Some quick need-to-knows about Glenveagh Castle

The Glenveagh Castle website is hugely confusing… they list opening hours on one page on then on the same page say the castle is closed. So, please take the information below with a pinch of salt. We’ve emailed them and tried to call them but have yet to get an answer.
1. Location
Glenveagh Castle is located on the shores of Lough Veagh in Glenveagh National Park. It’s a 25-minute drive from Gweedore, Dunfanaghy and Letterkenny Town.
2. Opening hours
According to their website (updated May 2022), in the summer months the park opens at 9.15am and closes at 5.30pm and in the winter it opens at 8.30am and closes at 5pm. I’d take these with a pinch of salt as there’s a lot of dated info on their website (we’ve tweeted them to check).
3. Admission
Admission to the castle is €7 for an adult, €5 for a concession ticket, €15 for a family ticket (no info on how many kids) and kids under 6 go free. It’s free to enter the park itself.
4. The bus
There’s a bus service that runs from the car park to the head of the Glen and Lough Inshagh Gate near Glenveagh Castle. You can buy a ticket from the visitor centre in the car park for €3. Unfortunately, their website contains zero info on when it runs.
Glenveagh Castle History

A wealthy land speculator from Co. Laois called John George Adair initially purchased several small holdings between 1857-9, eventually establishing the estate of Glenveagh.
Adair would later incur infamy in Donegal and Ireland as a most hated landlord when he ruthlessly evicted 244 tenants from their homes in the Derryveagh Evictions.
Legend has it that one woman with 6 children ended up putting a curse on the castle so that anyone who owned it would never have children. The curse is believed to have come true as some owners never did.
The construction of the castle
After Adair married his American born wife Cornelia, he started constructing Glenveagh Castle. Construction began in 1867 and ended in 1873.
It was his dream to create a hunting estate in the highlands of Donegal but tragedy (or karma) would strike and he suddenly passed away in 1885.
Disaster at Glenveagh National Park Castle
After his passing, Cornelia took over, introducing deer stalking in the estate and continually making improvements to the castle, including laying out the gardens.
After Cornelia’s passing in 1921, Glenveagh Castle fell into decay until it’s next owner Professor Arthur Kingsley Porter of Harvard University in 1929.
He initially came to Ireland to study Irish culture and archaeology however in 1933, while visiting Inishbofin Island, mysteriously disappeared.
Better times for the castle
In 1937, Mr Henry McIlhenny of Philadelphia bought the estate, an Irish American who’s father grew up a few miles north of Glenveagh.
Mr McIllhenny devoted a lot of time improving the gardens and restoring Glenveagh National Park Castle.
In 1975, Mr McIllhenny sold the estate to the Office of Public Works which allowed the creation of Glenveagh National Park, and in 1983, Glenveagh Castle was bestowed to the nation, with the National Park opening to the public a year later and the castle in 1986.
