Great Mis Tor
Great Mis Tor is one of the most distinctive and commanding granite tors on Dartmoor, rising to approximately 538 metres above sea level on the high moorland of the Dartmoor National Park in Devon, England. It forms one of a pair with Little Mis Tor, which stands nearby to the southeast, and together they create a dramatic skyline feature visible from considerable distances across the open moorland. The tor is composed of the characteristic coarse-grained Dartmoor granite, shaped by millions of years of weathering and periglacial activity into a series of stacked and fractured rock piles that give it a rugged, almost architectural quality. It is considered one of the more substantial and rewarding tors on the northern moor, attracting hikers, photographers, geologists and those simply drawn to its wild and exposed atmosphere.
The geology of Great Mis Tor, like all of Dartmoor's tors, is rooted in the intrusion of granite magma into older surrounding rock during the Carboniferous and Permian periods, roughly 280 to 300 million years ago. Over vast stretches of geological time, the overlying rock was eroded away, and the resistant granite was left exposed to freeze-thaw cycles during the Ice Age, which fractured and shaped the rock into the dramatic formations seen today. The word "tor" itself is thought to derive from an Old English or Celtic word for a high, rocky outcrop or peak, and the Dartmoor landscape is studded with dozens of them, each with its own distinctive character and name accrued over centuries of human habitation and land use.
In terms of human history, the area around Great Mis Tor has been inhabited and traversed since prehistoric times. Dartmoor as a whole contains one of the richest concentrations of Bronze Age remains in Britain, including stone rows, stone circles, cairns and hut circles, many of which can be found within walking distance of the tor. The open moorland was used for grazing and ritual activity by prehistoric communities, and the landscape retains a haunting sense of long human presence despite its apparent wildness. In more recent centuries, the moorland around Mis Tor formed part of the ancient Dartmoor Forest, a royal hunting preserve, and the boundaries of this territory were marked and contested over the medieval period.
Great Mis Tor also lies close to one of the most significant military firing ranges on Dartmoor, the Merrivale Range, which is used by the British Army. This is an important practical consideration for visitors: access to the area may be restricted during live firing exercises, which are scheduled on certain weekdays and some weekends. Red flags fly at the range boundaries when firing is in progress, and visitors must check the firing timetable in advance. Despite this, the area is accessible and freely visited on most days, and the military presence, while an unusual backdrop, has also served to preserve the raw, undeveloped character of the landscape by limiting development and intensive agricultural use.
Standing on or beside Great Mis Tor, the experience is one of elemental exposure and vast open space. The summit rocks rise up in a cluster, and from the top one has panoramic views across the high moor in virtually every direction, taking in other prominent tors including Roos Tor, Cox Tor, and on clear days the profile of Yes Tor and High Willhays, the two highest points on Dartmoor. The wind on the tor can be fierce and constant, carrying the sound of distant streams and occasionally the bleating of the hardy Dartmoor ponies and sheep that graze freely across the surrounding grass and bog. The granite underfoot and around you is rough-textured, often furred with grey and orange lichen, and the rock surfaces are pitted and grooved by centuries of weathering.
The surrounding landscape is quintessential northern Dartmoor: a mix of rough grass, bracken, boggy hollows and the occasional clitter field — an expanse of scattered boulders that has tumbled down from the tor over geological time. The River Walkham rises not far from this area, and several small streams cut across the moorland in the vicinity. The village of Merrivale lies just to the south, and it is notable for the Merrivale Stone Rows, one of the best-preserved and most accessible prehistoric ceremonial landscapes on Dartmoor, featuring a double stone row, a stone circle and several cairns arranged across the open hillside. The B3357 road between Tavistock and Two Bridges passes through Merrivale, making this one of the more accessible corners of the high moor.
For visitors planning a trip, the most practical starting point is the car park at Merrivale or the roadside parking along the B3357. From there, Great Mis Tor is a relatively straightforward walk of around one to two kilometres across open moorland, with a modest but steady ascent. No formal path leads to the summit, and moorland navigation skills are recommended, as the terrain can be boggy and visibility can change rapidly. Stout waterproof footwear is essential year-round. The best conditions for visiting are on clear days between late spring and early autumn, though the tor has a particular atmospheric quality on misty autumn mornings or in winter snow. Sunrise and sunset visits reward photographers with dramatic light playing across the granite and the wide horizons.
One of the more intriguing and lesser-known features of Great Mis Tor is the presence of rock basins on its summit stones — naturally formed hollows in the granite surface that collect rainwater. These basins were once believed by antiquarians to have been carved deliberately by Druids for ritual purposes, a theory that fired the Victorian imagination but has long been dismissed by geologists and archaeologists, who understand them as the result of natural weathering by water pooling in depressions and slowly enlarging them through chemical and physical erosion. Nonetheless, the folklore of Dartmoor is rich with associations between its tors, rocks and ancient spiritual practices, and the sense of mystery that pervades the high moor is difficult to entirely explain away by rational means.
Great Mis Tor represents something of a gateway to a deeper understanding of Dartmoor's layered character — a place where geology, prehistory, military history and raw natural beauty converge in a way that few other locations in southern England can match. It is not a manicured heritage site or a managed viewpoint, but simply a place where the land has been shaped by time and weather into something extraordinary, and where the visitor must come prepared and on the landscape's own terms. For those willing to make the effort, it rewards with a genuine sense of wildness and perspective that is increasingly rare in modern Britain.
