Laura Thompson
I highly recommend GondwanaEcoTours Northern Lights Adventure. Our guides, Davidand Greg, arranged many interesting daytime activities-dog sledding, Chena Hot Springs, visitsto cultural museums and a sustainable family farm. Their knowledge and passion for the areawere influential. At night, our guide, Laurie, accompanied us whenever there was Auroraactivity and helped with photography. Overall, a wonderful experience!

Wow, it might be a great experience. Group size was great, large enough for interactions（互动）, small enough to not be lost in a crowd. Activities were fun and food was hearty andgood. Great guides were personal and professional. But we were unable to keep us very warmand comfortable during the extreme cold. Think twice!

The Northern Lights tour was one of the best vacations ever. With the various things to seeand do during the day, we kept busy and very interested in each item we saw. We were veryfortunate to see the Northern Lights 5 days in a row—what a spectacular treat! All three guideswere great. Highly recommend.
