Tullamore & Birr Castle Private Tour
Whiskey and wonder in the unhurried midlands: the Great Telescope and gardens of Birr Castle, a Tullamore DEW tasting, and back lanes past tower houses the tour buses never find.
For seventy years, the biggest telescope on Earth stood not in an observatory but in an Irish castle garden. The Leviathan of Parsonstown, built by the Third Earl of Rosse in 1845, still points at the sky from the grounds of Birr Castle — the centrepiece of a demesne that also holds Ireland's tallest treehouse and gardens of real distinction.
Pair that with Tullamore DEW's whiskey experience in the town that gave the blend its initials, add a couple of tower-house castles on the back roads, and you have the midlands day in full: genuinely interesting, entirely unhurried, and refreshingly free of crowds. Arrange your date through the custom tour form.

Suggested itinerary
Every tour is private, so this outline flexes around your group, the weather, and the day's best light.
- 1
Birr Castle Demesne
The morning at Birr: the restored Great Telescope demonstrates its workings daily in season, the science centre tells the remarkable Parsons family story, and the gardens hold champion trees and the formal terraces above the river.
- 2
Lunch in Birr's Georgian centre
Birr is one of Ireland's best-preserved Georgian towns — lunch on Emmet Square sits nicely between the castle and the road east.
- 3
Tullamore DEW
The distillery experience covers the triple-blend story and finishes with a comparative tasting. The initials, incidentally, belong to Daniel E. Williams, the manager who built the brand.
- 4
Clonony Castle & Shannonbridge
Homeward by the scenic route: the tower house of Clonony, where Anne Boleyn's cousins are buried, and the Shannon crossing at Shannonbridge beneath its Napoleonic gun battery.
Good to know
- Birr's telescope demonstrations run seasonally — dates are checked when booking.
- Tullamore tastings swap to soft options for drivers, minors, and abstainers.
- Clonony Castle is privately restored; access depends on the owner's schedule, and the exterior alone merits the stop.
- This day pairs naturally with the Athlone & Clonmacnoise half-day for a full midlands itinerary.
- Ideal shoulder-season tour — everything on the route works in the rain.
Frequently asked questions
What is special about the Birr telescope?
The 72-inch Leviathan was the largest telescope in the world from 1845 to 1917 and was used to discover the spiral structure of galaxies. The restored instrument still moves daily in season, and the story of building it in the Irish midlands is as compelling as the science.
Does the tour suit whiskey beginners?
Yes — Tullamore DEW's visit is a friendly introduction rather than a connoisseur's deep-dive, and the tasting explains the difference between pot still, malt, and grain in plain language.
Is this tour good for families?
Very. Birr's treehouse adventure area is Ireland's largest, the telescope fascinates most ages, and the distillery portion can be swapped for more castle time when travelling with younger children.
Where does the day start?
Athlone and Tullamore are the natural bases, and midlands hotels are all within easy collection range. Dublin departures add about an hour each way and remain comfortable.
