The original plan for Juneau was to hike all day to and from Mendenhall Glacier. It's one of the only glaciers that is accessible by a reasonably short, mildly strenous hike. In order to actually get up close and touch, walk on and around a glacier it usually requires a plane/helicopter ride or a very long multi-day hike. The weather wasn't really cooperating with us on most of the trip to this point and the forecast didn't look any better as we got closer to Juneau so we shifted gears and went whale watching instead. I was slightly dissapointed I wasn't going to be able to get up close and personal with the glacier but the day proved to be great for more wild life, so option two turned out to be an excellent choice.
