Isle of May
The Isle of May is a small, dramatic island lying in the outer Firth of Forth, approximately 8 kilometres off the East Neuk coast of Fife in Scotland. Despite its modest size — roughly 1.8 kilometres long and less than half a kilometre wide — it punches far above its weight in terms of ecological, historical, and scenic significance. It is one of Scotland's most important seabird colonies, a Site of Special Scientific Interest, and a National Nature Reserve managed by NatureScot. Visitors come from across the world to witness the extraordinary spectacle of tens of thousands of seabirds, most famously Atlantic puffins, nesting in dense burrows across its cliffs and grassland. The island has the character of a place that exists entirely on its own terms — wild, windswept, and utterly captivating.
The island's human history stretches back at least to the early medieval period. Saint Ethernan, an Irish or Pictish missionary also known as Adrian, is said to have established a religious community here in the ninth century. According to tradition, he and his companions were massacred by Viking raiders, likely around 875 AD, transforming the island into a site of Christian martyrdom. A priory was subsequently founded in his honour, and the ruins of the Benedictine Priory of St Adrian — established in the twelfth century — are still visible today, making the island one of Scotland's earliest pilgrimage destinations. During the medieval period, pilgrims sailing to St Andrews would often stop at May as part of their devotional journey, and the island possessed considerable religious prestige.
Later centuries brought different uses to the island. A lighthouse was established on the Isle of May as early as 1636, making it one of the first lighthouses in Scotland. That original light was a coal-burning beacon maintained on top of a stone tower, succeeded in 1816 by the existing lighthouse, which was designed by Robert Stevenson — grandfather of the writer Robert Louis Stevenson — in the characteristic style of the Northern Lighthouse Board. The lighthouse itself is a handsome, whitewashed structure that stands out sharply against the grey-green cliffs and the open sky. The island also has a melancholy wartime history: during the First World War it served as a base for submarines, and in 1918 the submarine K13 was raised after a catastrophic accident in the Gareloch, only to be renamed K22 and then involved in the disastrous "Battle of May Island" in January 1918, when a series of collisions in the Firth of Forth resulted in the loss of two submarines and more than a hundred lives.
In person, the Isle of May is a place of intense sensory experience. The moment you step ashore — assuming the sea conditions allow — you are engulfed by sound: the overlapping calls of thousands of seabirds, the crash of waves against the dolerite cliffs, and the constant, salt-laden wind that seems to blow without pause. The ground beneath your feet is riddled with puffin burrows, requiring careful walking, and the birds themselves show almost no fear of humans, going about their nesting business within arm's reach. Guillemots and razorbills pack every ledge of the cliffs in dense, raucous ranks. Shags stand on rocky outcrops with wings outstretched, drying themselves with heraldic dignity. In the quieter corners of the island, grey seals haul out on lower rocks, and the island supports a large breeding colony. The smell is briny, sharp with guano, and entirely elemental — the smell of a living, functioning wilderness crammed into a small space.
The physical landscape of the island is shaped almost entirely by its geology and exposure. It is formed from a sill of hard dolerite rock — the same dark volcanic intrusion that forms the Bass Rock a little further west — which resists erosion and produces vertical cliffs on the eastern and northern sides, while the western side slopes more gently into the sea. The interior is an undulating carpet of sea campion, thrift, and coarse grass, broken by the ruins of the priory, the lighthouse buildings, the remains of a later Low Light beacon, and the research facilities of the island's bird observatory. In summer, the wildflowers add splashes of pink and white against the dark rock, and the whole island has an intensity of colour that feels almost theatrical under clear skies.
The surrounding waters and coastline of the Firth of Forth provide the broader context. The East Neuk of Fife — with its charming fishing villages of Anstruther, Pittenweem, Crail, and St Monans — lies to the northwest and west. The Bass Rock, another famous gannet colony and historic fortress, is visible to the southwest. On clear days, the hills of East Lothian and even the distant outline of Edinburgh can be made out. The Firth itself is a busy waterway, and seals, dolphins, and occasionally minke whales are seen in these waters, adding to the wildlife spectacle on and around the island.
Visiting the Isle of May requires planning, as it is only accessible by boat and the sea conditions in the Firth of Forth can be changeable. The main departure point is Anstruther, a short drive from St Andrews, from which a small number of licensed boat operators run day trips during the visitor season, which typically runs from late April to September. The most popular period is May and June, when puffin numbers are at their peak and the noise and activity of the colony is at its most overwhelming. Visitors are given a few hours ashore and are asked to follow marked paths to protect the fragile nesting habitat. Numbers are restricted to protect the wildlife, so advance booking is strongly recommended, particularly during peak months. The boat crossing takes roughly forty-five minutes each way depending on sea conditions, and can be rough; visitors prone to seasickness should come prepared.
One of the island's more unusual distinctions is that it has been home to a continuous bird-ringing and monitoring station — the Isle of May Bird Observatory — since 1934, making it one of the longest-running bird observatories in the United Kingdom. Researchers and dedicated birdwatchers can apply to stay in the observatory accommodations for extended periods, experiencing the island through the lens of careful scientific observation. The island is particularly notable during autumn migration, when rare and unusual birds blown off course appear in the island's sheltered patches of cover, attracting twitchers from across Britain. The combination of world-class seabird breeding colony, medieval religious history, lighthouse heritage, and serious scientific work makes the Isle of May one of the most layered and rewarding small islands in the whole of the British Isles — extraordinary in almost every dimension, and yet still quietly, stubbornly off the radar for most visitors to Scotland.
