Dear eagle111, thank you for visiting Perlan. Yes, Perlan stands on top of a hill with six hot-water tanks, of which 4 hold geothermal hot water - about 4 million liters each. One of them is now home to our Planetarium, and another one houses the real ice cave and glacier exhibition. Did you visit our Wonders of Iceland exhibit? Perlan is a world-class experience center where you learn all about Icelandic nature in interactive and fun ways. The highlights are a real ice cave, a first-class Planetarium, and a full-size bird cliff with augmented reality entertainment. Our Observation Deck is a fantastic place to observe the Northern Lights. Our guests saw them several times in November and December of last year. If you can't see them in the sky, our Northern Lights Planetarium movie is a perfect option for our guests. It takes you on a journey through the solar system and auroras dancing all around you surrounded by Icelandic nature. Hopefully, we will see you again to explore more of Iceland's nature at Perlan. Kindly, Steffi

Thank you, K8724, for sharing your experience with us. I am glad you stopped by. We also love the views from our observation deck.

In our exploratorium, you explore Iceland's unique nature through interactive displays, great texts, cinematic experiences, augmented reality entertainment & more. There is an exciting future ahead at Perlan & we hope to see you again. 訪ねてきてくれて、ありがとう。 Kindly, Steffi

Dear Minnie, thank you for sharing your experience with us. We are also fond of our beautiful building & happy to fill it with life and adventures. Our ice cave is only a part of our exhibition - there is so much else here to see. On one floor, we have an interactive exhibition about glaciers. On the ground floor, you experience the forces of nature, learn how Iceland came to be, watch birds in there natural habitat, virtually travel around Icelandic ocean & so much more. This December 2018, we will open a world-class Planetarium. The Icelandic Museum of Natural History will also open an exciting exhibition at Perlan this December. We hope you have a beautiful stay in Iceland & that we will see you again. All the best, Edda

Thank you, paseri, for sharing your experience with us. Did you know that access to the Viewing Deck is included in tickets to our Wonders of Iceland exhibition? Yes, visiting Perlan is perfect before, after or instead of traveling out of Reykjavík. Here, you both experience & learn to understand Iceland's nature through technology, photography & ground-breaking science. We are also excited to open a Planetarium, this winter 2018. We hope to see you again at Perlan. Have a great day, Edda
