Worth a visit (and a stop in the hop on/hop off bus route). Walking through the ice cave was fun , but you may need to stoop low to get the full experience. Interesting interactive presentations around the floors too.

Not worth the price and time unless you have tons of both or need a plan C due to other cancellations. The aurora show is nice, the ice cave is pretty cool, the museum itself is fine but feels more like the 4th grade field trip spot every year. For the $35 price tag to get in, you do not get enough. The interactive pointing didn't work much at all. The view is indeed amazing, especially at sunrise when we were there. But I wish I had done the maritime museum instead.

This structure has a 360 degree viewing balcony that gives great views of Reykjavik and its surroundings. The dome/viewing area is built on top of 5 water towers. The location has a cafe and gift shop. There is also an ice cave which unfortunately we didn't get to see due to lack of time on our tour.

We went to Perlan on our first day in Iceland when we were staying in Reykjavik. It was a nice way to start the trip, giving us a good overview of the country and the landscape. Some of the films were quite good and the ice cave was fun--not as fun as the real one, but pretty cool for inside of a museum. The restaurant wasn't rotating when we were there, but the views were still fantastic and the food was surprisingly good. Tip: The items in the gift shop were nicer than the options we found almost anywhere else and the same price. We didn't buy anything while there assuming it would be higher priced, and we'd have better options elsewhere. We ended up wishing we had!

We accidentally ended up here with an Icelandic friend who had no idea about the exhibitions. A nice surprise, a lot of interesting information of how Iceland came to be and what the future looks like. The ice cave was a fun experience (what, only -15 degrees, anyone can do it! ;) ), now I read that there was a planetarium too but that one we missed. A lot of people on an August Friday, some queues to the ice cave but no extensive waiting times.

It is a very nice museum, but very small for the price. The ice cave probably cost a lot to maintain and it was not that cool. Lava show and the planetarium were ok, but not that great either that I would pay 35e again to visit, sadly.

An interesting museum about the nature and geology of Iceland. The star exhibit is an actual ice cave that you can walk through, which has been created to have the same sounds and properties of a glacier. There is an observation deck with a great view of Reykjavik and a planetarium which plays a short film about the aurora borealis. There is another very short film about volcanic eruptions and a few exhibits about glaciers and the animals of Iceland. The museum is well done but expensive for the relatively small size - it took us about 90 minutes to experience the whole thing and the cost was around $120 for 1 adult and 2 kids.

Perlan is an alternative  place to go when your real tour gets canceled.  It's a cool building with a 360° outdoor deck. There's a great view of Reykjavik from the deck. The volcano movie was just a short video that showed volcanic eruptions for about 20 minutes. The Northern Lights show in the planetarium is interesting, but I wouldn't allocate my time in Iceland to go there unless I had nothing else to do. There is an ice cave that takes a few minutes to tour. It's kind of interesting, but it's over in a few minutes.  There is a restaurant and maybe a cafe in the glass dome where you have a wonderful view of the surrounding area while dining. There's a gift shop, also.  I'd say that Perlan would be great for younger children. It's not bad by any means, and it helped fill up some time when my tour was canceled.  I'm glad I went, but one visit is sufficient. 

Great modern museum with interactive displays. The ice chamber is the highlight along with the dome cinema. Really good displays also. Walkable from downtown, around 2k. Food is expensive in Iceland and Perlan is at the top end. Best part of £15 for a large slice of cake, so eat before you go!

The amount of information in this museum is amazing, you can learn so much about the geography of Iceland and experience things in quite a few different ways. The highlight was the Northern Lights show and the Ice Cave - both were incredible and worth visiting just for those alone!! There’s also a 360 degree viewing platform at the top to look over the city. They also have a shop and ice cream parlour too. All staff were lovely and happy to answer any questions we had. Amazing technology in there, too! We walked from downtown Reykjavík, which took about 40 minutes. It is a bit of a trek up the hill, but easily doable!
