Thought this place was pretty cool, informative with reading information in multiple languages, some really interesting artifacts too. Definitely a worthwhile visit if you are into srchaeology/anthropology. We spent about 1.5-2 hours here.
One of our first stops in Reykjavik and the one we enjoyed the most in all of Iceland. Used the Reykjavik card (good deal) and got there around the time it opened and were able to join a tour. Our guide was great. Learned much about Iceland's history (it's very rich and intricate).
In the Saga Museum, ensure that you get the complimentary headset and audioguide as you walk through the 17 exhibits which were dioramas of key moments in early Icelandic history. There are also signs in English next to each exhibit. It was quite dark which made taking photos a bit difficult. There were a few chairs to sit and a lot of kids were just sitting on the floor. It took me about 30 minutes to walk by all the exhibits. There is also a gift shop in the museum.
We enjoyed a photo expo on the subject of 100 years ago, 1918, and the important events in town. Spanish flu and the end of WWI. Plus an explanation of the turf houses in town. Good space.
It seems rather small from the outside but has a huge underground exhibit. Very interesting little facts and stories. Bring a lot of time to read all the info table.
