I really recommend joining their tour! The pre-trip instructions at the beginning were very detailed. All the equipment was complete and clean, so you didn't have to bring anything with you. The helicopter seats and groups were carefully arranged (the seats for the outbound and return trips were swapped), and the helicopter was also very new. The on-site glacier tour guide was friendly and professional 👍, and took us to explore the ice cave. We were lucky that it was sunny that day, but the temperature was still very low. It would get hot after walking around. It is recommended that you bring sunglasses, the sunlight is very glaring and the ultraviolet intensity is off the charts, so be sure to apply sunscreen! I think this trip is worth it, the icebergs are magnificent and full of memories💯
