This is a must and worth the cost to see the real Alaska!!! My husband and I are not new to Alaska and glaciers, but this was our first time in a helicopter and trekking across the ice, and it definitely won't be our last. We did the 2-hour glacier trek with our tour guide Ann and 3 others in August. We were the last group of the day and for about an hour, we were the only people on the glacier. It was an absolutely incredible experience exploring the landscape looking for waterfalls and hopping over glacial rivers, and of course drinking the glacier water! We really enjoyed the flight to and from Mendenhall as well. We flew through the mountains, over the glacier and ice field, and spotted waterfalls and beautiful sights along the way. Our tour guide Ann, our heli pilot, everyone at Northstar and our drivers were all wonderful and really enhanced the experience. We got lucky with a cloudy day so that you could really see the deep blues in the glacier. As far as the temperature, I got warm and had to roll up my sleeves about halfway through the trek, so if you tend to handle outdoor activity well in 50+° don't over-layer yourself too much since you won't have anywhere to store layers you may need to shed. I had on a beanie, tank top, sweater, and the jacket they provide, and regular leggings and the pants they provide. I'm very small-framed but maybe get hot more easily than others. The wind was a bit chilly at first but I warmed up quick despite us not having any direct sun. You won't regret exploring Alaska like this.
