I'm going on an Alaskan Cruise for my honeymoon and I'm noticing that all the excursions are very expensive. My fiance and I are hoping to do one big excursion (like a helicopter ride or something). Both of us love hiking and would really like to do some hiking while we're there but don't want to pay a ridiculous price to follow someone around on a hiking trail. Are there options for us to just go hiking without a guided tour?
