Hiking

Embark on a moderate 8.1-mile (13.0 km) hike through the Pentland Hills, conquering Carnethy Hill and Scald Law. This loop from Flotterstone features varied terrain, including clear hill paths and rough sections, with steep ascents and descents creating a 'rollercoaster walk' feel. You'll gain 1649 feet (503 metres) in elevation over approximately 4 hours and 42 minutes, enjoying expansive views over Edinburgh, the Firth of Forth, and surrounding hills from the summits. The top of Carnethy Hill is covered by small boulders, while Scald Law offers a spacious, boulder-strewn summit. You will also pass by picturesque Glencorse and Loganlea Reservoirs.

Starting at the Flotterstone Visitor Centre, you'll find convenient amenities including parking and toilets. This popular route requires good fitness and sure-footedness, especially on rough and potentially boggy sections after rain. Be prepared for rapidly changing weather conditions and strong winds on the summits; appropriate layers and sturdy footwear are essential. The Flotterstone Inn nearby provides a place for refreshments after your hike.

This trail offers a significant sense of accomplishment as you reach Scald Law, the highest point in the Pentland Hills. Located less than 30 minutes from Edinburgh, the Pentland Hills are often called the city's 'beauty spot,' making this loop easily accessible for a substantial outdoor adventure. The route also intersects with historical paths like the Kirk Road, once used by worshippers. This diverse landscape of rolling hills, moors, and reservoirs provides a constantly changing and engaging environment.

Glencorse Reservoir

Highlight • Lake

Nestled amongst the Pentland Hills, Glencorse Reservoir is incredibly picturesque. It was built between 1820 and 1824 to provide water to mills in the area and supply drinking water to Edinburgh. Today, the reservoir still supplies water to 450,000 people. The reservoir was created by constructing a dam, which is 77 feet (23.5 m) at its highest point.
