Boulsworth hill is a large expanse of moorland, the highest point of the South Pennines of south-eastern Lancashire, England, separating the District of Pendle from Calderdale.
Its summit, Lad Law, commands views over Pendle Hill, the Forest of Bowland, the Yorkshire Dales, and the South Pennines. The Brontë Way and the Pendle Way both pass along the slopes of Boulsworth Hill, providing routes of ascent from Nelson and Wycoller. A further possibility is to climb from Trawden, the nearest town to the summit, and it was originally intended that Boulsworth Hill would be a highlight of the Pennine Way, which instead passes to the east of the hill. Following the CRoW Act, Boulsworth Hill can now also be legally climbed from the Yorkshire side, near Hebden Bridge.
The underlying rock is Millstone Grit, which is seen outcropping in several places and forming a steep scarp face along the summit. The hill is covered by acidic grassland,which provides a valuable breeding ground for red grouse, twite, golden plover and other birds.
Boulsworth hill lies just inside Lancashire, although the county boundary with Calderdale passes just a mile to the southeast of Lad Law.
This cache and other similar caches were originally placed by CharlieG0PZO for Radio Amateurs,who are taking part in the "Summits on the Air" programme. As they are hidden on mountain tops they will be of interest to geocachers who are fell walkers.
