August 18, 2025, Slieve Loughshannagh Summit

Slieve Loughshannagh is one of the quieter summits in the Mourne Mountains, but it rewards hikers with wide, open views over Silent Valley, Slieve Binnian, and the western Mournes. The climb isn’t too demanding, and the summit has a peaceful, windswept feel, making it a lovely spot to pause and take in the rugged beauty of the landscape.

Lough Money is a quiet, almost mystical place, perfect for relaxing and taking a deep breath. The gentle waves of the lake gently hit the shore, while the reeds sway in the wind, creating a gentle rustling sound. Surrounded by rolling countryside and shady trees, you feel like you've been transported to another world. Ideal for a break on your bike ride.

November 25, 2023, Lough Money

Lough Money is the source for the River Slaney, which flows to the supposed landing spot of Saint Patrick on Strangford Lough. Lough Money’s water is remarkably clear as befits a facility that was once used as a reservoir for Downpatrick. The remains of the disused pumping station still stand on the island. Beautified by the presence of herons, just one of many bird species that comprise an abundance of bird life.
