National Park, which asks drone users to follow a voluntary code - fly away from livestock, walkers and nesting birds, and avoid the sheep during lambing. There are no airspace restrictions here, but the altitude and open aspect mean the weather turns fast and wind over the ridge can be fierce, so pick a calm, settled day. A still dawn gives mirror reflections on the water and warm light on Cadair Idris - well worth the early climb up the single-track road.
