This is my absolute dream day and I love sharing it with people visiting Alaska.  The incredible aspect of the the surrounding glacier valleys and stellar views of Spencer Glacier, along with the rafting trip floating around icebergs make this an extremely unique & memorable trip.  If you have a  passion for natural beauty, want a true full day of adventure and desire an authentic engagement with wild surroundings then the Heli Hiking trip is the trip for you.  Erin Henszey – Chugach Adventures Trip Leader from Fairbanks, Alaska.
