Dark Skies over the Llŷn
One of the darkest corners of Wales. No motorways, no cities — just you, the sea horizon, and the Milky Way.
Reading tonight’s sky…
Best Viewpoints
Hand-picked spots for the darkest skies and clearest horizons on the peninsula.
When to Go
Clear, moonless nights are best. The Llŷn’s darkest, longest nights run through winter — but the Milky Way core is at its finest in summer.
Green = long dark nights & clearest skies · Gold = good · Grey = short nights, but summer brings the Milky Way core low in the south.
Stargazing Tips
Make the most of the dark.
Protect your night vision
Use a red-light torch — white light ruins dark adaptation for 20+ minutes. Give your eyes 15 minutes to adjust.
Night photography
Manual mode, ISO 3200–6400, f/2.8 or wider, 15–25 second exposure. Tripod and a 2-second timer. Shoot RAW.
Dress warm
Standing still at night gets cold fast, even in summer. Layers, hat, gloves, and a flask of something hot.
Use a star app
Stellarium (free) or Sky Guide names constellations, planets and satellites as you point your phone up.
Time it right
Best around new moon, on clear nights, from ~90 minutes after sunset once true darkness falls.
Stay safe
Tell someone where you’re going, keep your phone charged, and stick to paths you know in the dark.
