Donegal Bay by boat and by foot: the Waterbus and the Bank Walk

Donegal Town sits at the tidal head of Donegal Bay, and the two best ways to experience that setting are from the water and from the shore. The Donegal Bay Waterbus takes you out onto the bay itself; the Bank Walk keeps you on land but follows the River Eske along much of the same stretch of water. Between them they cover the town's harbour side properly, and they work well done on the same day, one after the other.

Donegal Bay Waterbus

The Waterbus is a 75-minute boat tour departing from the Pier in the town centre, taking in the Old Abbey ruins, Belles Isle, Donegal Castle seen from the water, the ruins at Magherabeg and a natural seal colony of around 200 animals. The boat carries up to 160 passengers, with full bar facilities and onboard entertainment on the return leg, so it is a genuinely social outing rather than a quiet nature cruise. It runs seasonally and is confirmed closed from November to February, so anyone visiting outside March to October should not plan a trip around it without checking the current timetable first.

Tickets are sold from the operator's office on Quay Street, next to Dom's Pier 1 Bar, rather than at the pier itself, so allow a few minutes to find the office before sailing time. Bring a layer even on a warm day ashore, since the bay can be breezy once you are out on the water, and the seal colony is close to a guaranteed sighting rather than a lucky one, which makes this a good outing with children.

The Bank Walk

The Bank Walk is the shore-side counterpart, a mostly level, tree-lined path along the south bank of the River Eske estuary, suitable for all abilities and free to walk at any time. The main route covers around 2.3km, of which roughly 900m runs directly alongside the river, with views across the water to the Old Abbey ruins, St Ernan's, Belle's Isle and Green Island, several of the same landmarks the Waterbus passes from the opposite direction. It can be extended into a longer loop of about 5km by continuing on to the L18451 local road and back into town via the N56, passing the Four Masters GAA club on the way.

What to expect underfoot

The path is mostly natural surface through woodland rather than fully paved, but it is buggy-friendly and has benches set at regular intervals, so it suits a range of paces and fitness levels. Songbirds, waders and other water birds are regularly seen along the tidal stretch, particularly on a falling or low tide when more of the shoreline is exposed, and squirrels are reported in the wooded sections. Dogs are allowed on leads. Parking at the start is free, which makes the walk an easy add-on to a castle or Diamond visit rather than something that needs a special trip.

Doing both in a day

If you only have one day to give the bay and the river properly, a workable order is: take the Waterbus first, in the early afternoon when the tour typically runs, to see the Abbey, the castle and the seals from the water. Then, later in the afternoon, walk the Bank Walk along the shore, taking in some of the same landmarks from land level and at your own pace, rather than from a moving boat. The two views of the same water, the estuary and the ruins, complement each other more than either does alone, and together they take up a comfortable half-day without feeling rushed.

Both are weather-dependent to some degree, the Waterbus more so since it is seasonal and on open water, so build in flexibility if you are visiting outside the main summer months, and always check current sailing times and the walk's extended-loop option against how much daylight and energy you have left.

When each one suits you best

If you only have time for one, let the weather and the tide decide. On a calm, bright morning the Waterbus is the better use of your time, since the bay is at its most photogenic and the seal colony is easiest to spot from open water. On a wet or windy day, the Bank Walk still works, since the woodland shelters much of the route and the path stays walkable in weather that would make an open boat unpleasant. Either way, both are free or low-cost enough that neither commits your whole day, which is part of why they pair so well with a castle visit or an afternoon around the Diamond.
