The bubbles are located up a short hill in the forest, the service hut is excellent - very clean, warm and facilities to make hot drinks, greeted by friendly host who explained how to get up to the bubble. They felt very private once we were there as they were a good distance away from each other. They had heated mattresses and we stayed in October and it was cold even with the mattress but we came prepared for this with extra layers. It really is a once in a lifetime experience we amazingly had a clear night so were able to stargaze seeing shooting stars through the roof of the bubble and to top it off we saw the aurora too. It’s an experience and we would highly recommend it but pack warm clothes if going in the winter!
