Why Thousands of Puffins Return to Scotland Every May — and Where to See Them

Every April, something remarkable happens on Scotland’s sea cliffs. After months far out in the North Atlantic, hundreds of thousands of small black-and-white birds return to the same grassy burrows they left the previous summer. The Atlantic puffin is back — and if you time it right, you can be there when they arrive.

Scotland hosts around 90% of Britain’s breeding puffins — roughly 350,000 pairs, scattered across dozens of islands and sea stacks from the Firth of Forth to the far north. They’re here for five months. Then, as quietly as they arrived, they vanish back to sea.

Here’s where to find them, and why May is the best month to try.

Why Puffins Come Back to Scotland Every Year

Puffins spend the winter far offshore, riding Atlantic swells and diving for fish. But every spring, an ancient instinct pulls them back to land. Scotland’s rocky islands offer exactly what they need: soft turf to burrow into, fish-rich waters close by, and enough height to launch themselves into the air.

The breeding season runs from late April through August. By May, colonies are fully active — pairs greeting each other at burrow entrances, birds arriving laden with sand eels, and pufflings growing quietly underground. A puffin may return to the same burrow for over twenty years.

Getting the timing right matters. Most colonies are at their liveliest in May and June. By late July, things quiet down as birds prepare to leave again.

Scotland’s Best Puffin Colonies

Not all puffin sites are equal. Some are accessible on a day trip; others require planning. These four are the most rewarding — and between them, they cover the length of the country.

Isle of May, Firth of Forth

The Isle of May sits at the mouth of the Firth of Forth, about 50 kilometres east of Edinburgh. It hosts one of Scotland’s largest colonies — up to 100,000 puffins in peak season. Boat trips leave from Anstruther in Fife from May through July, taking around 45 minutes each way.

Puffins on the Isle of May are famously relaxed around people. You can sit on the grass and watch them land just metres away, bills full of sand eels. The island also supports grey seals, razorbills, guillemots, and shags — a full day of wildlife watching within easy reach of the capital.

Staffa and the Treshnish Isles, off Mull

Off the west coast of Mull, the flat-topped island of Lunga on the Treshnish Isles holds up to 2,000 breeding puffins. They nest in the clifftop turf and barely glance at visitors. Combined boat trips from Fionnphort or Iona also stop at Staffa — the volcanic island of hexagonal basalt columns and the thundering cavern of Fingal’s Cave.

Seeing both in one day — one geological wonder, one wildlife spectacle — makes this one of Scotland’s great excursions. Book ahead: June and July trips sell out weeks in advance. If you’re making the journey, our guide to the Isle of Mull will help you plan the wider trip.

Handa Island, Sutherland

Few visitors make it to Handa Island. That’s exactly why it’s worth the effort. This small island off the northwest coast, near Scourie in Sutherland, holds around 200,000 seabirds on its towering sea stacks — puffins, guillemots, razorbills, and the aggressive great skua all breed here.

A short passenger ferry from the village of Tarbet brings you to the island, managed as a wildlife reserve by the Scottish Wildlife Trust. There are no facilities, no crowds, and no noise beyond the wind and the birds. If you’re driving the North Coast 500, Handa is a natural stop along the route.

Bass Rock, North Berwick

Bass Rock rises from the Firth of Forth just off the East Lothian coast. It’s best known as the world’s largest northern gannet colony — around 150,000 birds — but puffins nest here too. In summer, the rock turns white with birds.

Boat trips depart from North Berwick harbour from April through September. Some circle the rock; others allow you to step ashore. Both are spectacular. We’ve got a full guide to Bass Rock and the North Berwick coast if you want to build a full day around it.

When to Go and What to Expect

May is the sweet spot. Colonies are fully active, the seas are calmer than winter, and the summer crowds haven’t yet arrived. Most boat operators open in late April and run through July or early August.

Puffins leave their colonies by mid-August — sometimes earlier if breeding finishes ahead of schedule. After that, the cliffs fall quiet until the following spring.

Bring binoculars. Even on warm days, wind on Scottish islands can be brisk. Waterproofs are wise whatever the forecast. For the best overall picture of when to visit Scotland through the seasons, our month-by-month guide covers everything from wildlife to festivals.

When is the best time to see puffins in Scotland?

Late April through July is the core puffin season. May and June offer the best combination of active colonies, reasonable weather, and available boat trips. Most puffins leave Scotland’s coasts by mid-August.

Where is the easiest place to see puffins in Scotland?

The Isle of May in the Firth of Forth is the most accessible colony, with regular boat trips from Anstruther in Fife. It’s within easy day-trip distance of Edinburgh and St Andrews.

Do you need to book puffin boat trips in advance?

Yes — especially in June and July. Popular trips to Staffa, Lunga, the Isle of May, and Bass Rock sell out weeks ahead. Book as soon as your travel dates are confirmed.

Can you see puffins on the Scottish mainland?

Small numbers of puffins nest on a few mainland cliffs, but island colonies are far more impressive. Sumburgh Head in Shetland is also an accessible option if you’re already travelling north.

There’s something unexpectedly moving about watching a puffin land from the sea. It has made this same journey — from somewhere in the wild North Atlantic, back to this same burrow — perhaps twenty times. Scotland’s islands are their home. In May, if you’re willing to take a short boat trip, they’ll let you share it with them.
