Ferry from Ireland to the Isle of Man — Larne and Dublin sailings explained

If you’re coming from Ireland or Northern Ireland, you’ve got two ferry ports and one flight to choose from. The Steam Packet sails to Douglas from Larne all year and from Dublin in season. Belfast is no longer on the map. This page covers both routes: when they run, what they cost, how to get to each port, and the ETA rules that catch out overseas visitors coming via Dublin. For the English routes and the ships, see the Isle of Man ferry.

The two routes at a glance

	Larne – Douglas	Dublin – Douglas
When	All year	Seasonal
How often	Three a week (Mon, Wed, Fri)	Twice a week in spring 2027 (Thu, Sun)
Crossing	4 hr 30 min	4 hr 30 min on Ben-my-Chree
Leaves Ireland	15:45, arrives Douglas 20:15	15:45, arrives Douglas 20:15
Leaves Douglas	09:30, arrives 14:00	09:30, arrives 14:00

Days and times are from the Steam Packet’s Irish sailings timetable (opens in a new tab), covering 1 April 2026 to 14 May 2027 (checked September 2026). Both routes start from £26 (€31.75) for a foot passenger and £98.50 (€117) for a car, each way, and children under 16 sail free.

That pattern makes a same-day return from Ireland impossible. You leave in the afternoon and the boat home leaves Douglas the next sailing day at 09:30. Plan on at least two nights; a weekend break fits.

The timetable isn’t the whole story this autumn. With Manxman out of service and Ben-my-Chree covering Heysham, the fast craft Manannan has been running Larne instead. On 28 September 2026 the sailing left Larne at 10:42 and was due into Douglas at 13:45, according to the Steam Packet’s sailing status (opens in a new tab) page. Go by the time on your booking, not the PDF.

Larne, the replacement for Belfast

The Steam Packet stopped sailing to Belfast in December 2025 and moved its Northern Ireland service to Larne, about 20 miles up the Antrim coast. The first sailings were in April 2026. From July 2026, Ben-my-Chree has run it three times a week all year, and the company has committed to the route for two years (Steam Packet (opens in a new tab)).

From the Steam Packet’s Larne port page (opens in a new tab) (September 2026):

• Address: Larne Port, Larne, BT40 1AS.
• By train: Larne Harbour station is at the port, with an hourly direct train from Belfast. The Steam Packet quotes £11.
• Parking: two car parks with 405 spaces. The first 20 minutes are free, then £0.80 an hour, capped at £8 per 24 hours.
• Check-in: opens at least 1 hour 30 minutes before sailing. Last check-in is 45 minutes before for vehicles and 25 minutes for foot passengers.
• Facilities: a vending machine. Eat before you arrive.

Dublin, the seasonal route

Dublin has a patchy recent history. The 2026 season started with Manannan sailings, but everything from 23 July to 1 October 2026 was cancelled because of berth problems linked to disruption at Holyhead, according to the Steam Packet’s Dublin route page (opens in a new tab). The published timetable brings Dublin back on 25 March 2027, on Ben-my-Chree, on Thursdays and Sundays. Dates after mid-May 2027 hadn’t been published when we checked.

From the Steam Packet’s Dublin port page (opens in a new tab) (September 2026):

• Terminal: Dublin Port Terminal 1, Terminal Road South, on the north bank of the Liffey about 6km east of the city centre. It’s shared with Irish Ferries.
• Getting there: Nolan Coaches’ FerryLink shuttle runs from Connolly and Heuston stations and the quays for €4.50 each way, cashless. Dublin Bus also serves the Ferry Terminal stop on Tolka Quay (stop 2270).
• Parking: pay and display outside the terminal, €2 an hour, €9 per 24 hours or €50 a week. Clampers operate, and the release fee is €125.
• Check-in: same as Larne. It opens at least 1 hour 30 minutes before, and last check-in is 45 minutes (vehicles) or 25 minutes (foot) before sailing.
• Facilities: a café and 24-hour vending machines in the waiting room.

Coming from outside the UK and Ireland: the ETA

This is the part that catches people out. Since 23 April 2026 the Isle of Man has required an Electronic Travel Authorisation from visitors who don’t need a visa, in line with the UK (gov.im (opens in a new tab)).

• You don’t need one if you’re a British or Irish citizen, or a resident of Ireland travelling from Ireland, the UK, Jersey or Guernsey.
• You do need one if you’re a non-visa national from elsewhere, and that includes Americans, Canadians and EU citizens who land in Dublin and carry on to the island. Being legally in Ireland isn’t enough on its own.
• A UK ETA counts. The Steam Packet says it costs £20, lasts two years (or until your passport expires) and is applied for through GOV.UK or the UK ETA app. Most are approved within minutes, but apply at least three working days ahead (Steam Packet (opens in a new tab)).

The Steam Packet is legally required to check your ETA before you board. If it isn’t approved and linked to your passport, you don’t travel. What British and Irish travellers need is in passports and ID. There’s more on the island’s status in is the Isle of Man in the UK.

Or fly from Dublin

If you’re not bringing a car, the plane is usually the better bet. Aer Lingus Regional flies from Dublin to Ronaldsway all year, in under an hour. There were no scheduled flights from Belfast on the airport’s routes list (opens in a new tab) in September 2026. All the detail is in flights to the Isle of Man.

The ferry makes sense if you’re bringing a car, a motorbike or a dog. It also makes sense from Northern Ireland, when Larne is on your doorstep and Dublin airport isn’t.

When you land

Both routes arrive at the Sea Terminal in Douglas. There’s a taxi rank outside and the Lord Street bus station about 400 metres away. At 20:15 the buses to the far end of the island are thinning out, so check the last bus before relying on one. See getting around the Isle of Man.
