Dublin: Dublin Bay Cruise from Dun Laoghaire to Howth

Dublin Bay looks entirely different from the water. Aboard the St Bridget, you sail from Dun Laoghaire past islands, Martello towers, the Baily Lighthouse, and the Dublin Mountains before arriving at Howth Harbor. It is a simple way to connect two fine coastal towns without retracing your steps by road.

I like the fresh view of Dublin and the chance to see seals near Howth. I also like the flexible return: you can spend time in Howth, eat seafood, walk the harbor, and use the discounted DART trip afterward. The main catch is the weather. Wind and rain can make the upper deck uncomfortable, and the onboard commentary may be hard to hear from downstairs.

Key points to know before you book

• A one-way coastal crossing: The boat runs from Dun Laoghaire’s East Pier to Howth’s West Pier in about 60 to 70 minutes.
• Best views upstairs: The upper deck gives you the clearest sight lines and the best chance for photos, but bring a jacket.
• Howth seals: Keep watch as you approach Howth Harbor, where seals often swim near the boats.
• A useful return option: A discounted DART voucher is included, so you can return to Dun Laoghaire by train after exploring Howth.
• Good for families: All ages can join, and children under three ride free.
• Friendly onboard service: Eugene is especially helpful with local suggestions, including a recommendation for chowder at The Brass Monkey in Howth.

From Dun Laoghaire’s East Pier to open water

The trip begins at the East Pier in Dun Laoghaire, just before the Bandstand. This is a pleasant starting point in its own right, with the long pier giving you a chance to look across the bay before boarding.

The sailing is one way, not a loop. That matters when you plan your day. You can arrive in Dun Laoghaire, take the boat to Howth, and then make Howth your next stop rather than returning immediately to the original pier. A discounted DART voucher is included for the journey afterward, which makes the cruise useful as transport as well as sightseeing.

Once the St Bridget leaves the pier, the pace is relaxed. You are not racing from one attraction to another. The boat gives you time to watch the shoreline change, with Dun Laoghaire’s harbor giving way to open views across Dublin Bay.

The boat has more than one deck, with indoor seating below and outdoor viewing areas above. If the weather is dry and calm, I would head upstairs early. You will get a wider view, better photos, and a clearer look at the islands and headlands. If wind or rain moves in, the covered lower deck gives you shelter while still allowing you to look out through the windows.

The Dublin Mountains from the bay

One of the strongest reasons to take this trip is the change in perspective. From land, Dublin’s mountains sit behind the city. From the bay, they form a long backdrop to the shoreline, and the city feels more open and spread out.

The exact view depends on the weather. On a clear day, the mountains help frame the bay and give your photos some depth. On a gray day, the mood is more subdued, but the boat ride still provides a calm break from busy city streets.

The bay also shows you parts of Dublin that are difficult to connect when you are moving around by car or train. You see the coast as a whole rather than as separate stops. The water links Dun Laoghaire, Dalkey, Howth, Bull Island, and the offshore islands into one broad scene.

This is not a boat with a packed schedule of formal stops. You stay aboard for the crossing, so the value comes from the view, the fresh air, and the simple pleasure of letting the city slide past.

Dalkey Island, Martello towers, and the Baily Lighthouse

The cruise passes several of Dublin Bay’s most recognizable coastal sights. Dalkey Island is one of the most interesting, especially when the weather gives you a clear view of its rocky outline. Ireland’s Eye and Lambay Island add more offshore scenery as you continue toward Howth.

You may also spot Joyce’s Martello Tower. The tower is tied to the coastal defenses that once watched over Dublin Bay, but you do not need to be a history specialist to enjoy seeing it from the water. It is a striking marker on the coast and gives the voyage a sense of place.

The Baily Lighthouse is another highlight. Positioned on the Howth Head area, it helps you understand just how far the boat has traveled along the bay. Approaching from the water gives the lighthouse a different character than seeing it from a road or walking path.

The onboard commentary includes stories and myths about the places you pass. It adds useful context, although the sound system is not equally clear everywhere on the boat. You may find the commentary difficult to follow from the lower deck, particularly when the weather keeps everyone indoors. If hearing the stories matters to you, sit upstairs or as close to the audio source as you can.

Bull Island and the bay’s wildlife

Bull Island is another feature to watch for during the crossing. The island and surrounding area are known for wildlife, and the view helps explain why this part of Dublin Bay has such a strong natural character despite its closeness to the capital.

Do not treat the wildlife sightings as guaranteed. A seal may appear, and one sailing even produced a glimpse of dolphins, but nature does not follow the timetable. The cruise is worthwhile without seeing animals, with the wildlife serving as a welcome extra.

The most reliable seal-watching opportunity comes near Howth Harbor. As the boat approaches, look toward the water around the harbor and moored boats. Seals are often seen swimming nearby, sometimes lingering long enough for photographs.

Bring patience and keep your phone or camera ready, but do not spend the whole crossing staring through a screen. The islands, cliffs, boats, and changing shoreline are the main event.

Arriving at Howth Harbor

The approach to Howth is the most scenic part for many passengers. The village has a working harbor, fishing boats, restaurants, and access to well-known coastal walks. From the water, you see Howth as a compact seaside community backed by the headland.

The cruise finishes at Howth’s West Pier. This puts you close to the harbor atmosphere and the places you are likely to want next. You can look for seals, find a meal, or set off on one of Howth’s walks before taking the DART onward.

Howth is particularly good as the second half of the day because the boat ride does not require you to rush straight back. The included DART discount gives you freedom to stay longer. You can make a relaxed harbor visit, stop for seafood, or spend more time outdoors if conditions are pleasant.

A useful local food tip came from Eugene, a friendly member of the crew, who recommended The Brass Monkey for chowder. That kind of practical suggestion can save you from choosing at random when you arrive hungry.

Weather, seating, and comfort on the St Bridget

You should dress for the water, not just for the forecast in central Dublin. A comfortable jacket is the most useful item to bring, even on a bright day. Wind can make the upper deck feel much colder than the pier, and the crossing may be bumpy at times.

The boat has indoor space below, which matters when rain begins or the wind picks up. Sitting downstairs keeps you dry, but the commentary may be harder to hear there, and the windows do not provide the same broad view as the open deck.

On a calm, sunny day, the trip can feel remarkably smooth. On another day, you will feel the movement of the boat. That is normal for a sea crossing, but anyone prone to motion sickness should plan accordingly and choose a steady seat below if needed.

Comfortable shoes are a sensible choice. You are not required to take a long walk during the sailing, but the piers and Howth itself are best enjoyed on foot. Comfortable clothing also makes it easier to adjust when the temperature changes.

The crew receives strong praise for being pleasant and helpful. Eugene, in particular, is remembered for assisting passengers and offering a good Howth food recommendation. A friendly crew matters on a short trip because it makes boarding, seating, and arrival feel easy rather than rushed.

Is the $32 price good value?

At $32 per person, this is not the cheapest way to move between Dun Laoghaire and Howth. A train journey is generally the practical choice if your only goal is to get from one place to the other.

The cruise earns its price by turning the transfer into a sightseeing experience. For about an hour, you get open-water views, coastal landmarks, islands, wildlife opportunities, and a different understanding of Dublin Bay. The discounted DART trip also reduces the cost of making your way back after spending time in Howth.

I think the value is strongest when you already want to visit both coastal towns. Instead of paying for a separate scenic boat ride and then arranging transport, you use the ferry as the scenic part of your day. It works especially well for a flexible itinerary with time for lunch or a walk in Howth.

The value is weaker if your schedule is tight or the weather looks poor. In heavy rain or strong wind, you may spend much of the crossing indoors, and the views will not have the same appeal. You can cancel up to 24 hours in advance for a full refund, which is useful when Dublin’s forecast changes.

You can also reserve now and pay later, allowing you to hold a place without paying at once. That is helpful for a trip where the weather plays such a large role.

Who will enjoy this cruise most?

I would recommend the trip to anyone who wants to see Dublin from a different angle without committing to a long excursion. It suits couples, families, older visitors, and solo passengers who enjoy a quiet hour on the water.

Children should find the boat ride easy to manage, and those under three can join free. The combination of a boat journey, islands, seals, and a fishing harbor gives younger passengers plenty to watch without requiring a full day of sightseeing.

It also works well for local residents. You do not need to be visiting Dublin for the first time to appreciate the bay from the water. The scenery changes with the light, the weather, and the boats on the bay, so this can be a pleasant day out rather than a tourist-only activity.

Dog owners should confirm the current boarding rules before booking. A dog named Murphy was welcomed aboard and became popular with other passengers, but the supplied information does not set out a formal pet policy.

The cruise may be less suitable if you dislike open water, need a completely smooth ride, or want detailed commentary throughout the journey. The audio can be difficult to hear below deck, and the sea can be bumpy.

How to plan your day around the sailing

Allow time to reach Dun Laoghaire’s East Pier before departure. The meeting point is just before the Bandstand, and arriving early gives you a better chance of choosing an upper-deck place if conditions are good.

Keep the schedule after arrival flexible. The sailing takes about 60 to 70 minutes, but you will want time in Howth rather than treating the harbor as a quick drop-off point. A seafood meal, a look around the harbor, or one of the local walks can turn the crossing into a fuller day.

The return DART option is one of the most useful details. You do not need to book a return ferry as part of the basic one-way trip, although a return ferry can be arranged when boarding if you prefer that option. The DART lets you set your own pace in Howth and return by rail afterward.

If you plan to eat in Howth, keep your arrival time in mind. The cruise is short, but your total day will depend on how long you stay in the village and what you choose to do after stepping off the boat.

Should you book the Dun Laoghaire to Howth cruise?

Book it if you want a scenic connection between two Dublin coastal towns, enjoy being outdoors, and can accept that Irish weather may affect the experience. The views of Dalkey Island, Ireland’s Eye, Lambay Island, Bull Island, the Martello tower, and the Baily Lighthouse give the hour real sightseeing value.

I would be especially happy to book it on a reasonably bright day, with a jacket packed and enough time to explore Howth afterward. Sit upstairs for the clearest views, move below if the weather turns, and watch the harbor carefully for seals.

Skip it if you only need the fastest or cheapest transport, or if the forecast suggests conditions that will keep you indoors for the whole crossing. For everyone else, this is a pleasant way to make Dublin Bay part of your day rather than simply passing around it.
