Hillside arboretum with over 150 tree species

There's nothing quite like Kilmun anywhere else in Scotland. The arboretum is home to more than 150 tree species from around the world. Meander through its small forests of silver firs, giant sequoia, coastal redwoods, Oregon maple and Chilean southern beech and you'll wonder why it isn't better known.

Back in 1930, over 260 different species were planted here to see how suitable they might be for Scotland. Many of the trees didn't like our climate or soils, but many have done amazingly well, growing faster and larger than they would at home. Today Kilmun Arboretum is a tree collection of international note and a unique experience for all tree lovers.
