A Mill Pond Taken Back by Nature

From any of the gates off the estate track it is hard to believe that this 26.8-hectare basin was built by hand. The landowners of 18th-century Islay raised a dam to back up the River Drolsay and feed waterwheels at the estate mills — and later the long-gone Newton Distillery at Newton House. Once the machinery fell silent, the loch settled into its own ecology: drained gently to the southwest by the Eallabus Burn, ringed by trees and quietly handed over to reed, water-bird and otter.↗↗

The technical picture matches the gentle character of the place. UK Lakes Portal describes a small, shallow, low-altitude loch sitting at 25 metres above the sea, with an average depth of about five metres, a three-kilometre shoreline and a catchment more than twenty times the size of the water itself. Mildly alkaline, peat-stained and only a stone's throw from the coast, that is exactly the kind of water the island's wintering geese and swans prefer.↗

The loch also supports a recreational fishery, so on a still morning you are likely to share the shore with a couple of quiet anglers as well as the birds.↗

Walking the Shore

The classic outing is a circular walk that joins the loch with the higher ground at Knockdon, starting from Bridgend Woods car park. The full loop is around 7 km (about 4.5 miles) and takes roughly two hours at an easy pace, with a much shorter pushchair-friendly version available by following the access road past Eallabus House straight back to the car park.↗

On the longer route, take the roadside path uphill towards Newton, then follow the single-track road past New Houses. A gateway to Eallabus House appears on the left, and diagonally opposite it a softer track peels down to the water. That detour is the heart of the walk — a muddier, more atmospheric loop that hugs the shoreline, with otters working the shallows and wildfowl scattered across the open water and the reed-beds.↗

If you keep going, the route passes the farmhouse at Knockdon and climbs gently onto farm tracks behind East Cararbus, opening out lovely views across Loch Indaal as the land rises. Because cattle graze the fields around the loch all year, the full circuit is unsuitable for dogs; the shorter version is fine on a lead.↗

Wildfowl: Why Winter Is the Moment to Come

Loch Skerrols is one of Islay's quietly important wildfowl sites, and the autumn passage is when the loch fills up. Islay Natural History Trust watchers have logged around 500 wigeon resting on the water alongside the resident greylag geese, with smaller numbers of other ducks in the shallows.↗

The loch is also a staging post for whooper swans moving down the North Atlantic flyway towards their wintering grounds in Ireland. In a good year the count can pass 130 birds at once, drifting between open water and surrounding fields with a striking number of this year's cygnets among them, the resident mute swans apparently tolerating the newcomers surprisingly well.↗

Just beyond the shoreline, the fields around Octovullin often carry Greenland white-fronted geese, Islay's signature winter visitor, so binoculars earn their place here. Even the waterline has its oddities: in 2011 a river snail, almost certainly a new record for Scotland, was first found on Islay right here in Loch Skerrols.↗

Seeing It with Local Naturalists

If you would rather not hunt for the tracks yourself, the Islay Natural History Trust has run a Loch Skerrols Stroll through the woods for ducks and other wildlife, meeting at Islay House Square car park in Bridgend. It is a low-key, family-friendly way to get an introduction to the loch and the island's birdlife, and the Trust can tell you whether a walk is scheduled during your visit.↗

Visiting in Practice

Loch Skerrols lies about a mile north-northeast of Bridgend, roughly in the middle of Islay's north-central belt between Port Ellen and Port Charlotte, and is reached entirely on foot from the estate and farm tracks around the village. The shoreline path is unsurfaced and soft underfoot in all seasons, with wetter patches closer to the reeds — proper walking boots are worth putting on even on a dry morning, and there is no formal visitor centre, so bring water and (for birders) a spare camera battery.↗↗

Because the site is a working recreational fishery and an important wintering area, move gently along the shore, give the flocks a wide berth when the loch is crowded with high-tide birds, and leave farm gates as you find them. The nearby wildlife sites of Loch Gruinart and Loch Indaal make an easy pairing for a longer island birding afternoon.↗↗
