The gardens at Dunninald extend to 100 acres of policies, woodlands and wild garden,  and the Walled Garden is a short walk from the Castle down the Beech Avenue.    The area is host to an abundance of wildlife , and we regularly see red squirrels, roe deer. 

South facing on a slope, the curved northern wall creates a warm micro-climate in the Walled Garden. The trees outside give additional shelter. The main function of the garden was to provide for the household, namely vegetables, fruit and cut flowers. In recent times, the planting has changed to include a double herbaceous border with rose arches down the centre of the garden and mixed borders along the walls. A smaller quantity of vegetables, soft fruits and fruit are still grown. When available, plants, fruit and vegetables are sold when the gardens are open.

The west gate opens onto the site of the previous house. From here visitors have the option of returning to the Castle by the south drive or back up the beech avenue, or taking the longer circular walk around the Wood Path. The wood path is about a mile long.
