We arrived at Hotel Húsafell with snow and high winds accompanying us. We were interested in taking the Into the Glacier tour but on enquiry our first day was informed the tours for that day had been cancelled due to the challenging weather and it was unclear whether the tours would proceed the next day either. We booked the afternoon tour for the next day anyway just in case they could run, and we are so very glad we did. Fortunately for us, the afternoon tour did make it up the glacier to the tunnel. Although we did get stopped by the snow accumulation many times, the very skilled drivers got us through and that all just added to the thrill of the expedition. Once on the glacier we were travelling in white out conditions so didn't see the outside view, but that didn't make us feel like we weren't getting value for money at any time. Navigating by GPS lent it's own excitement. We'd like to give a special mention to our fantastic tour guide Adrian whose enthusiasm, calm demeanor, humour, and knowledge made the trip even that more special. Even if we wouldn't have made it to the tunnel, we wouldn't have requested a refund as the trip up, the scenery (for the first part), and the knowledge shared were worth it. Of course, being inside the glacier is a very unique experience where we learned about moulins, the different layers of a glacier, the different types of glacier and even got to see a crevasse from the bottom looking up. On an environmental note, the glacier is constantly re-growing inside so this is not a permanent disruption of nature and we felt the opportunity for education justified the tour. Adrian was passionate about the evidence of significant climate issues, but understandably didn't push it overly much as I'm sure he needs to be sensitive to the views of the customers as well. All around an amazing experience we were happy to have and will remember until our memories are no more.
