Kilmun Arboretum is at the western end of the village, close to Historic Kilmun church and graveyard. Tree lovers can enjoy a stroll through the small forest which is home to over 150 species of trees from around the world, including Japanese cedar, Oregon maple and West Himalayan spruce, as well as redwoods, sequoias and monkey puzzles. There are three walking routes to choose from and they’re open all year. Whilst walking you may be lucky and see red deer, red squirrels and the heronry.
