Tour Highlights

  • Join our pioneering adventure to some of Ireland's wildest and remote areas as we journey along the Atlantic coastline

  • Complete a series of unforgettable crossings, coastal swims and circumnavigations

  • Sleep each night on-board the Lady of Avenel tall ship - a 102-foot Brigantine square rigger which is your home for the week. You can even try your hand at crewing this iconic vessel!

Welcome to the Wild Side! Ireland’s Donegal coast is unlike anywhere else on earth, which explains why it was named ‘Coolest Place on the Planet’ by National Geographic Traveller. This liveaboard swimming holiday allows you to explore the natural beauty of Ireland’s dramatic Atlantic coastline and discover the untamed landscapes that exist in one of the country’s most isolated and beautiful areas.

Throughout the week, you’ll have the chance to swim in some of the most inaccessible locations in the Emerald Isle, many of which can only be reached by ship, as we swim and sail our way between the glacial loch of Lough Swilly and the quiet seaside village of Burtonport. You’ll also be able to take in the culture of this proudly independent region within The Republic of Ireland.

Our home for the week, the ‘Lady of Avenel’, is a 102-foot tall ship which includes our very own on-board chef. She will accompany us for the duration of our trip as we set up to experience the best of what Ireland’s famous Atlantic coastline has to offer.

Who is this trip for?

This trip is made up largely of crossings and some coastal swims. Conditions will be challenging, yet extremely rewarding.

Swimmers should have a sound understanding and experience of swimming in strong sea conditions and be capable of completing the average swim distance of 2.5km, prior to the start of the trip. The average daily swim distance is just under 4km (split over a minimum of two swims). Due to the nature of this trip, there is a minimum swimming speed of 30 min/km (40 min/mile).

We have given this trip Challenging grading. These trips are for experienced open water swimmers who want to push themselves.

No sailing experience is required however, the ship’s crew are happy for you to assist with onboard duties as much or as little as you like.

What's included?

  • Fully guided swimming holiday around the wild Atlantic coast of Ireland
  • Swim guides and full safety escort on all swims
  • Six nights' accommodation on-board the Lady of Avenel tall ship
  • All breakfasts
  • All lunches
  • All evening meals
  • Full ABTOT Financial Protection

What's not included?

  • Travel to and from the start of the tour

Daily Itineraries

Part of the appeal of our Lady of Avenel trips is the unpredictability of the wild areas in which we will swim. We sail when the winds are favourable, meaning a degree of flexibility is required as to when we may sail out.

Please note that the below itinerary is an example of the swims that may take place during the course of your trip, however, actual swim locations and distances can vary according to local weather and sea conditions. Your SwimTrek guides and local boat pilot will determine the most suitable swim locations each day and will let you know swim plans as soon as possible. Sailing a tall ship by its nature brings the excitement of the elements.

Trip Schedule

Start Point: The Guildhall, Derry, Londonderry, BT48 6DQ

Start Time: 16:30 on Day 1

Finish Point: The Guildhall, Derry, Londonderry, BT48 6DQ

Finish Time: 12:30 on Day 7

Day 1

After meeting your SwimTrek guides and fellow guests at The Guildhall in Derry/ Londonderry, you have a 50-minute transfer to Lough Swilly where our ship and accommodation for the week, the ‘Lady of Avenel’, is moored. After a tour of this classic rigger, we then hold a full trip briefing followed by an acclimatisation swim in Lough Swilly (light permitting). Following our swim, we hold a welcome dinner and chat further about the plan for the week ahead.

Day 2

This is the first of our full Donegal swimming days and it's a ripper. In the morning, the Lady of Avenel sails north and we stop on Lough Swilly’s western flank at Gortlosk. From here, we carry out a shallow coastal swim along to Drumnacraig beach, which features stunning white sand.

Following lunch on board our ship, we travel to Fanad Head Peninsula and carry out a swim between the two beaches that sit either side of the exposed lighthouse of the same name. From here, there is nothing to see but the vast Atlantic Ocean. In fact, if you kept swimming, Iceland is the next piece of land you would come to. The coastline here is formed of steep jagged rocks that tower above the ocean floor. Due to Fanad Head’s exposed position, you should expect some swell as we swim this stretch.

In the late afternoon, we cruise by ship around to Sheephaven Bay, which is home to one of Ireland’s most vibrant Herring fishing fleets. There is an opportunity to go ashore and stretch our legs as well as visit the Singing Pub, which looks more like a traditional Irish cottage than a pub.

Day 3

Things start to get really interesting today. We start by approaching Horn Head at the entrance to Sheephaven Bay. The 180-metre high cliffs are some of the tallest in Ireland and make the swimming here all the more spectacular. We carry out a stunning coastal swim underneath these cliffs. There are still remnants of Neolithic stone circles and tombs which dot the landscape.

Once everyone is back on board, we travel across to Tory Island, which lies eight miles off the Irish mainland. The island is steeped in history, mythology and folklore and has a unique rugged quality to it. Swimming here is rare to say the least, so some of the swims that we carry out will undoubtedly be firsts.

We head to East Town and the isthmus that separates Noughermore from the rest of the island. We circumnavigate the peninsula, which features swim throughs, sea stacks and sheer cliffs. It’s certainly a unique place and one that makes for an unforgettable experience. If conditions allow, we will moor near the island and try to enjoy what East Town has to offer in the evening.

Day 4

This morning features our first long sail as we travel from Tory Island to Owey Island and the islands nearby. During the voyage you will have an opportunity to help sail this square rigger. On route we will see Bloody Foreland and the islands of Inishsirrer, Inishmeane and Gola. It’s a dramatic scene as the wild Atlantic roars along this coastline.

In the afternoon, we carry out our first crossing of the week as we swim first around Owey Island and then hop to Cruit Island. It’s possible to see the seabed most of the way across. Once we reach Cruit, we have a chance to walk around the island and explore. The ship will moor up somewhere in this archipelago of islands where we will spend the night.

Day 5

We continue on our journey along the Donegal coast. Our next stop is Arranmore Island, a rugged and unspoilt island which hosts imposing sea cliffs, stunning bays and idyllic inland lochs. Between Arranmore and the mainland is a host of small islands and islets which make for an exciting sea swimming adventure, The underwater topography is also something to marvel at, as well as the resident grey seal population.

Today’s swims will be a mix of a coastal swim along Aranmore’s dramatic west coast and an afternoon crossing to the hundreds of island that lie in between Aranmore and the mainland.. If the weather allows, we will tuck ourselves away near Calf Island to spend the night, where there are some stunning walks to be enjoyed.

Day 6

Today we will start to head back North up the Donegal coast. There is a myriad of possible swims that we can choose from. Possible swim spots are the Bloody Foreland peninsula, should conditions be benign, otherwise we may well visit Sheephaven Bay should the weather pick up. If we make it into Sheephaven Bay, the impressive sight of Doe Castle, which was a historical stronghold of the MacSweeney Clan, dominates the skyline. Whatever option we undertake, the swims will be exhilarating and something you’re unlikely to have ever done before.

In the late afternoon, we travel past Ballyhiernan Bay and Fanad Head before arriving back into Lough Swilly where we will spend our last evening. It’s a great opportunity to reflect on the trip and the swims that we have undertaken.

Day 7

We start the morning with a pre-breakfast swim before our final group breakfast. For those making their way from back to Derry/Londonderry, your transfer will take you back to The Guildhall where your trip ends.

Location Summaries

Weather Caveat

For safety reasons, we rely on decent weather conditions when carrying out our swims.

These changes often add a touch of uniqueness to your trip and will be communicated to you by your SwimTrek guides as quickly as possible.

Given the location of this trip, the weather will play a key factor in all our swims and crossings. It should be assumed that changes will be made to the planned itinerary based on local conditions.
