Dublin: Dublin Bay Cruise from Howth to Dun Laoghaire

Dublin Bay looks best from the water, and this cruise gives you a useful one-way trip rather than a boat ride that simply circles back. From Howth’s West Pier, you pass Ireland’s Eye and Lambay Island, round Howth Head, then cross the bay toward Dun Laoghaire.

I like two things here: the changing views, from cliffs and lighthouses to islands and harbour walls, and the easy transport plan. You can take the DART to Howth, sail across the bay, then use the DART again from Dun Laoghaire. The main drawback is that a choppy sea may send you indoors, where space can feel limited.

Key points to know before sailing

• The route is one-way: You sail from Howth to Dun Laoghaire, not back to Howth.
• The crossing takes 60 to 70 minutes: That is enough time for a proper view of Dublin Bay without taking up a whole day.
• You pass several landmarks: Look for Ireland’s Eye, Lambay Island, Howth Head, Baily Lighthouse, Kish Lighthouse, Bull Island, and Dalkey Island.
• The DART fits naturally into the plan: Take the train to Howth before departure and use the return discount voucher afterward.
• The onboard setting is simple: You can buy coffee or wine, but drinks and snacks are not included.
• Sea conditions matter: The outside views are the reason to go, but rougher water can make the deck less comfortable.

Why this Dublin Bay crossing works so well

This is not just a sightseeing boat that leaves from Dublin, shows you a few landmarks, and returns to the same pier. It is a practical link between two of Dublin County’s best seaside towns. You start in Howth, with its cliffs and headland, and finish in Dun Laoghaire, where the harbour gives you a different view of the bay.

That one-way design makes the cruise especially useful if you want to combine both places in one day. Begin with the DART ride to Howth, spend some time around the pier or peninsula, then board the St Bridget for the crossing. After arriving at Dun Laoghaire, you can use the DART for your return journey, with a discount voucher included.

At about $28 per person, the price is reasonable if you value the transport as well as the scenery. A standard sightseeing boat can feel expensive when it only provides a loop. Here, your ticket moves you across the bay and turns two separate coastal stops into one connected outing.

The cruise is also short enough to fit into a wider Dublin plan. You do not need to give up a full day, though you should allow extra time for getting to Howth, finding the West Pier, and checking the sailing time you select.

Starting at Howth’s West Pier

Departure is from the West Pier in Howth, opposite Aqua Restaurant. That is a useful detail because Howth has several piers and waterfront areas, so you should not simply arrive at the village and assume every boat leaves from the same spot.

The meeting point puts you close to Howth Harbour, where you can get your bearings before boarding. If you arrive early, you might find time to look around the waterfront, but keep your departure time in mind. The activity does not include a long guided visit in Howth, so any extra time there is yours to plan.

The DART is the sensible way to reach Howth. The rail line makes the beginning of the trip straightforward, and the included discount voucher for the return journey helps keep the full outing affordable. You are not required to drive, find parking, or arrange a separate transfer between the two coastal towns.

Wear comfortable shoes and comfortable clothing. That advice is plain but useful, since you may spend part of the cruise moving between the outside viewing area and the indoor section. Dublin Bay weather can change quickly, and a pleasant departure does not guarantee calm conditions for the whole crossing.

Ireland’s Eye and Lambay Island from the north

Once the St Bridget leaves Howth, the views open toward the islands north of the bay. Ireland’s Eye is close to Howth and gives the first clear sense that you are leaving the harbour area behind. Lambay Island appears farther out, adding distance and scale to the view.

These early sights help you understand Howth’s setting better than a view from land alone. From shore, the headland can seem like the end of Dublin. From the boat, you see how it reaches into the bay and how the islands sit beyond it.

The exact quality of the view depends on weather and your position onboard. If you want the best chance of seeing the landmarks, move outside when conditions allow, but do not expect every view to remain clear if the boat rolls or the air turns hazy.

The onboard bar serves coffee and wine, which can make the crossing feel relaxed. Drinks are not included, so plan to pay separately if you want one. Snacks are also not included, and the supplied details do not promise a meal service, so eat beforehand if you need something more substantial.

Along Howth Cliffs and around Howth Head

The most dramatic part of the route comes as the boat passes Howth Cliffs and rounds Howth Head. This is where the cruise earns its place in a Dublin day. You see the rocky coastline from below, with the headland changing shape as the boat moves past it.

The view is different from a walk on the cliffs. A coastal path gives you height and close contact with the land. The boat gives you distance, showing the full sweep of the cliffs and the headland in one frame. If you have already walked around Howth, the cruise still adds another angle.

Baily Lighthouse is one of the key sights on this stretch. Its position near Howth Head makes it easy to connect the lighthouse with the coastline around it. The cruise also passes Kish Lighthouse, giving you a second marker out in the bay and a reminder that this is a working stretch of water, not only a scenic one.

Onboard commentary and friendly service are part of the experience. The captain is described as funny and friendly, which matters on a short cruise because a bit of personality can make the crossing feel less like a basic transfer. Still, the commentary should be treated as a helpful layer, not a full guided tour of every part of Dublin’s coast.

Bull Island and the open crossing

After Howth Head, the boat passes the area around Bull Island before crossing the wider bay. The route gives you a gradual change in scenery: cliffs and headlands fade behind you, and the open water becomes the main view.

This is also the section most likely to feel exposed if the sea is choppy. One useful point to remember is that outside space may be limited. On calm days, you will want to spend as much time outdoors as possible. If the water becomes unsettled, you may choose the indoor area, but space can feel tight when several people do the same.

That is the main practical trade-off. This is a boat ride, not a land-based viewpoint with guaranteed stability. If you are sensitive to motion, sit where you feel most comfortable and keep your expectations realistic. The experience is suitable for all ages, including families and infants, but conditions on the day still affect comfort.

The crossing itself is not long. At 60 to 70 minutes, it gives you a good amount of time on the water without requiring a major commitment. For families, that shorter length can be an advantage. For photographers, it provides a series of views, though cloud, wind, and the boat’s movement may make perfect shots difficult.

Dalkey Island and the approach to Dun Laoghaire

As the boat crosses toward the south side of Dublin Bay, Dalkey Island comes into view. The island creates a clear change from the more rugged feel of Howth. You are now approaching the Dalkey and Dun Laoghaire side of the bay, where the shoreline feels more settled and the harbour becomes the focus.

Dun Laoghaire Harbour is the final major sight before arrival. Its piers and open water make a strong ending to the crossing. The boat’s approach gives you time to shift from coastal scenery to the town’s waterfront setting.

The cruise finishes at Dun Laoghaire’s East Pier. The activity is one-way, so do not plan to return to the West Pier by boat. Instead, use the DART discount voucher for your return journey, or arrange your own onward plans if Dun Laoghaire is your final stop.

This finish is a real advantage if you want to spend time in Dun Laoghaire after sailing. You can treat the boat as the connection between two coastal visits rather than an isolated attraction. The supplied information does not include a guided activity after arrival, so your time in Dun Laoghaire is independent.

What the $28 price includes

The $28 price covers the ferry ticket from Howth to Dun Laoghaire. It also includes a DART discount voucher for the return journey, which adds practical value beyond the boat ride itself.

You still pay for drinks or snacks onboard. Coffee or wine is available, but neither is included in the ticket. Keep that in mind when comparing the cost with other Dublin activities.

For me, the value depends on how you use the route. If you only want a boat ride and do not care about visiting Howth or Dun Laoghaire, the price may feel less compelling. If you already want to see both coastal towns, the ticket combines transport and sightseeing in one hour-long outing.

The trip also avoids a common problem with short cruises: having to retrace the same route. You see the bay from a moving viewpoint, then arrive somewhere different. That makes the experience more useful for a full day plan.

Who will enjoy this cruise most

I would recommend it to families, couples, friends, and solo visitors who want a low-effort way to see Dublin Bay. The short duration works well if you want scenery without signing up for a full-day boat trip.

It suits you particularly well if you plan to use public transport. The DART connection is simple in principle, and the return discount voucher keeps the route tied to Dublin’s rail network. It is also a good choice for anyone who enjoys coastal views but does not want a demanding walk.

Photographers should choose a day when visibility looks promising and should be ready to move between indoor and outdoor areas. The route has plenty of recognizable subjects, including lighthouses, islands, cliffs, and harbour structures, but the weather controls how much detail you see.

Families with infants can take part, and the experience is suitable for all ages. Comfortable clothing matters more than dressing formally. Bring a layer for the boat, and choose practical shoes for the pier and any time you spend walking around Howth or Dun Laoghaire.

You may want to skip it if you strongly dislike boats, need guaranteed outdoor seating, or want a longer, more elaborate guided tour. The onboard commentary adds interest, but this remains a straightforward 60 to 70 minute crossing.

Booking details that affect your day

You can cancel up to 24 hours before departure for a full refund, and the reserve-now, pay-later option gives you some flexibility while your Dublin plans take shape. Check the available sailing times before building your day around the trip, since the duration and departure schedule affect how long you can spend in each town.

The departure point is the West Pier in Howth, opposite Aqua Restaurant. The arrival point is the East Pier in Dun Laoghaire. Treat those as two separate locations when planning your DART connections.

The experience provider is Dublin Bay Cruises, and the vessel used for this sailing is the St Bridget. The onboard service includes a bar and commentary, but you should not expect food to be included.

The overall rating is 4.3 from 44 ratings, which fits the experience as described: strong scenery and friendly service, balanced by limited indoor space when the water becomes choppy. That is a fair picture of what you are buying.

Should you book the Howth to Dun Laoghaire cruise?

Book it if you want a scenic connection between two Dublin coastal towns, especially if you like the idea of taking the DART to Howth and returning from Dun Laoghaire after crossing the bay. The lighthouses, islands, cliffs, and harbour views give the hour a clear purpose.

I would be more cautious if you are hoping for a spacious luxury boat, a meal, or a fully guided coastal history tour. Drinks cost extra, the route is one-way, and rough water can push you indoors.

For most people, the strongest reason to book is the combination of transport and scenery. It gives you a different view of Dublin Bay and helps you build a varied day without spending a full day on the water.
