The views from the observation area are stunning. We were lucky that is wasn't windy and were able to take in the whole breathtaking sights (360). The Planetarium Northern Lights show was great as it explained simply how they come into being. There's enough information about glaciers, volcanoes, and wildlife to keep you interested without going into too much technical detail. There is a very cold ice cave which you can wander through (take a hat and gloves as it gets to -10). Great place to visit if you're looking for a wet weather activity. Should last you a good couple of hours. Nice coffee and cake in the cafe at the top too.
