Join a Sunday guided walk and see Dawyck's stunning collection of rhododendrons and other spring highlights. Celebrate the Scottish Rhododendron Festival with a guided walk at one of the world’s finest arboreta. The climate at Dawyck is suited to hardier, higher altitude species which have proved their tolerance to cold winters, late spring frosts and uncertain summers. As well as a stunning collection of rhododendrons, you will see some of Britain’s oldest and tallest trees. The walk, which is free with normal Garden admission, will last approximately one hour.
