Went on the Walk Through Ice and Fire tour and it was amazing. Our guide was incredibly knowledgable and very funny. Gave lots of info about the geography and geology on the way to and during our hikes. He found us an absolutely gorgeous spot to take a dip in a warm pool in the middle of the most beautiful valley I've ever seen and taught us tons about glaciers when we went hiking on a glacier. Money well spent and I'd book with them in a heartbeat!
