What should we do in Dublin?!

Two of our favorite things were: EPIC Museum and a cocktail making class at the Jameson factory.

Newgrange is fascinating. We did a day tour with https://www.newgrangetours.com/.

Rick Steves has a couple of self-guided walking tours in his Ireland guide book.

Definately have fish-n-chips at Leo Burdocks. There are a few takeaway stands around Dublin. You could share one, they give you enough, at least they used to.

Here are some options:

My #1 site in Dublin was seeing the Book of Kells and the Old Library at Trinity College. I'm a sucker for ancient illustrated manuscripts. Even though you only get to see two pages of the actual book, and it might not be an illustrated page, the entire exhibit is very informative and shows large reproductions of a lot of the illustrations. The digital exhibition (in the Red Pavilion) was "meh" to me. (The ticket that includes the digital exhibition is called "The Book of Kells Experience;" to visit the normal exhibit and library, choose the ticket for "Book of Kells and Old Library.")

edited to add: If you want to see this, book in advance. They do sell out, but I have no idea how far in advance you need to book. We went on an RS tour.

We arrived in Dublin for three nights at the end of our trip. We took the historical walking tour, in Rick Steves book, that was led by a graduate student from Trinity. It was excellent.
We also took in the museums, which far exceeded my expectations: National Museum of Ireland, National Gallery of Ireland and Chester Beatty Museum. Visited Christ Church at noon for their Peace Prayer Service.
We had the historical pass, so we took a tour of Dublin Castle and Kilmainham Gaol.
We did not go to the Guinness storehouse, which we later regretted because everyone said it’s a very unique experience.
And we walked, did the last of our Irish pub drinking and a bit of shopping before heading home. We had good final dinner of our trip at Mister S.

PS The Book of Kells was closed while we were there.

I thought the tour I took of 14 Henrietta Street was really interesting. It started as the home of a wealthy family in the 1700s and by the 1900s was a tenement housing 100 people. The last resident left in the 1970s.

I also enjoyed the EPIC Museum.

I was there in June.
The EPIC Museum is great, especially if you have Irish ancestry.
I went to the National Gallery of Ireland and the National Museum of Ireland, near to each other…...also really good.
