So happy, so worth it, so much fun! A must-try experience. The driver and tour guide provided a very dedicated introduction. Another highlight was the glacier helicopter experience, simply amazing. Once we were on the glacier, the instructor led us with great reassurance, you could see the instructor was very experienced. We walked for about an hour or a little more, which was actually quite sufficient because it was a bit tiring. Also, it's not really that cold on the glacier, so you don't need to wear too many clothes.
