Things to Do in Louth: The Wee County's Best Kept Secrets

Louth is the smallest county in Ireland and one of the most rewarding to drive. In a single day you can wander a walled medieval town, climb to a mountain pass that an Iron Age war was fought over, read 1,000-year-old carvings on a high cross, and eat mussels pulled from the bay that morning. This is the local version, with the practical steers most listings leave out.

The Wee County splits neatly in two. The north is mountains and sea: the Cooley Peninsula, Carlingford and the Tain Way. The south is monastic Ireland at its richest, with Mellifont and Monasterboice a short hop from Drogheda. Pick a base and you can do either half properly in a day.

What are the must-see things to do in Louth?

Start with Carlingford and the Cooley Peninsula in the north, then add the great monastic sites near Drogheda in the south. Here is what each one is and how to do it well.

Carlingford medieval town

Carlingford is the headline act: a tight little Norman town wedged between Slieve Foy and Carlingford Lough, with the lough on one side and the Mourne Mountains across the water in the North. The lanes still follow their medieval lines, and the ruins of King John's Castle, the Mint and the Tholsel gate are all walkable in an afternoon.

The Carlingford Tourist Office runs guided town tours and castle tours from April to October, departing from the Station House. Give it three to four hours to do the town justice, and go on a weekday morning if you want the lanes to yourself before the lunch crowd arrives. The oyster bars and pubs around the square are the reward at the end.

The Cooley Peninsula and the Tain Way

The Cooley Peninsula is the dramatic bit: a finger of mountain and coast that the ancient epic, the Tain Bo Cuailnge, was set on. The Tain Way is a roughly 40km waymarked loop that climbs through the Cooley Mountains and back along the coast, with views over Carlingford Lough the whole way.

You do not have to walk the full loop to get the best of it. The drive over the Windy Gap pass between Carlingford and Omeath delivers the big views in twenty minutes, and there are shorter forest sections you can dip into. Bring layers whatever the forecast says, the mountain weather turns fast and the exposed sections catch the wind off the sea.

Old Mellifont Abbey

Mellifont, near Drogheda, was the first Cistercian monastery in Ireland, founded in 1142 by St Malachy with monks sent from Clairvaux. Its great curiosity is the lavabo, an unusual octagonal washing house where the monks rinsed their hands before meals, now a graceful ruin of arches by the river.

The grounds are free to walk year round. The OPW visitor centre and guided tours run in the summer season only, so check the Heritage Ireland listing before you set off if you want the guided version. A quiet back road links Mellifont with Monasterboice, so pair the two.

Monasterboice and the high crosses

Monasterboice is a small monastic site with an outsized treasure: Muiredach's High Cross, carved in the 10th century and reckoned the finest of all Ireland's high crosses. Each face is covered in biblical scenes still legible after a thousand years of weather, with a well-preserved round tower standing beside it.

Access is free and the site is open all the time, which makes it ideal early or late. Go in the morning when low light rakes across the carvings and brings the panels out, then read them like a stone comic strip. It takes about an hour, and it is a fitting bookend to Mellifont fifteen minutes up the road.

Where can you escape the crowds in Louth?

Carlingford gets busy in summer. These quieter corners reward a little more local knowledge.

The Carlingford Greenway

The Carlingford Greenway is a flat, traffic-free path along the old railway line beside Carlingford Lough, running roughly 7km from Carlingford toward Omeath. It is suitable for all ages, you can hire bikes in the town, and the lough and Mourne views do the heavy lifting. An easy hour or two, and a brilliant first cycle for kids.

Clogherhead and the coast

Clogherhead is a working fishing harbour with a Blue Flag beach, north of Drogheda. You can swim, walk the headland out to Port Oriel for the views, and on a good day buy fish straight off the boats at the pier. It is the kind of unfussy coastal afternoon the brochures skip, and it pairs well with a run down to Termonfeckin or up to Annagassan.

Stephenstown Pond near Knockbridge

Stephenstown Pond is a small nature park outside Dundalk with looping walking trails around a former estate lake, plenty of birdlife and a playground for younger kids. Entry is free, it suits a buggy, and it is a reliable spot to burn off energy on a grey afternoon when the mountains are wrapped in cloud.

What is there to do in Louth with kids?

Plenty beyond the ruins. The Carlingford Adventure Centre is the big one, running zip lines, kayaking, archery and laser combat for ages eight and up, with sessions pitched to different ages and abilities. Book ahead in summer and at weekends, when school and birthday groups fill the slots.

For wet-weather backup, Funtasia in Drogheda combines a waterpark with bowling and crazy golf under one roof, and the County Museum in Dundalk runs hands-on exhibits and school-holiday workshops aimed at younger children. Between the Greenway, the beach at Clogherhead and the adventure centre, you can string together a full active day without anyone hitting the wall.

Take a guided tour of Louth

If you would rather not drive, or you want the history brought to life, a guided tour is the easy way in. Two we rate, both running from Dublin if you are travelling without a car:

• Celtic Boyne Valley and Ancient Sites Day Tour from Dublin, a full-day guided trip through the wider Ancient East that takes in the monastic and prehistoric heart of the Boyne Valley on Louth's southern doorstep. Worth it if you are based in Dublin without a car and want the big history done in one go. Check dates and prices on Viator.
• Dublin to Newgrange and Monasterboice Small Group Guided Tour, a small-group day trip that pairs Newgrange with Monasterboice, the Louth high-cross site you can also reach under its own steam from Drogheda. A good shout if you want the carvings explained rather than working them out yourself. See the small-group tour on Viator.

Where to eat and drink in Louth

The food is genuinely good here, and it leans hard on the sea. The Glyde Inn at Annagassan is the standout, an award-winning seafood pub built around local Annagassan blue mussels, with traditional music on Friday nights. In Carlingford, the oyster bars around the square serve the lough's own oysters about as fresh as they come.

Out on the Cooley side, Fitzpatrick's at Rockmarshall is a long-running, characterful spot known for Cooley Mountain lamb and a famously eccentric collection of bric-a-brac on every wall. Dundalk and Drogheda both have busy independent café and craft-beer scenes if you are basing yourself in town. Book ahead at weekends, the good places fill.

Getting to Louth and getting around

Louth sits on the M1 between Dublin and Belfast, which makes it one of the easiest counties in Leinster to reach. Drogheda is about 45 minutes from Dublin Airport, Dundalk about an hour, and Carlingford another 25 minutes northeast of Dundalk on the coast road. The Enterprise and commuter trains stop at Drogheda and Dundalk if you are travelling without a car.

For the Cooley Peninsula, Carlingford and the coastal villages, a car is by far the best option, since public transport up there is thin. The official Visit Louth site maps the main driving routes and seasonal opening times if you want to plan a loop.

Make a weekend of it

Louth rewards an overnight, and it sits between two of Leinster's best history counties. To the south, the Boyne Valley spills over the county line, and the Battle of the Boyne site at Oldbridge (just across the river in Meath) pairs naturally with Mellifont and Monasterboice; it is covered in our guide to things to do in Meath. Closer to home, the county's two big towns have their own food and music scenes, mapped in our things to do in Drogheda and things to do in Dundalk guides.

The short version

Spend the first half-day in Carlingford and over the Cooley Peninsula, then drop south to Mellifont and Monasterboice near Drogheda for the monastic ruins. Add the Greenway or Clogherhead beach if the weather holds, the Adventure Centre or Funtasia if you have kids, and eat mussels at the Glyde Inn or oysters in Carlingford to finish. It is the smallest county in Ireland, and it packs more into a weekend than places three times its size.
