I went on the minitrek 1/2 day glacier walk excursion and thought it was really well done. The guides were very friendly and interested in talking with us and very knowledgeable about the glacier. The hike wasn't dufficult but they were attentive and concerned for our safety the whole time. After 1 1/2 hours trekking in the ice the day ended with some scotch and cookies on top of the glacier! Nice touch! The views were great and for someone who just wanted a taste of ice trekking it was perfect! I would highly recommend it!
