Airlie and Cortachy Estate is situated in the Angus Glens and cover a wide variety of landscape from moorland to arable farmland. The Estate has been in the Ogilvy family for at least 700 years, though its boundaries have inevitably altered over time. At the present time, it consists of over 30,000 acres, largely in Glens Clova, Prosen and Moy. The family home, Cortachy Castle, which dates back from the 16th century, lies at the heart of the Estate.
The River Walk from Cortachy Bridge to the Sawmill Bridge was originally laid out in the 1870s in anticipation of a visit to Cortachy by Queen Victoria. In the event this visit never took place, but the walk has been carefully and lovingly nurtured and maintained since that period. During the floods of 2015 the Sawmill Bridge was swept away and the lovely circular walk, which is also a core path, was unpassable. In 2017 ScotWays and Airlie Estate funded a new multi-access footbridge across the South Esk and the route was officially opened in March 2018 by Lord Airlie.
