Geltsdale and Old Water loop from Castle Carrock — North Pennines

Embark on the Geltsdale and Old Water loop from Castle Carrock, a moderate hike spanning 6.4 miles (10.3 km) with an elevation gain of 784 feet (239 metres). You can expect to complete this diverse route in about 2 hours and 55 minutes. The trail guides you through the rugged and beautiful landscapes of Geltsdale, featuring a mix of well-defined paths, mountain tracks, and some road sections. As you traverse the isolated Old Water valley, you'll encounter steady ascents and descents, with higher points like Cumrew Fell offering expansive views over the Lakeland fells and the Solway. The varied terrain includes firm tracks, natural surfaces, and potentially boggy sections after rain, ensuring a dynamic hiking experience.

This moderate trail requires good fitness, and while paths are generally accessible, some sections demand sure-footedness. Be prepared for potentially boggy ground, especially after wet weather, and a fairly steep descent through heather near the end of the walk. The route is generally considered to take between 3 to 5 hours to complete, so plan your start time accordingly. While the research does not specify trailhead access or parking details, it originates from Castle Carrock, suggesting this as a convenient starting point for your adventure.

Beyond its natural beauty, the Geltsdale and Old Water loop is rich in industrial archaeology and historical infrastructure. You'll discover old mine workings, disused quarries, and the Geltsdale Pumping Station, alongside Gairs House, once a manager's residence. The area is also significant for its role in Carlisle's water supply, with remnants of the historical water collection system visible, including a metering house. As Geltsdale is an RSPB nature reserve, you might spot wildlife, but be aware that dogs may not be allowed on certain parts of the moor to protect ground-nesting birds.
