Blackwater Arboretum / Tall Trees
Hampshire
The Blackwater Arboretum sits in the heart of the New Forest near Rhinefield, where some of the tallest trees in southern England tower overhead in a compact collection of imported conifers and native woodland. This short 2.4 km loop winds through stands of mature Sitka spruce, Douglas fir and occasional coastal redwoods, creating a sheltered, almost cathedral-like atmosphere beneath the canopy. The Blackwater stream crosses the route and the ground is soft with fallen needles throughout. At this length the walk is intimate rather than ambitious, but the scale of the trees overhead gives it a character far beyond its modest distance.
This is a dog friendly walk that works beautifully for shorter outings without sacrificing atmosphere. The dense canopy provides excellent shelter on rainy days, and the carpet of needles is soft and kind on joints, making this ideal for older dogs or those with reduced mobility. The Blackwater stream offers drinking water and a gentle paddle opportunity. Off-lead potential is high as livestock rarely penetrate this deep into the arboretum, and the woodland is open enough beneath the canopy to maintain good oversight. The quieter sections away from the main path give dogs space to investigate the root systems and fallen timber that line the forest floor. A cafe with outdoor seating is available at the Blackwater car park for afterwards.
