Dublin: Dublin Bay Cruise from Dun Laoghaire to Howth

Dublin looks different from a ferry deck. This one-way sail on the St Bridget from Dun Laoghaire to Howth turns Dublin Bay into your travel photo set, with coastal landmarks you just cannot get by bus or train.

I love the constant shoreline views, from the Dublin Mountains to spots like Joyce’s Martello Tower and the Baily Lighthouse. I also love the wildlife moment at Howth Harbor, where seals swim close enough to watch for a while.

The main drawback is simple: water weather. The trip can be windy and cold, and on-board audio can be tough to hear unless you choose your spot wisely.

Key things to know before you board

• St Bridget cruise for a true water-level view of Dublin Bay
• Howth Harbor seal watching right as you arrive
• Landmarks en route including Bull Island, Ireland’s Eye, Lambay Island, Dalkey Island, Joyce’s Martello Tower, and the Baily Lighthouse
• Optional return ferry can be booked when you board
• Discounted DART voucher after the sailing, for an easy city return
• Weather matters, so dress for wind and bring a layer

A Sail That Shows Dublin Bay From the Right Angle

If you have only ever seen Dublin from the roads, this cruise changes your picture fast. One of the best parts is that you are not just moving from point A to point B, you are gliding along a living coastline. From the water, Dublin feels larger, looser, and a lot more marine.

I also like the simplicity of the plan. You get the sail from Dun Laoghaire toward Howth, then you get dropped at Howth so you can keep going on foot, or head back using public transit. At around an hour (the ride is listed around 60-70 minutes), it is long enough to feel like an outing, but short enough that it does not derail your day.

And yes, it is a very “do it once” kind of experience. Not because it is flashy, but because the view genuinely belongs to this kind of transport. Dublin Bay is simply better experienced from the water.

Meet St Bridget at East Pier, Just Before the Bandstand

Your starting point is East Pier in Dun Laoghaire, just before the Bandstand. That matters because it sets the tone for the day. You do not have to hunt around a huge terminal. You are close to the waterfront, and the cruise starts right in the mood of being on the bay.

The trip is one-way, and the finish point is listed as West Pier. So plan your timing with the assumption that you are arriving in Howth and then sorting your return after the sailing. This is where the discounted DART voucher comes in, and it is also where the optional return ferry helps if you want to go back by boat.

What You See Moving Past the Dublin Coast

This cruise is built around the sights you can spot from sea level. Expect views of the Dublin Mountains and multiple coastal landmarks, plus islands you would never see this clearly from land.

Here are the highlights you should keep an eye out for:

• Bull Island, including its role as a wildlife reserve
• Ireland’s Eye and Lambay Island out in the bay area
• Dalkey Island near the route’s sweep
• Joyce’s Martello Tower, a famous coastal feature named for the Martello tower tradition
• Baily Lighthouse, another recognizable marker along this stretch of coastline

What I like about this list is that it is not just “things you pass.” It is a run of points that helps you understand the geography. You start to see how Dublin Bay turns into a patchwork of headlands, islands, and protective coastal structures.

Also, you might get surprise wildlife. One review mentioned seeing a Portuguese man o war jellyfish. Another mentioned dolphins showing up. Wildlife sightings are never guaranteed, but the bay is the right place to be patient.

On-Board Staff, Stories, and the Deck Choice That Matters

A big part of the experience is the people on board. The staff come off as friendly and genuinely helpful. One named staff member, Eugene, stood out for being upbeat and sharing practical local advice, including a recommendation for a place to eat, the Brass Monkey, for fish and chowder.

There is also on-board interpretation. Some trips use stories and myths tied to the route, and you may also have an audio guide. One downside I noticed from a review is that the audio can be hard to hear from the lower deck. If you want to catch explanations clearly, aim for the upper deck when conditions allow.

Deck strategy for real life:

• If the weather is rough, the lower area can be a good comfort play because it is more protected.
• If the sky behaves, the upper deck is where you tend to get the best views and photo angles.

And do not forget a basic reality check. On water, wind is wind. Bring a jacket even if the city looks mild.

The Howth Arrival: Harbor Energy and Seal Spotting

Howth is the part of the day that feels like a reward. You are moving from city-edge scenery into a coastal fishing village vibe. Once you reach the harbor area, the focus shifts from “look at the coastline” to “look at the water in front of you.”

The standout here is seal spotting at Howth Harbor. Multiple reviews point to seals swimming nearby, and the sightings are close enough to watch and photograph. This is one of the reasons the cruise feels more than scenic. It has that living-bay payoff.

Howth itself is also a great place to wander once you are docked. The area is known for fish restaurants and for walks along the coast. If you like pairing a short boat ride with an easy walking break, this is a strong match.

One more small tip: if you arrive and want to keep your day moving, have your plan ready for food and walking before you dock. It saves time when you are hungry and the harbor is busy.

Value and Price: Why $32 Feels Reasonable Here

The price listed is about $32 per person. For a one-way cruise of around an hour, that can sound like a lot until you compare it to what you are actually buying.

You are paying for:

• A one-hour, water-level viewpoint of Dublin Bay that you cannot replicate with normal sightseeing
• A structured route where you pass major landmarks like Martello Tower and the lighthouse
• Wildlife potential at Howth Harbor, especially seals
• A voucher for a discounted DART trip after sailing

That voucher is not just a perk, it changes how you plan your return. Instead of figuring out how to get back at the end of the day, you get a built-in way to use the train system.

If you plan to go back by public transit anyway, the value reads even better. And if you would rather return by ferry, there is an option to book the return trip when you board. That flexibility matters if the timing of trains does not work for your schedule.

Weather, Clothes, and a Smooth Ride Plan

This cruise runs on the bay, so weather is part of the deal. One review described the start as windy with light rain, then the weather improving after. Another mentioned bumpy ride moments, which is normal for open water depending on conditions.

So your best move is to dress for the water, not the sidewalk.

Bring:

• Comfortable shoes if you plan to walk around Howth
• Comfortable clothes, plus a layer for wind

If you feel sensitive to motion, keep an extra layer between you and the cold. The ride is generally described as smooth and safe, but no one can control the day’s sea feel.

Who This Cruise Suits Best

This is a strong option for a lot of travel styles:

• Couples and solo travelers who want an easy, scenic outing
• Families with kids, since it is suitable for all ages
• People who want a short activity that still feels different from typical city sightseeing
• Anyone who loves seeing wildlife without turning it into a separate full-day tour

If you are traveling with time limits, this cruise makes sense because the commitment is small: about an hour. If you are staying longer, pair it with a walk in Howth so the day has both a moving and a resting part.

Also, one review noted a dog joining the trip and doing well with other passengers. The official pet policy is not spelled out in the details you have, but the experience itself suggests it can be workable for at least some passengers. If you are bringing a pet, it is smart to confirm with the operator before you go.

Quick Reality Check: What Might Not Be Perfect

Most people seem to love it for the views and the harbor moment. The areas to watch are mostly practical:

• Audio clarity can depend on where you sit
• Weather can shift quickly, and the wind can make the deck chilly
• It is one-way, so you must plan how you will get back after arriving

If you are the type who hates being cold on exposed areas, be ready to stay in the sheltered portion when needed.

Should You Book the Dublin Bay Cruise From Dun Laoghaire to Howth?

Book it if you want:

• A simple one-hour Dublin activity with a truly different perspective
• Seal spotting potential in Howth Harbor
• Coastal landmarks like Joyce’s Martello Tower and Baily Lighthouse without needing a car
• A price that feels fair once you factor in the DART discount for your return

Skip it if:

• You strongly dislike boat time and you get uncomfortable with wind or motion
