The last member of the Stewart family to own the estate was Lady Ena Stewart-Bam, who inherited from her grandfather around 1904.
She was the wife of Lt. Col. Sir Pieter C. van B. Stewart-Bam, Kt., O.B.E., a South African soldier, politician and businessman whom she married in 1910.
Today, the forest park is 481 hectares in area and contains a range of wildlife and plants, as well as the remains of four ringforts and a number of megalithic tombs.
Legend has it that these tombs were the beds of Diarmuid and Gráinne in their flight from Fionn Mac Cumhaill.
The forest park also has a picnic and children's play area and a snack outlet called the Ards Coffee Tree.
