A Dublin Bay cruise feels like a moving postcard. This one runs along the city’s coast, from Howth to Dun Laoghaire, with big-name sights like lighthouses and islands right from the water.

I especially like the mix of scenery and structure. You get clear landmarks, Howth Head and the Baily and Kish Lighthouses, plus on-board commentary that helps you spot what you are looking at. I also enjoy that it is not a long haul, so it works even on a packed day.

One heads-up: if the water turns a bit choppy, you may spend more time inside to stay comfortable, and space can feel tight. Pack for wind and motion.

Key highlights worth circling

• Howth to Dun Laoghaire views, with nonstop coastal landmarks
• Irelands Eye and Lambay Island sailing by to the north
• Baily and Kish Lighthouses on the route for classic Dublin Bay photo angles
• Bull Island wildlife sanctuary views as you cross the bay
• Dalkey Island appearing before you enter Dun Laoghaire Harbour
• On-board commentary and a captain described as funny and friendly

How the Howth to Dun Laoghaire cruise really works

This trip is built for an easy win: a short cruise where you spend most of the time looking outward instead of waiting around. You board in Howth at West Pier, just opposite Aqua Restaurant, then you head across Dublin Bay to Dun Laoghaire Harbour and finish at the East Pier area.

The total time is listed around 60 to 70 minutes, which is long enough to get a real sense of the bay without burning half your day. If you like coastal views, lighthouses, and the feeling of watching Dublin from a different angle, this duration is a sweet spot.

There is also a practical bonus for the way back. The experience includes a DART discount voucher for your return journey, even though the cruise itself is one-way only. So you can pair boat time with rail time without overplanning.

Getting on board St Bridget, plus coffee and windproof planning

The boat is the St Bridget, and the vibe is casual. You are cruising with time to sit, look, and listen. Drinks are not included, but there is coffee and wine available on board, so you can still warm up or sip something while you watch the shoreline slide by.

In my opinion, the biggest “comfort factor” on this kind of bay cruise is clothing. Even when the day feels mild on land, Dublin Bay can bring wind. Bring comfortable layers and expect you might want a place near the outside for photos, then retreat inside if the sea state changes.

One more practical point: the route is close to landmarks, so you are standing up, shifting seats, and checking which side of the boat offers the best view. If you want uninterrupted sightlines for photos, arrive a little early and claim a spot you can work from without constantly squeezing past people.

Departing Howth: cliffs, headlands, and that first coastline rush

You start in Howth, and the first leg sets the tone. As you pull away from West Pier, you pass by the iconic Howth Cliffs and then round Howth Head. This is the part of Dublin Bay where the coast feels dramatic fast. You are not just seeing a shoreline, you are seeing the structure of it, the way the headlands bend and the water moves around them.

This section is also where you get your “orientation” moment. Once you see Howth’s coastline from the water, the rest of the bay makes more sense. It is easier to connect what you see on maps with real geography, which is why I like cruises like this even when the route feels short.

You also get a good sense of scale. Inland, Howth can feel like a small peninsula. On the water, it becomes a whole system of cliffs, edges, and bays, which makes the whole Dublin coastline feel more like one connected area instead of separate places.

Irelands Eye and Lambay Island: the north side scenery people remember

After Howth’s headland views, the route turns toward the north-side islands: Irelands Eye and Lambay Island. Sailing past them gives you a sense of how Dublin Bay isn’t just water and city. It is islands, protected zones, and wildlife corridors.

Both islands are known as a standout part of the region’s outdoor character. Even when you cannot step onto them, seeing them from the cruise makes their presence feel real. You get that “wait, that is close” feeling, which makes the whole bay feel more approachable than it can from land.

This is also a good time to slow down and look long. The best views are often not the first ten minutes you board. As the cruise finds its track, landmarks line up and you get steadier sightlines. If you are photographing, this is when you can experiment with angles.

Lighthouses on the water: Baily and Kish as your navigation anchors

One of the most “Dublin Bay classic” parts is passing the Baily and Kish Lighthouses. These are the kind of landmarks that instantly make you feel like you are in a real coastal route, not just a casual sightseeing loop.

The key value here is understanding. The on-board commentary helps you connect the lighthouses to what you are seeing. Instead of random points on the horizon, you get names and context, which makes the cruise more satisfying if you like learning as you go.

If you care about photos, lighthouses give you high-contrast subjects. They look strong even when light is flat or the sky is doing its usual Irish thing. Aim for moments when the boat angle lines up with the lighthouse and the shoreline behind it, since that creates depth in your images.

Bull Island wildlife sanctuary: the bay gets character

As you cross Dublin Bay, you pass by the Bull Island area, described here as a world famous wildlife sanctuary. This section matters because it adds a different mood to the cruise.

Early in the trip, you are focused on headlands and built landmarks like lighthouses. Bull Island shifts the attention toward nature and protection. Even if wildlife sightings are not guaranteed, seeing a sanctuary from the water tells you the bay has rules and purpose, not just scenery.

I like this part because it makes the cruise feel more than a sightseeing line. It is a glimpse of the bay as an ecosystem. That is the moment when Dublin feels like a coastal city that shares space with living habitats.

If you are traveling with kids, this is also the easiest “nature payoff” section. It gives you something to talk about besides ships and buildings.

Dalkey Island and the approach into Dun Laoghaire Harbour

As the cruise continues, Dalkey Island comes into view. This is a nice bridge moment because it connects earlier sights with the final arrival. You watch the bay open up a bit, then the waterway narrows visually as you approach the harbour area.

Finally, you enter Dun Laoghaire Harbour, where the whole experience starts to feel anchored and real. The harbour approach gives you that sense of arrival, plus the chance to catch different viewpoints that you would not get walking the waterfront.

You finish at the East Pier, and that is where the rest of your day can snap into place. You are not stuck waiting in the same place all night. You have a clear endpoint, and you can transition to food, a wander, or the rail back toward Dublin depending on your plans.

Price and value: why $28 can feel like a bargain

At about $28 per person for roughly an hour to 70 minutes, the value here comes from what you actually buy: access to Dublin Bay viewpoints in one continuous route.

This is not just “sit on a boat.” You are paying for proximity to key landmarks, including Howth Cliffs, Howth Head, islands like Irelands Eye and Lambay, and the lighthouse pass. For the time, that is a lot of named scenery.

Then add the included DART discount voucher for the return journey. Even though the cruise is one-way, this voucher helps you keep your overall transport cost down and makes the combination of boat plus rail feel tidy.

Also note what is not included. Drinks and snacks are not included, so if you plan to buy coffee or a glass of wine, treat it as an optional add-on. That keeps your budget predictable, especially if you are traveling as a group.

Who this cruise suits best (and who might not love it)

I think this cruise is ideal for people who want Dublin Bay as a visual highlight without a long day trip. It is also a great fit if you are doing a first visit and you want context fast. You see how Howth juts out into the bay, how the headlands shape the water, and how Dun Laoghaire sits as a gateway harbour.

It is also family-friendly and listed as suitable for all ages, including families and infants. The time frame helps with that, because you are not committing to a multi-hour excursion.

Where it might be less ideal is if you are very sensitive to choppy water or you hate the idea of possibly going inside for comfort. The cruise can still be enjoyable in those conditions, but your best experience will come if you dress for wind and plan to be flexible with where you watch from.

Smart tips: seats, timing, and what to bring

The cruise is short, so your prep matters. Here is what I would do to make it feel smooth.

• Bring comfortable shoes and comfortable clothes. You may move around for photos and to find your preferred viewing spot.
• Dress for wind. Even if the morning is warm, Dublin Bay can feel cooler once you are moving.
• If sea conditions look rough, plan to split time between outside and inside. You can still enjoy the sights, just not always from the rail.
• Have your camera ready for lighthouses and islands. These are the high-impact moments where photos are easiest.

If you are pairing it with the DART, take advantage of that built-in logic. The experience notes that you can take the DART to Howth before your sailing. That is one of the best ways to keep the day stress-free, because you avoid trying to solve parking or timing around a seaside meeting point.

Add-on value in the real world: using Dun Laoghaire after the cruise

Because the cruise ends at the harbour, Dun Laoghaire becomes a natural next step. You can grab food, stroll the waterfront, or simply use the harbour time to reset.

The time in the boat gives you the bay views. The time after gives you the local atmosphere. That combination is why I like this kind of one-way cruise. It builds a loop in your head, from Howth’s coast to Dun Laoghaire’s harbour, without demanding extra travel time.

And if you are planning your return, the included DART discount voucher helps you keep the overall cost and timing manageable.

Should you book this Dublin Bay cruise from Howth to Dun Laoghaire?

Book it if you want a short, scenic, landmark-filled Dublin Bay experience that feels easy to plug into your itinerary. The route is built around major sights like Howth Head, Baily and Kish Lighthouses, Irelands Eye, Lambay Island, and the Bull Island wildlife sanctuary area, then it finishes with a proper harbour arrival at Dun Laoghaire.

I would skip it only if you strongly dislike time on open water when conditions might change, or if you are looking for a long, in-depth guided land tour. This is a cruise, so your reward is what you see from the water during that hour to 70 minutes.

If you can dress for wind and you like straightforward sightseeing with helpful on-board commentary, this one is a solid value at around $28 per person plus the return help from the DART discount voucher.
