Tall Trees Trail
Tall Trees Trail
A woodland walk for all seasons. Stimulate your senses on this short trail around the Forestry England’s Blackwater Arboretum, with its small but nationally important collection of trees from all over the world.
Sensory information boards along the trail provide fascinating facts about the tallest, heaviest and toughest trees in the world. This walk takes you past majestic conifers planted in the 1850s, some of the oldest Douglas fir trees in Britain and includes views of two enormous redwoods. Blackwater has some of the oldest and most striking firs in all of the New Forest. These impressive trees were planted in the 1850s to create what is now known as Rhinefield Ornamental Drive.
