Eas Mòr (upper)
Eas Mòr, meaning "big waterfall" in Scottish Gaelic, is the upper waterfall on the Abhainn Ghil stream on the island of Islay in Scotland's Inner Hebrides. This waterfall represents one of the more substantial cascades on this rugged and remote Scottish island, though it remains relatively unknown compared to Islay's famous whisky distilleries. The waterfall is located in the northeastern part of the island, in terrain characterized by the ancient metamorphic rocks that form much of Islay's geological foundation. The Abhainn Ghil flows through a landscape shaped by both ancient geological processes and more recent glacial activity during the last ice age, which carved out the valleys and glens that give the island its distinctive topography.
The Abhainn Ghil itself is a relatively short watercourse that drains the moorland areas in this part of Islay, gathering water from the peaty uplands before tumbling down toward lower elevations. Like many Scottish waterfalls, Eas Mòr's character varies dramatically with rainfall and seasonal conditions. During periods of heavy rain, which are common in the western Highlands and Islands, the waterfall can transform from a modest cascade into a powerful torrent, with the dark, peat-stained water creating a striking contrast against the pale rock faces. In drier summer months, the flow may diminish considerably, though the waterfall rarely runs completely dry due to the generally wet climate of the region.
The landscape surrounding Eas Mòr is typical of Islay's wilder interior, with heather moorland, rough grassland, and areas of bog creating a habitat that supports the island's diverse wildlife. Islay is renowned among naturalists for its bird populations, particularly its wintering geese, though the interior uplands where this waterfall is located are more likely to host red deer, mountain hares, and upland bird species such as golden plover and red grouse. The burns and streams that feed into the Abhainn Ghil may also support otters, which are found throughout Islay's freshwater systems, though sightings in this remote area would be relatively rare given the elusive nature of these mammals.
Access to Eas Mòr is challenging, reflecting its location in one of the less-visited parts of Islay. The OS grid reference NR288433 places it in rough, pathless terrain where navigation skills and appropriate equipment are essential. Unlike some of Scotland's more celebrated waterfalls that have been developed with viewing platforms and maintained paths, this waterfall requires a genuine hillwalking expedition to reach. The nearest roads are some distance away, and visitors would need to be prepared for walking across uneven moorland, potentially boggy ground, and stream crossings. This remoteness is part of the waterfall's appeal for those who do make the effort, offering a sense of wilderness that is increasingly rare even in the Scottish Highlands and Islands.
The geology underlying Eas Mòr and the Abhainn Ghil consists primarily of Dalradian metamorphic rocks, ancient sedimentary deposits that were transformed by heat and pressure during mountain-building episodes hundreds of millions of years ago. These rocks, which include schists and quartzites, form much of the bedrock of Islay and create the resistant bands over which waterfalls like Eas Mòr cascade. The erosive power of the stream, particularly during periods of high flow, continues to shape the waterfall's character, though on the geological timescale this is an extremely slow process. The dark color of the water, typical of streams flowing through peatland, comes from dissolved organic compounds leached from the extensive peat deposits that blanket much of Islay's uplands.
Islay's cultural landscape is rich with Gaelic heritage, and the very name of the waterfall reflects the continuing importance of the Gaelic language on the island, where it remains more actively used than in many parts of mainland Scotland. While I am not aware of specific folklore attached to Eas Mòr itself, waterfalls throughout the Highlands and Islands traditionally held significance in local culture, sometimes associated with supernatural beings or used as landmarks in oral histories and territorial boundaries. The remote location of this particular waterfall means it likely featured less prominently in settlement patterns and stories than more accessible water features, though it would certainly have been known to shepherds, hunters, and others who traversed these uplands in centuries past.
