“Northumberland International Dark Sky Park is England’s first Dark Sky Park and the largest expanse of dark night sky in the whole of Europe, thanks to minimal light pollution” (Source: Visit Kielder).

According to the Campaign for the Protection of Rural England (CPRE), the star-studded skies above Kielder Water & Forest Park are the darkest in England.

The best time for viewing is during the winter months, when the nights are darkest. Combine this with an awesome trail running route on a great mixture of forest trails then what further incentive do you need to pack your head torch, some warm winter gear & experience this amazing night run set in the beautiful confines of Kielder Forest.
