A Sanctuary for Seabirds and Seals

The Isle of May is a tiny island, approximately 1.5 km long and 0.5 km wide, nestled at the mouth of the Firth of Forth. Despite its modest size, it supports one of Scotland's most impressive natural spectacles. Each spring and summer, the island's cliffs become a bustling city for over a quarter of a million seabirds, including puffins, guillemots, razorbills, kittiwakes, and arctic terns. Visitors can follow cliff-top paths that provide dramatic views of these bird colonies, where the cacophony of calls and the sight of colorful puffin bills create an unforgettable wildlife experience.

Rich Layers of History and Culture

Beyond its natural wonders, the Isle of May has a deep and varied history. It has been a place of spiritual significance since the 9th century, with early Christian churches established by monks. Over the centuries, the island also served as a haven for smugglers and a beacon for mariners navigating the Firth of Forth. Archaeological remains, including prehistoric burial sites, add to the island’s cultural tapestry, making it a place where nature and human heritage intertwine.

Visitor Facilities and Experiences

The reserve features a small visitor centre nestled on a slope overlooking the main harbour, offering natural history displays and sheltered viewing areas with large windows. Outside, information panels detail the island’s wildlife and history. Well-maintained paths vary from level and surfaced to steeper, rougher trails near cliffs, catering to different levels of mobility. Seasonal guided tours enrich the visitor experience, revealing insights into the island’s ecology and stories. The best time to visit for seabird watching is from May to July, while autumn brings the largest breeding colony of Atlantic grey seals in eastern Britain.

Wildlife Highlights Throughout the Year

Spring marks the arrival of seabirds gathering to breed, with courtship displays and the soft cooing of eider ducks near pathways. Summer is the peak breeding season when birds rear their young, filling the island with life and sound. Autumn shifts the focus to grey seals, which come ashore to breed on the island’s rocky coasts. The island also serves as a critical stopover for migrating birds, with over 250 species recorded during migration seasons.

Geological and Botanical Features

The island’s landscape is shaped by volcanic basalt rock formations, with steep gullies, monumental rock stacks, stone arches, and caves along the cliffs. A thin layer of soil supports wildflowers such as buttercups, daisies, ragwort, and silverweed, attracting various butterflies and moths, including rare species. The island’s unique lichen species add to its botanical interest, enhancing the sense of a wild, vibrant ecosystem.

Conservation and Management

Managed by NatureScot, the Isle of May is one of Scotland’s National Nature Reserves, protected for its outstanding natural heritage. Access is controlled to minimize disturbance, with visitor numbers limited during sensitive breeding seasons. The island is closed to visitors from October to March to protect seal pups and other wildlife.
