What the night gives you

Height and distance from towns are what make Spelga good. On a clear, moonless night the stars come out in far greater number than you get near a town, and photographers have caught the Milky Way arching over the reservoir here. Planets and, in season, meteor showers are worth watching for. None of it is guaranteed, though. The sky needs to be clear and the moon low or absent, so check the forecast and moon phase before you set out.

Good to know before you go:

Spelga is a popular start point for guided night hikes into the Mournes, where mountain leaders point out constellations under skies with little light pollution. Meteor showers such as the Perseids in August and Geminids in December are the nights most worth planning around.

The story

About Spelga Dam Dark Sky Spot

You drive up into the Mournes, the road climbs past the last houses, and the reservoir opens out around 1,200 feet up with mountains rising on every side. Away from town light, the sky here goes properly dark on a clear night. Photographers come to catch the Milky Way standing over the water, and in season this is a fine, easy-to-reach spot to watch a meteor shower.
