Dublin: Dublin Bay Cruise from Howth to Dun Laoghaire

Dublin Bay looks best from the water, and this one-way cruise from Howth to Dun Laoghaire gives you a fine coastal sampler without taking up half your day. The route passes Ireland’s Eye, Howth Head, Baily Lighthouse, Bull Island, Dalkey Island, and the harbor at Dun Laoghaire.

I like two things here: you can reach Howth by DART before sailing, and the cruise turns a simple rail trip into a scenic crossing. I also like the friendly onboard service, light commentary, and the option to buy a coffee or glass of wine while you watch the coast.

The main catch is practical: this is a one-way sailing, not a round trip. The open viewing area can feel tight when the sea gets choppy, so bring a jacket and be ready to spend part of the journey inside if needed.

Key points at a glance

• Sail aboard the St Bridget: The boat takes about 60 to 70 minutes to cross Dublin Bay.
• Start at Howth’s West Pier: Look for the departure point opposite Aqua Restaurant.
• See Ireland’s Eye and Lambay Island: These northern islands add early coastal scenery before the boat turns around Howth Head.
• Pass two important lighthouses: Baily Lighthouse sits near Howth Head, while Kish Lighthouse marks the bay farther offshore.
• Finish at Dun Laoghaire’s East Pier: You can enjoy food and drinks in town before taking the DART back.
• Expect a casual onboard experience: Coffee, wine, a bar, and commentary are available, but snacks and drinks cost extra.

Why this Dublin Bay cruise works well

The clever part of this excursion is its route. You are not simply going out to sea and returning to the same pier. You use the DART to reach Howth, board at the West Pier, cross the bay by boat, and finish in Dun Laoghaire. That makes the cruise both a sightseeing activity and a useful way to connect two of Dublin County’s best-known coastal towns.

At around an hour to 70 minutes, the sailing is long enough to give you changing views without demanding a full day. You get cliffs, islands, lighthouses, open water, wildlife habitat, and a harbor arrival in one short trip. For me, that is the strongest reason to book it.

The experience is also easy to understand. There is no complicated tour program or series of stops where you must keep checking the clock. You board at Howth, settle in, watch the bay unfold, and step off at Dun Laoghaire. If you want a relaxed outing with a clear start and finish, this format suits you well.

The boat is the St Bridget. On board, you can buy a coffee or a glass of wine, and there is commentary during the crossing. The atmosphere is informal rather than polished or formal, which fits a short harbor-and-coast cruise.

Getting to Howth’s West Pier

Your departure point is on the West Pier in Howth, opposite Aqua Restaurant. The simplest plan is to take the DART to Howth before the cruise. That approach makes good sense because Howth is already one of Dublin’s convenient coastal rail destinations, and you avoid arranging a separate taxi or transfer.

Give yourself enough time to find the pier and get settled. The precise sailing time depends on the date and availability, so check the departure schedule when booking rather than treating the cruise as a walk-up activity. Comfortable shoes and comfortable clothing are sensible choices, especially if you want to move between the inside and outside areas during the crossing.

Howth is a pleasant place to arrive early. The cruise itself is the focus, but the town gives you a chance to get a coffee, look around the harbor, or simply watch the fishing boats before boarding. Do not cut the timing too close. The West Pier is specific, and being in Howth is not the same as being at the departure point.

Ireland’s Eye and Lambay Island

Once the St Bridget leaves Howth, the first views open toward the islands north of the bay. Ireland’s Eye is close to Howth and gives the crossing an immediate sense of place. It is not just open water at the start, but a coastal route with islands, headlands, and working harbor scenery.

Lambay Island is farther north and adds another distant point to look for. On a clear day, these views help you understand Dublin Bay as a broad coastal setting rather than just a stretch of water between two suburbs. The commentary can help identify what you are seeing, but keep your eyes outside too. Some of the best moments are simple ones, such as watching Howth recede while the boat angles toward the open bay.

This is a good stretch for photographs, though conditions matter. Wind, cloud, and spray can change how long you want to remain outdoors. The boat gives you an indoor option, which is useful when the weather turns cool or the sea becomes uneven.

Howth Cliffs and the turn around Howth Head

The cruise then passes the Howth Cliffs and rounds Howth Head. From the water, the cliffs offer a different perspective from the walking paths above them. Instead of looking out over the bay from land, you look back at the headland as a single sweep of rocky coast.

That change in viewpoint is one of the best features of the trip. If you have already visited Howth on foot, the boat still gives you something new. If this is your first visit, the cruise provides a quick visual introduction to the headland without requiring a hike.

As the St Bridget passes the headland, watch for Baily Lighthouse. Its position near Howth Head makes it a clear marker along the route. The lighthouse is one of the details that gives the coast character, and the boat’s distance lets you see it in relation to the headland rather than as an isolated sight.

This is also where wind and waves may become more noticeable. One useful tip is to dress for the water, not merely for Dublin on land. A comfortable jacket will make the outdoor viewing area much more enjoyable, and steady shoes help when moving around the boat.

Baily Lighthouse, Kish Lighthouse, and Bull Island

Baily Lighthouse is followed by views toward Kish Lighthouse, farther across Dublin Bay. Seeing both in one short crossing gives you a good sense of how the bay is marked and navigated. The lighthouses also break up the open-water portion of the trip, giving you particular points to watch for rather than a continuous stretch of sea.

The route then passes by Bull Island, a well-known wildlife sanctuary. The boat does not turn this into a wildlife tour, so you should not expect a dedicated animal-spotting program. Still, the island adds another kind of scenery to the cruise, shifting the view from cliffs and lighthouse structures to a lower, more open coastal setting.

The bay can be calm, but it can also be choppy. One practical limitation is the size of the outdoor viewing space. When conditions are rough or many people want the same viewpoint, you may spend part of the crossing inside. That does not ruin the trip, but it is worth knowing if your main goal is to stand outside for the entire 70 minutes.

I would treat the cruise as a flexible viewing experience. Move outside when the view is best, then come inside for a while if the wind picks up. You can still follow the route through the windows and commentary, and you will be more comfortable by the time the boat reaches the southern side of the bay.

Dalkey Island and arrival at Dun Laoghaire

As the St Bridget crosses toward the south side of Dublin Bay, Dalkey Island comes into view. It is a fitting late highlight because the scenery changes again. The northern part of the journey centers on Howth Head and its cliffs, while the approach to Dun Laoghaire brings a more settled harbor setting.

The final approach takes you into Dun Laoghaire Harbour, with the cruise ending at the East Pier. Arriving by water makes the destination feel different from simply reaching it by train. You have watched the town grow closer from the bay, then entered through its harbor rather than arriving along a city street.

The activity does not include a return sailing. That point matters when planning your day. You can use the DART to return, and a discount voucher for the return journey is included. The rail option keeps the trip practical and means you do not have to retrace the crossing by boat.

Dun Laoghaire is a good place to continue your afternoon. You can find food and drinks after getting off the boat, as one useful plan is to make the cruise the middle part of a coastal day: DART to Howth, boat to Dun Laoghaire, then a meal and DART back.

What the onboard experience is really like

The St Bridget offers a casual setting rather than a luxury yacht experience. You can buy drinks on board, including coffee or wine, while commentary helps point out parts of the route. Snacks and drinks are not included in the ticket price, so budget a little extra if you want something during the crossing.

The friendly service is an important part of the experience. The captain has been praised for being funny and welcoming, and the onboard service has a warm, relaxed feel. There is no captain’s name provided, so I would not expect a named guide-led tour. This is a boat trip with commentary rather than a private guiding experience.

The rating of 4.3 from 44 reviews reflects that balance. The views and the good-humored crew receive the strongest praise, while the main reservation concerns limited outdoor space in choppy conditions. That is a fair picture of what you are buying: a pleasant coastal crossing with sightseeing value, not an elaborate cruise ship outing.

Families can use the trip easily because it is suitable for all ages and infants. The short duration helps if you are planning around children or simply want a manageable activity between other plans. Still, keep clothing and sea conditions in mind. Even a short crossing can feel cool and windy.

Is $28 a fair price?

At $28 per person, the value depends on how you use the route. If you only want transportation between Howth and Dun Laoghaire, the ticket costs more than a simple rail journey. But this is not just transport. You are paying for a scenic crossing past islands, cliffs, lighthouses, Bull Island, Dalkey Island, and Dun Laoghaire Harbour.

The price looks stronger when you combine it with a full coastal outing. Take the DART to Howth, allow time near the harbor, board the St Bridget, then spend time in Dun Laoghaire before using the return discount voucher. You get a distinct way to see the bay and avoid making the whole day another train ride.

It is less compelling if you want a long cruise with extensive facilities or a guaranteed outdoor viewing deck. Drinks and snacks cost extra, and the sailing is short. I would book it for the route and the change of perspective, not for onboard dining or luxury.

The included DART discount voucher improves the practical value. It does not turn the experience into a bargain for every person, but it helps with the return plan and makes the one-way format easier to manage.

Who should book this sailing?

I would recommend it to you if you want a scenic activity that fits neatly into a Dublin day. It suits couples, families, friends, and solo visitors who enjoy coastal views but do not want a demanding walk or a full-day boat tour.

It is especially useful if you already plan to visit Howth or Dun Laoghaire. Rather than treating both places as separate outings, you can connect them by water and make the journey itself part of the day.

You should also consider it if you enjoy seeing familiar places from a new angle. The cruise gives you views of Howth Head, Baily Lighthouse, and Dalkey Island that you cannot get from the DART. The short duration leaves plenty of time for lunch, a walk, or other Dublin plans.

I would be more cautious if motion bothers you or if you need a large outdoor deck. The sea may be choppy, and the outdoor area can feel crowded. In that case, check the forecast and keep your expectations modest. The trip remains worthwhile for the scenery, but it may not deliver continuous open-air viewing.

Practical tips for a smoother trip

• Arrive at the correct pier: Departure is from the West Pier in Howth, opposite Aqua Restaurant.
• Use the DART for the first leg: Taking the train to Howth is part of the most practical plan.
• Wear comfortable clothes and shoes: You may move between indoor and outdoor areas, and the pier can be breezy.
• Bring a light extra layer: Dublin Bay weather can feel cooler on the water than on land.
• Plan for one-way travel: The boat finishes at Dun Laoghaire’s East Pier. Use the DART for your return.
• Allow extra time in Dun Laoghaire: The harbor area gives you an easy place to eat or have a drink after the cruise.
• Keep some money for the bar: Coffee and wine are available, but drinks and snacks are not included.
• Check times before setting out: Sailings last about 60 to 70 minutes, with departure times dependent on availability.

Free cancellation is available up to 24 hours before departure, and you can reserve now and pay later. Those options are useful if your Dublin plans may shift, but the more important planning detail is still the one-way route and the return by DART.
