What a fabulous place to visit, we spent over 3 hours walking around the Ulster Museum. They have displays on pretty much everything you can imagine, wildlife, under water creatures, ice age, stone age, bronze age.
The "Age of the Dinosaur" exhibition was also running while we were there, 6 huge animatronic dinosaurs, so realistic. Unfortunately there was no photograph allowed in that area, Ben was amazed with the exhibition, so life-like. If you 're ever in Belfast I'd highly recommend you visit the Ulster Museum.
