East Cairn Hill at 561m is 1m lower than West Cairn Hill which is 1.5km away to the southwest. The views from the cairn are great, across the southern Pentland Hills and north to the Forth valley.

Harperrig Reservoir was created in 1860 as part of a scheme to create a safe and reliable supply of drinking water for Edinburgh. The dam was raised in 1890 to provide a more reliable source of water to the mills downstream. The reservoir is known to be populated by otters as well as several species of wetland bird and the rare stonefly.

The landscape around Tarbrax is marked by its 19th-century shale mining past. You can see remnants like shale bings on many local trails. For more information on this specific heritage, you can consult resources like the Clydesdales Heritage site.

Sturdy, waterproof hiking boots are essential as many paths, especially around the reservoirs and through moorland, can be boggy and uneven. The weather can change quickly, so it's wise to wear layers and carry a waterproof jacket, even on a clear day. A map and compass or a reliable GPS device are also recommended.
For rewarding views, a hike up one of the nearby hills is your best option. The summits of East Cairn Hill and West Cairn Hill in the Pentland Hills offer panoramic vistas across the Forth Valley to the north and the surrounding southern Pentlands. The East Cairn Hill – Harperrig Reservoir loop from Cairns Castle incorporates one of these excellent viewpoints.
