Luckily, the weather was great! We were able to successfully board a helicopter to hike on the glacier, a truly unique experience! Definitely worth a trip to see the scenery, it's absolutely gorgeous! 🤩
Encountering a rainy day. Returning early due to the heavy rain. Experiencing being battered by icy winds and snow. Safely being transferred by helicopter. Safe travel planning.
It rained this time. The waterfall had plenty of water, but the weather was damp and cold, which reduced the time spent observing from outside the boat. Animals were also less active. Overall, it was a worthwhile experience.
