Before you travel
Use the authority’s site suggestions and current access notices. Confirm the specific parking area and ground route; a dark-sky plan does not require or justify an unplanned mountain walk after dark.
Local time zone: Europe/London.
Use the official source for directions and the permitted observing area. An exact observing point is not verified here.
Make a private plan for your chosen observing spotEryri's park authority explains its dark-sky landscape and provides a starting point for choosing where to look up. Mountain skylines make the precise observing position important, especially for a target close to the horizon.
Select a lawful, manageable site and verify current parking and access before travel. Compare the actual skyline with the object's direction, and keep weather and the return journey separate from the sky score. A wide accessible view is often a more practical first session than pursuing the darkest possible mountain location. Check the linked source again when planning a later visit.
