Wildlife & Nature on Islay

Over 30,000 barnacle geese arrive from Greenland each October, spending winter on Islay before returning north in April. RSPB Loch Gruinart reserve is the best viewing location — the morning flights as thousands of geese lift from the loch are spectacular. The sound is unforgettable.

If you're visiting between October and April, witnessing the geese is a highlight. Arrive at Loch Gruinart at dawn for the best show. Guests who've experienced this consistently describe it as one of their trip highlights. The local farmers, however, are a bit less enthusiastic — they can decimate crops!

Islay has both golden eagles and white-tailed sea eagles — two of Scotland's most magnificent raptors. Keep an eye out for them over moorland, coastal cliffs, and inland hills. Sea eagles are enormous with wingspans up to 8 feet. If you see something huge gliding overhead, it's likely a sea eagle. A good check is "does it look like a barn door?" — their square-ended wing profile is quite distinctive.

We keep binoculars in all our properties, and guests regularly spot eagles from the houses or during coastal walks.

Common seals and grey seals frequent Loch Indaal and coastal areas. Guests spot seals from our property windows regularly — sometimes they're visible from the breakfast table at Portbahn House. Otters are shyer but present along quiet shorelines. Your best chance is early morning or dusk along the coast. Meandering along the stretch of coast that runs alongside the Bruichladdich–Port Charlotte cycle path is a lovely way to wildlife spot.

Dolphins and porpoises also occasionally visit Loch Indaal. We've had guests see them from Portbahn House and Shorefield's windows — it's rare but magical when it happens. Minke whales and basking sharks can sometimes be seen offshore in summer months.

• RSPB Loch Gruinart — Flagship reserve for geese, waders, raptors. Also has a nature trail and woods to explore.
• RSPB The Oa — Cliffs, choughs, seabirds, dramatic coastal scenery.

Both reserves are free to visit with hides, trails, and visitor information. Bring binoculars (essential for birding), a camera with zoom lens, and warm layers for dawn/dusk watching.

Islay's wildlife calendar has distinct seasons, and timing your trip around one or two target species transforms the experience.

October to April (winter) is the standout season for birdwatchers. The barnacle geese arrive from Greenland in October, and at their peak there are over 30,000 at Loch Gruinart — the morning flight at dawn, when thousands lift off the loch simultaneously, is one of the most extraordinary wildlife spectacles in Britain. The sound carries for miles. This is also the best time for waders, wildfowl, and raptors on the reserve. Winter light on the Rhinns is often extraordinary — low, long, and golden even on clear days.

May to September (summer) offers different wildlife but equally rich. Basking sharks patrol the waters around the Mull of Oa and Rinns Point — Islay is one of the better spots in Scotland for seeing them from headlands in calm conditions. Minke whales occasionally appear in the Sound of Islay between June and August. Seabirds nest on the coastal cliffs at The Oa through summer; this is the best time to see choughs, one of the UK's rarest corvids, on the clifftop walks there. Sea eagles breed on Islay and can be seen year-round, but are more actively hunting over coastal areas in summer.

Year-round: both eagle species, grey and common seals, occasional otters, and year-round birdwatching at Loch Gruinart and the coastal paths.

RSPB Loch Gruinart reserve is 20 minutes' drive from our Bruichladdich properties, accessed via the B8018 road through Kilchoman. The reserve has two hides and an information centre. The best viewing is at dawn, when the geese lift from their overnight roost on the loch — arrive before first light and wait in the hide. The experience is as much about sound as sight: the noise of 30,000 birds building to take flight, and then the overwhelming rush of wings, is unlike anything else.

Peak numbers are typically November and December. By March the geese are preparing to leave; by April they're gone. The reserve is free to visit; parking and hides are at the end of the reserve road. If you're coming in winter, dress for cold and damp — binoculars with good low-light performance make a significant difference at dawn.

RSPB Loch Gruinart is also, separately, an oyster farm — one of the finest in Scotland, farming in the cold, clean tidal waters of the loch. Combining a dawn geese watch with fresh oysters later in the morning is one of the best day-out combinations on the island. See the food and drink guide for the Loch Gruinart Oyster Shack details.

Islay's otters are shy and elusive, but they are there. The best chance is along sheltered shorelines — the Bruichladdich to Port Charlotte coastal path runs along exactly the right kind of terrain, with rocky outcrops, seaweed beds, and shallow water where otters feed. Early morning and dusk are the productive times: an otter moving along the shore, turning rocks or diving briefly, can be spotted by a careful eye if you walk slowly and scan ahead rather than just watching your feet.

Loch Gruinart's shoreline and the quieter stretches of the Rhinns coastline around Portnahaven are also good. The Corryvreckan channel between Jura and Scarba (accessible on a day trip to Jura) holds otters, though the primary attraction there is the whirlpool itself.

Patience is the essential kit. Binoculars help. If you're actively looking for otters, plan a slow two-hour coastal walk rather than a brisk one.

The Mull of Oa is Islay's dramatic southern headland — cliff-lined, exposed, and atmospheric in any weather. The RSPB The Oa reserve here protects cliffs, coastal heath, and the best chough population on Islay. Choughs are red-billed, red-legged members of the crow family — acrobatic fliers, particularly visible in pairs or small groups along the cliff edges. Islay is one of the most reliable places in Scotland to see them.

The Oa also has a striking landmark: the American Monument on the headland cliff, commemorating the loss of American troops aboard the troopships HMS Tuscania and HMS Otranto, both sunk off the Oa in 1918. The monument, the coastal walk to reach it, and the dramatic views to the Antrim coast of Ireland on clear days make this one of Islay's most rewarding half-day excursions — the wildlife is a bonus to the landscape.

Shorefield Eco House is our wildlife property — the Jacksons built it specifically around a love of birds and nature. They created wetland ponds, planted the woodland that now surrounds the house, and installed bird hides in the garden. The binoculars and bird books in the house are from their personal collection. Guests who prioritise wildlife consistently gravitate toward Shorefield: it offers passive wildlife watching from the windows — waterfowl, seabirds, and garden birds without leaving the property — alongside the active wildlife experiences available across the island. View Shorefield Eco House.

The coastal paths around Islay — particularly the Bruichladdich to Port Charlotte cycle path — are excellent for wildlife watching as well as swimming. See the beaches guide for safe swimming spots, Portbahn Beach access, and Machir Bay coastal walks.
