Hi all - I appreciate there have been a lot of posts regarding choosing between the glaciers, which is why I've tried to make my question a little more specific.
What I am really keen to see on the glaciers (although of course I appreciate the conditions are changing constantly and no guarantees can be made) is ice formations such as caves and arches which you can walk through and explore etc. I have contacted the tour operators for advice but wondered if anyone who had actually been there could offer insight - is the likelihood of seeing these features that much greater on the heli hikes (either glacier) than on the full day walking tours? Fundamentally, is the significant extra cost of the heli hikes worth it for what I am looking for in a trip?
Thanks in advance for your help. If it is of any use I am probably leaning towards Fox glacier as from what I can gather their trips are a little more 'rugged' as opposed to tourist-y.
