Easan Mor
Easan Mor is a dramatic waterfall located in the remote and rugged landscape near Loch Treig in the Scottish Highlands, formed where the Allt Coire Easain Mor tumbles down steep mountainous terrain. The name itself reflects the Gaelic heritage of the region, with "Easan Mor" translating to "big waterfall," an apt description for this impressive cascade that plunges down the rocky slopes of the corrie from which its feeding stream takes its name. The waterfall is situated in an area characterized by ancient geological formations, where hard metamorphic rocks shaped by glacial activity during the last ice age have created the perfect conditions for spectacular waterfalls to form along streams descending from the high peaks.
The Allt Coire Easain Mor originates in the high corrie on the northern flanks of Stob Coire Easain, one of the prominent peaks in the Grey Corries range, which forms part of the broader Lochaber mountain landscape. This stream gathers water from the steep-sided corrie, collecting rainfall and snowmelt from the surrounding mountains before beginning its rapid descent toward Loch Treig below. The waterfall itself is best characterized as a series of cascades and falls rather than a single vertical drop, with the water tumbling over multiple rock steps and ledges as it navigates the steep gradient of the mountainside. During periods of heavy rainfall or during the spring snowmelt, the volume of water increases dramatically, transforming the falls into a powerful torrent that can be heard from considerable distances across the glen.
The landscape surrounding Easan Mor is quintessentially Highland in character, with the waterfall set against a backdrop of heather-clad slopes, rocky outcrops, and scattered remnants of the ancient Caledonian forest that once covered much of Scotland. The area around Loch Treig remains relatively wild and unspoiled, with limited human habitation and a sense of remoteness that appeals to those seeking solitude in the mountains. The geology of the region is dominated by Dalradian metamorphic rocks, including schists and quartzites that were formed hundreds of millions of years ago and subsequently folded, faulted, and sculpted by successive periods of mountain building and glaciation. The corries and U-shaped valleys in this landscape are classic examples of glacial erosion, and waterfalls like Easan Mor often form where streams tumble over the lip of a hanging valley or where they encounter bands of particularly resistant rock.
Wildlife in the vicinity of Easan Mor includes many species typical of the Scottish Highlands, with red deer being the most commonly observed large mammals in the area. The streams and burns support populations of brown trout, while the surrounding moorland and mountainsides provide habitat for mountain hares, whose coats turn white in winter as camouflage against the snow. Birdlife includes ravens, buzzards, and golden eagles that soar over the high peaks, while ring ouzels and wheatears can be found on the rocky slopes during the breeding season. The area's vegetation varies with altitude, from remnant woodland of Scots pine and birch in sheltered locations at lower elevations to alpine flora on the highest ground, with extensive areas of heather moorland and rough grassland in between.
Access to Easan Mor requires a substantial walk into remote terrain, as the waterfall is not readily accessible by road and lies within an area characterized by its wilderness quality. The nearest road access is from the vicinity of Fersit or from the West Highland Railway line that runs along the eastern shore of Loch Treig, though there are no public roads directly accessing the lochside in this area. Walkers approaching Easan Mor typically do so as part of a longer mountain expedition, perhaps while climbing Stob Coire Easain or neighboring peaks in the Grey Corries range, or while following stalkers' paths that traverse the rough terrain around the upper reaches of Loch Treig. The approach involves crossing pathless or poorly marked ground in places, requiring good navigation skills and appropriate mountain equipment, particularly given the exposed nature of the terrain and the often unpredictable Highland weather.
The waterfall sits within a landscape that has witnessed centuries of human activity, though much of this history has left only subtle traces on the land. The area around Loch Treig was once part of the ancient territory of various Highland clans, and the glens and mountains would have been familiar to generations of shepherds, stalkers, and travelers moving through this part of the Highlands. In more recent history, the construction of the Lochaber hydroelectric scheme in the early twentieth century significantly altered Loch Treig itself, with the loch being dammed and its water level raised to create a reservoir as part of the infrastructure supplying the aluminum smelter at Fort William. However, the upper corries and the waterfall itself remain largely unchanged by these developments, continuing to flow in much the same manner as they have for millennia.
The remoteness and relative inaccessibility of Easan Mor mean that it receives far fewer visitors than many other Scottish waterfalls, preserving its wild character and ensuring that those who do make the effort to reach it are rewarded with a sense of discovery and solitude. The waterfall is best appreciated during or shortly after periods of wet weather when the flow is at its most impressive, though even in drier conditions the cascade retains its appeal as a natural feature within a magnificent mountain landscape. For hillwalkers and mountaineers exploring the Grey Corries or the country around Loch Treig, the sight and sound of Easan Mor tumbling down the mountainside serves as a reminder of the raw elemental forces that continue to shape these ancient landscapes.
