Visiting Glenveagh National Park

Glenveagh Castle lies deep in the heart of the Glenveagh National Park in Donegal which is the second-largest national park in Ireland. With a dark history, Glenveagh Castle today and the grounds of the Glenveagh National Park provide some stunning walking and hiking trails.

You will get to experience the final trail of those who had to leave their beloved country to travel to the Americas. Stand on the bridge of tears and understand how your ancestors felt when they had to leave. 

How to get to Glenveagh National Park

Glenveagh National Park

Glenveagh Castle is located within the National Park which is 24km northwest of Letterkenny, Donegal and can be reached by driving through the villages of Kilmacrennan or Church Hill.

To get to Glenveagh Castle from Letterkenny,  if you are in Derry simply follow the signs to Letterkenny and then take the (N56) road through Kilmacrennan, turning left onto the Gweedore road (R255), or alternatively via Church Hill, and pass the Gartan and Akibbon lakes (R251).   From Donegal Town, we take the N15 and it’s about an hour and a bit of drive.

If you need a cup of tea or coffee or simply a rest to enjoy the stunning views you can stop where the little pod The Mini Bean pulls up and serves refreshments all day.

On your way to Glenveagh Castle, you will pass a gorgeous little stone bridge with spectacular views of Muckish Mountain and to the side of the road, you will see a large stone with writing on it. The writing these days is barely legible and it is written in Irish Gaelic.

What to see at Glenveagh

The Bridge of Tears, Donegal

a large stone with faintly engraved gaelic in Glenveagh National Park - a memorial to those escaping the famine this is the place where their families said there last goodbyes

The translation is roughly as:

“Friends and relatives of the person emigrating would come this far. Here they parted. This is the Bridge of Tears”. 

This route used to lead to Derry from where the ships would depart for new lands in America, Australia, Scotland and England. The family of those emigrating would walk with them towards the Muckish Gap and here they would say goodbye. Crossing this bridge meant that the family would never see their loved one again and there is a sense of longing and loneliness that hangs in the air here.

The Bridge inspired Percy French to write one of his most famous songs “The Irish Mother”, and inspired Clannad’s beautiful “The Bridge of Tears”.

The Park is the second largest National Park in Ireland with over 170 square kilometres of the hillside above Glenveagh Castle on the shore of Lough Veagh. It is a drive of just under 50 minutes from Letterkenny.

Glenveagh National Park is an extraordinarily beautiful place to visit. The park has a wide variety of walks and trails and this place is truly one of the wildest and most beautiful places in Ireland to visit.

Glenveagh National Park is second only to Connemara in size and its largest feature is the stunning Lough Veagh which is a deep and long lake fed by the River Veagh. This area is among the densest woodland in all of Ireland and its environment includes moorland, bogs, mountains, forests and lakes.

Errigal and surrounding areas are within Glenveagh boundaries, and the main entrance lies a 10-minute drive from the Errigal Car Park. There is a visitor’s centre where you can obtain walking maps of the trails that are marked throughout the park, as well as grabbing a cup of tea and a shuttle bus to visit Glenveagh Castle.

This is incredible hill walking country and the mountains set in this rugged landscaper will entrance any climber. From Errigal to Muckish. Slieve Snaght, Loch Veagh and Lough Garten you will find views beyond anything you can imagine. I would highly recommend that you stay in the area and take at least 2 days to really see this part of Donegal County.

Glenveagh National Park map: walks

The Lakeside Walk is a 3.5 km trail that is considered fairly easy on a flat gravel path and it takes around 40 minutes. The trails take you from the visitor centre to Glenveagh Castle and continue along the shores of Lough Veagh. The Owencarrow River that you pass is full of breeding salmon, trout, freshwater mussels, otters and eels. Following the trail, you will pass a blanket bog, wet heath habitats including peat bogs and get some wonderful views of the castle and the valley of Glenveagh

The Glen or Bridle Path Walk is not a looped walk so you can arrange a pick up by the Walkers Bus. This walk is around 8km and takes approximately 2 hours or more. It rises pretty gently towards the end of the walk. Along the walk, you will see the old derelict settlement and stands of oaks with outstanding views of Lough Veagh.

Glenveagh National Park

The Lough Inshagh Walk is another non-looped walk so not only do you walk for an hour around the km you must walk back or arrange a car pick up at Gartan where the walk ends. This path used to connect Glenveagh Castle to the village of Church Hill. It is a supremely peaceful walk and you may be lucky to spot some red deer on the path. The wild landscape takes you past the bogs and you may see some Golden Eagles and Ravens. You will end up at St. Colmcille’s birthplace in Gartan.

Glenveagh Castle History

Glenveagh has a dark history in its stones that isn’t talked about when you take a tour of the castle, but in the area, legend has it that the place is haunted.

The builder, John George Adair, of Glenveagh Castle was considered minor gentry who had done very well for himself and ended up marrying an American heiress. The castle was built in the 19th century and designed to look like Balmoral, Queen Victoria’s favourite castle in Scotland.

Adair’s first glimpse of the Glenveagh loch and valley was blown away by the site and he was “enchanted by the surpassing beauty of the scenery”. So Adair bought several tracts, land, formed the estate, and brought his new bride Cornelia Wadsworth of New York to live at Glenveagh.

During the building of the castle in 1861, John Adair decided to clear the land of its tenants. Nobody is sure why he suddenly decided upon this action. Stories have it that it may have been the murder of his steward James Murray or an incident that took place with the tenants. Apparently, while hunting one day Adair was surrounded and intimidated by his tenants. This was not due to the great Irish Famine but happened many years later. Whatever the reason a nasty, bitter eviction took place in which 244, men, women and children were forcibly evicted from their homes and left to fend for themselves.

Glenveagh National Park

As a result of this horrendous eviction the Donegal Relief Committee was formed and they paid for passage for any person evicted, (who wanted to go) to Australia where they were given plots of land to farm.

In 1873, the castle was complete but the couple spent more and more time in America. In 1885, on the way back to Ireland from Texas, Adair died suddenly in St.Louis, Missouri.

Cornelia, John Adair’s widow was a much kinder landlord and was known to be very generous with the poor of the area. Cornelia added a round tower and a new wing to the castle as well as began the development of the gardens.  She added what were known as “Pleasure Grounds,” in Victorian times and these were quite separate from the kitchen gardens.

Glenveagh National Park

During the first World War, Cornelia opened the castle up to house and shelter wounded Belgian soldiers and continued to live in the castle herself until 1916.

In 1929, the Castle was sold to Arthur Kingsley Porter, a Harvard professor of Fine Arts. Porter came to Glenveagh to study Irish archaeology and culture. He and his wife Lucy moved among the wealthy art and literary cliques of their day and entertained them royally at Glenveagh.

Unfortunately in 1933 while visiting Inishbofin Island Porter went for a walk and never returned. His wife leased the castle to Mrs McIlhinny from Philadelphia and her son Henry and returned home to America. In 1936, Henry who loved Glenveagh returned to Ireland and bought the estate.

The McIlhinny family is quite famous in the US for both the invention of the gas meter and Tabasco sauce.

Henry McIlhenny loved a party and invited many a celebrity to come and stay at the castle. Guests included Greta Garbo, Marilyn Monroe, Rosemary Clooney, Yehudi Menuhin, and many more.

It was a lavish lifestyle and McIlhenny was said to be a “very kind” employer. There were 12 indoor staff, 8 gardeners, chauffeurs, and kitchen staff all to take care of the many guests. The swimming pool was heated, extravagant parties were held and the guests spent their days having picnics, deer-hunting sessions, afternoon teas and very formal dinners with live entertainment and dancing. Jazz king George Melly and English artist Derek Hill were just some of Glenveagh’s guests.

Marylin Monroe and other famous Hollywood celebrities partied at Glenveagh Castle and swam in the pool at the edge of the loch. Henry brought about a glorious return to the “big house” lifestyle with picnics, deer-hunting parties, afternoon teas and formal dinners.

The estate was of course set in an absolutely stunning landscape of mountains and rugged boglands. Henry not only restored the estate but he took great pleasure in developing the gardens.

The Glenveagh Gardens

Henry hired the famous garden designer Lanning Roper from New Jersey and brought him to Ireland to work with the English nurseryman James Russell to create a unique garden oasis. Plants were brought in from the four corners of the world, South America, Tasmania and China.

They added an incredible formal Italian Garden with beautiful statuary, a second walled garden and a neo-gothic conservatory.

The castle’s interior is also remarkable. Each room is designed specifically for a particular function. There is an elegant dining room with all the dishes and tableware designed for the room and some outstanding Landseer paintings. The music room has an antique Irish harp, the library with shelves upon shelves of books.

The Blue Room is American styled furniture of soft pale oak and satinwood, which was purchased by Cornelia Adair. You can take the guided tour of the castle, which costs 7 Euros per adult and is well worth the price. After the tour, you can wander the gardens and take a walk down to the Loch to admire the pool once used by Marilyn Monroe.

In 1975, Henry sold the Glenveagh Castle estate to the Irish government, who then created the Glenveagh National Park. In 1983, Glenveagh Castle was given to the country and became part of the park. In 1986, Henry moved back to the USA where he passed away and the Irish government opened Glenveagh castle to the world.

There’s a lovely little tearoom called the Thyme Out Cafe right beside Glenveagh Castle. Sit down take a break and just admire the view with some traditional Irish dishes and a cup of tea.
