The WaterfallPostbridge • Waterfall
The Waterfall on the East Dart River near Postbridge represents one of the quieter cascades found within the heart of Dartmoor National Park in Devon, England. This feature occurs where the East Dart River, one of the two main tributaries that eventually form the River Dart, tumbles over exposed granite bedrock characteristic of this ancient moorland landscape. The waterfall itself is modest in scale, typical of Dartmoor's upland streams, where the water descends over a series of granite steps and slabs rather than forming a single dramatic plunge. The appearance and vigor of the flow vary considerably with seasonal rainfall, with the East Dart swelling to a powerful torrent during winter months and subsiding to a gentler cascade over the exposed rock formations during drier summer periods.
The East Dart River rises high on the northern moors of Dartmoor, gathering waters from the blanket bogs and tributary streams that drain the surrounding hills. Its course takes it southward through some of the most remote and beautiful terrain on Dartmoor, flowing past ancient clapper bridges, through wooded cleaves, and across open moorland before eventually joining the West Dart near Dartmeet to form the main River Dart. The catchment area comprises typical Dartmoor geology, dominated by granite tors and outcrops dating back to the Carboniferous period, with acidic soils supporting characteristic moorland vegetation. The river's journey through this landscape has carved out a valley that exposes the underlying granite, creating the natural features and cascades that punctuate its length.
Postbridge itself is perhaps best known for its medieval clapper bridge, one of the finest examples of these ancient granite slab bridges that once provided crossing points across Dartmoor's rivers. The settlement has long served as a waypoint for travelers crossing the moor, and the East Dart River has been an important feature in the lives of moorland communities for centuries. While this particular waterfall may not feature prominently in recorded history or folklore compared to some of Dartmoor's more dramatic features, the East Dart valley as a whole has been witness to human activity stretching back millennia, from Bronze Age settlements to medieval tin streaming operations that exploited the mineral wealth of Dartmoor's rivers.
The landscape surrounding the waterfall embodies the classic character of Dartmoor's river valleys, where the open moorland plateau gives way to more sheltered environments along the watercourses. Ancient oakwoods, known as cleaves, cling to the steeper valley sides in places, providing important habitat for woodland birds and invertebrates. The moorland itself supports populations of Dartmoor ponies, which graze freely across the common land, while birds such as dippers and grey wagtails are frequently observed along the river, perfectly adapted to life in and around fast-flowing upland streams. The surrounding vegetation includes typical moorland species such as purple moor grass, heather, and bilberry, with sphagnum bogs occupying the wetter areas of the catchment.
Access to the East Dart River near Postbridge is relatively straightforward, with the village located along the B3212 road that crosses central Dartmoor between Moretonhampstead and Two Bridges. Postbridge offers limited parking facilities, and visitors should be prepared for busy periods, particularly during summer months and bank holidays when Dartmoor attracts considerable numbers of visitors. From the village, public footpaths and open access land provide opportunities to explore the East Dart valley both upstream and downstream, though visitors should be equipped with appropriate footwear and clothing as conditions can be challenging, particularly during poor weather. The terrain can be rough and boggy in places, and the river should be treated with respect, especially after heavy rainfall when water levels can rise rapidly.
The village of Postbridge itself provides basic facilities including a pub and limited accommodation options, making it a practical base for exploring this part of Dartmoor. The location falls within Dartmoor National Park, and visitors are expected to follow the Countryside Code, respecting the working moorland landscape and its communities. The area is subject to commoners' rights, meaning livestock may be encountered, and gates should be closed behind walkers. The East Dart River valley offers opportunities for longer walks, with routes extending to more remote parts of the moor, though proper navigation skills and equipment are essential for ventures into the wilder parts of Dartmoor, where weather conditions can deteriorate rapidly and mist can disorient even experienced walkers.
