The Glen was gifted to the town in 1929. Walkways have been improved, fencing and bridges have been renewed recently, all to give greater pleasure and safety. A recent count listed 1,641 trees in the Glen, and there are some fine examples of beech, birch, oak and ash. Fine views of the Clyde can be obtained from the upper walk, and an old watch tower still stands in ruins at the top of the Glen. This is a shaped and painted stone on the foreshore between Kirn and Hunter's Quay.
Controversy rages around the name.
But nobody really knows. The church stands close by and to the right of the Castle House. In 1816 the ancient Parish Church was replaced by the present building, which was enlarged in 1839, and again in 1911. As early as 1697 there is a notice of a proposed endowment of a Grammar School at Dunoon, but there was clearly a school before this. In 1839 Mr William Campbell of Tilliechewan, who owned the Castle House, presented the clock which still adorns the tower.
