Dublin: Dublin Bay Cruise from Dun Laoghaire to Howth

Dublin Bay looks entirely different from the water. From the St Bridget, you glide past Martello towers, islands, lighthouses, sailing boats, and the long curve of the coast before arriving at Howth. I like the gentle sense of travel here: this is both a scenic cruise and a useful one-way trip between two of Dublin’s best seaside towns.

I especially like the wide views from the upper deck and the chance to spot seals near Howth Harbor. The friendly crew add to the outing, with Eugene singled out for helpful restaurant advice. The main drawback is simple: the Irish weather can make the open deck cold and windy, while the onboard commentary may be hard to hear from downstairs.

Key points to know before sailing

• St Bridget crosses Dublin Bay in 60 to 70 minutes, giving you a scenic ride rather than a short harbor loop.
• Dun Laoghaire’s East Pier is the departure point, just before the Bandstand.
• Howth is the destination, with fish restaurants, coastal walks, and seals often visible around the harbor.
• The upper deck offers the best views and photos, but bring a jacket because conditions can change quickly.
• A discounted DART voucher is included, making the train a practical way back to Dun Laoghaire.
• Children under three travel free, and the cruise suits all ages.

Why a boat is the best way to see Dublin Bay

Dublin Bay is easy to admire from roads and trains, but a boat gives you a much broader view. On land, the city often blocks the relationship between the coast, the mountains, and the islands. From the water, you can look back toward the Dublin Mountains while also watching the shoreline unfold in both directions.

This is not a sightseeing trip packed with stops. The attraction is the movement itself. You settle in, watch Dun Laoghaire recede, and gradually see the coastline change from harbor walls to open water and rocky headlands. The trip offers a different angle on places you may already have visited by foot.

The route also helps you connect two distinct coastal areas without retracing your steps by road. Dun Laoghaire feels like a grand harbor town with its long piers and open waterfront. Howth has a more traditional fishing-village character, with boats, seafood restaurants, and walks around the headland. The cruise makes the journey between them part of the day rather than dead time.

At about an hour, the crossing is long enough to feel like a proper excursion but short enough to fit into a busy Dublin schedule. I would allow extra time around the sailing if you want lunch, a walk in Howth, or a relaxed look around Dun Laoghaire before departure.

Starting at Dun Laoghaire’s East Pier

The boat leaves from the East Pier in Dun Laoghaire, just before the Bandstand. That is a pleasant place to begin, with open views across the harbor and plenty of room to get your bearings before boarding.

The departure area matters because the harbor has more than one pier. Check that you are heading for the East Pier, not the West Pier, and arrive with enough time to find the boarding point without rushing. The end of the trip is listed at Howth’s West Pier, so the journey takes you from one harbor setting to another.

Dun Laoghaire itself is worth treating as more than a transport point. The pier gives you a strong first look at the bay, and the scale of the harbor helps explain why the boat trip feels more substantial than a quick local ferry ride. You can begin outdoors, then choose your position on the boat according to the weather.

Riding the St Bridget across the bay

The St Bridget is the heart of the experience. You get a one-way ferry trip, with seating and viewing areas that allow you to move between sheltered and open positions. On a fine day, the upper deck is the obvious choice for photographs and uninterrupted views.

The open deck can also be chilly. Even when the sun is out, wind over the bay makes a jacket or warm layer useful. Comfortable clothing and shoes are sensible, especially if you plan to continue walking around Howth after arrival.

If the weather turns wet, the lower area provides shelter and window views. That is a real advantage on a changeable Dublin day. The tradeoff is that the recorded commentary may be difficult to hear downstairs. If you want to follow the information about the places you pass, try to sit upstairs when conditions allow, or move outside when the boat reaches a point of interest.

The ride may be smooth, but you should expect some movement. A boat is still a boat, and the crossing can become bumpy in wind. Most people will find the journey easy, though anyone sensitive to motion should choose a steady seat and keep the horizon in view.

The sights between Dun Laoghaire and Howth

The route packs a good deal of Dublin Bay into one hour. The scenery is not presented as a series of formal stops, so keep your camera ready and pay attention to the changing views.

You may see:

• The Dublin Mountains, rising behind the southern side of the bay
• Dalkey Island and Ireland’s Eye
• Lambay Island farther out
• Joyce’s Martello Tower
• The Baily Lighthouse
• Bull Island, a protected wildlife area
• The harbor and headland around Howth

Dalkey Island gives the southern part of the crossing a memorable offshore landmark. Ireland’s Eye provides another strong coastal view as the boat approaches Howth, while Lambay Island adds a sense of the wider waters beyond the city.

Joyce’s Martello Tower connects the trip to Dublin’s coastal defenses and literary associations. The Baily Lighthouse is one of the most striking sights on the approach to Howth. Seen from the water, its position on the headland makes more sense than it does on a map.

Bull Island is another highlight. From the boat, you can appreciate its broad sweep and its importance as a wildlife reserve. This is one of the places where the cruise gives you something a road trip cannot: a clear view of the island’s shape and position within the bay.

The onboard information adds context through stories, myths, and descriptions of the coastline. It is not the same as a private guide speaking directly to your group, and the sound can be weak in the sheltered area, but it gives the crossing more substance than a silent ferry ride.

Arriving at Howth Harbor

The approach to Howth is one of the best parts of the trip. The harbor, headland, lighthouse, and boats come into view gradually, giving you time to watch the coast from the water before stepping ashore.

Howth is a useful destination because you can shape the rest of your day around your interests. You might stop for seafood, walk along the waterfront, or set off on one of the area’s fantastic coastal walks. The cruise itself does not include a guided walk or meal, so those parts are up to you.

Keep an eye on the water around the harbor. Seals are a noted feature here, and they may swim near the boats. Sightings are never something to count on, but the possibility gives children and wildlife fans another reason to watch the shoreline instead of staying focused only on the bigger views.

The village is also where the one-way format makes sense. You are not simply returning to the place you started. You can spend time in Howth and later use the DART, with a discounted trip voucher supplied after the sailing. That creates a simple coastal day out without requiring a taxi or a second ferry booking.

Returning by DART or ferry

The cruise is sold as a one-way trip. The included discounted DART voucher is a practical touch, particularly if you want to enjoy Howth at your own pace and return to Dun Laoghaire later.

The train option also gives you a change of scenery. You see the bay from the water on the way out, then use the rail line for the return. This works well for a full day because you are free to choose how long to stay in Howth rather than working around a return sailing.

A return ferry can be booked when boarding, according to the supplied information. If you prefer the boat experience in both directions, ask about that option before setting off. The return journey may offer different views depending on the light and weather, but it also means committing more time to the water.

One detail needs care when planning: the activity description places the finish at Howth’s West Pier, while the general meeting information refers to returning to the meeting point. For a straightforward plan, treat this as a one-way sailing to Howth and confirm the precise disembarkation details when you board.

Price and overall value at $32

At $32 per person, this is not the cheapest way to move between Dun Laoghaire and Howth. The DART is usually the practical transport choice if your only aim is getting from one place to the other.

The value comes from combining transport with a scenic experience. You get an hour on the bay, access to views unavailable from the train, and a chance to arrive in Howth by water. The included discount toward the DART also helps if you plan to return by rail.

I would consider the price fair for visitors who want a memorable coastal outing and do not want to spend the entire day on a larger organized tour. It is less compelling for anyone who dislikes boats, wants detailed guiding at every point, or simply needs the fastest connection.

The experience becomes better value when you use it as part of a full day. Begin in Dun Laoghaire, sail to Howth, have lunch or walk around the harbor, then return by DART. That turns a 60 to 70-minute ferry ride into a flexible coastal itinerary.

Weather, seating, and practical comfort

The weather is the biggest variable. A bright, calm day can make the bay look exceptional, with sailing boats scattered across the water and clear views toward the coast. A wet or windy day can still be enjoyable from the covered area, but you will lose some of the open-air feeling.

Bring comfortable shoes and comfortable clothes, as advised. Add a warm layer even if the forecast looks mild. The upper deck is best for photographs, but you may want to move downstairs during rain or stronger wind.

The cruise is suitable for all ages, and children under three can join free. Families should find the changing views and possible seal sightings easy to enjoy, while older children may appreciate the boat ride itself as much as the scenery.

Dogs have also been welcomed on board, with one outing including a dog named Murphy who became popular with the other passengers. Since policies can change, confirm current pet arrangements when booking if you plan to bring an animal.

The crew are an important part of the tone. Friendly service, help with questions, and local suggestions can make a short trip feel personal. Eugene, in particular, has been helpful with advice about places to eat in Howth, including a recommendation for chowder at The Brass Monkey.

Who should book this Dublin Bay cruise?

I would recommend this cruise to anyone who wants a scenic half-day addition to Dublin rather than another indoor attraction. It works especially well for first-time visitors who want to understand the shape of the bay, families looking for an easy outing, and locals who have only seen the coastline from the road or train.

It is also a good choice if you are already planning to visit Howth. The boat makes the journey there part of the experience and lets you return by DART. Wildlife fans should keep watch near the harbor for seals, while photographers will want a place on the upper deck.

I would think twice if you need guaranteed sunshine, dislike wind or boat movement, or expect a fully live-guided tour. Commentary is available, but it may be hard to hear from downstairs, particularly when you choose shelter from poor weather.

The activity offers free cancellation up to 24 hours before departure, and you can reserve now while paying later. Those terms give you some flexibility, though you should still check the available sailing time before building the rest of your day around it.

Should you book the St Bridget?

Book it if you want to see Dublin Bay from a fresh angle and plan to spend time in Howth. The strongest reasons are the broad coastal views, the relaxed one-way route, the possible seals at the harbor, and the easy DART return.

Choose a calm or bright day if you can, but do not cancel a trip automatically because of clouds. The covered area keeps the outing workable, and weather can change quickly. Just bring a jacket and aim for the upper deck when it is comfortable.

For $32, you are paying for more than transport. You are buying an hour of changing views, a pleasant break from city streets, and a practical way to link two of Dublin’s finest coastal stops. That makes it a worthwhile choice for a flexible day by the bay.
