A sincere post for my friends that own and operate Exposure Alaska. They have been in business since 1999 offering true Alaska adventure tours. New this year is the Chugach Challenge offering: Fast paced and fueled by adrenaline and coffee. You’ll raft Class V rapids, ice climb on a glacier, ride the fastest zipline in Alaska and backpack in the wilderness.
Here is a review I wrote in 2013 after the last expedition I took with them (first was in 2007).
