Such an incredible experience! While looking for glacier hikes to go on, the 3-4 hour one wasn’t available, but the longer hike was. I was a bit hesitant on this decision, but more than happy with it. The time allowed us to explore two ice caves and have a full experience hiking the glacier. Our tour guide Vigfus was amazing, he kept us entertained with a traditional Icelandic song, taught us some cool facts and history, and was overall so helpful. I felt completely safe and well taken care of and highly recommend this tour! I would advise to bring a snack on the hike as we had a resting period to eat before the second cave, other than that everything was perfect!
