The grounds at Ardnavaha include about eight acres of gardens, which include a walled garden, a croquet lawn, an old orchard and a tennis court in the upper lawn. At the front of the house is a gently sloping lawn which goes to a lake at the bottom of the garden, where ducks, swans and herons can often be seen.The two large Cedars by the Croquet Lawn are among the oldest trees in Munster. The gardens are a perfect location for picnic’s during the summer.
