No, that is not sufficient time to take the public bus. We used the public bus; however, doing so necessitates a considerable walk.

It is several miles ( 10 maybe) from ship port. There are city busses that take you to a bus stop that is still a mile walk to the visitor center and then trails to close up of the glacier. Most bus drivers are helpful. There are also pay for tours to the glacier and other sites.

There are options in port to book...if they are full (as they were when we were there) take the bus trip into the National Forest, its worth a look.

Yes it would be

No - I did not see any assistance available for elderly visitors. In fact, my elderly husband stayed in the Visitors' Centre whilst I did the long walk to the Waterfall. Be aware that there is also not a lot of seating outside. Hope this helps - please let me know if I can give you any further info. regards

We purchased a combination whale watching tour and Mendenhall Glacier tour, so the bus we boarded in Juneau took us to both places, then back to the vicinity where we started, which was near our cruise ship. It is worth your while to see.

The US Forest Service has limited the types and numbers of commercial vehicles allowed in and out of the Mendenhall Glacier area. I have not seen any Uber or Lyft drivers out there and it’s likely they do not have the necessary permits from the Forest Service. If you don’t wish to walk the 1.5 miles from the public bus stop and back, I would suggest using the taxis or one of the other USFS permitted companies. If there is a group of 6 traveling together, it is pretty economical on a per person basis to hire Juneau Limousine for a custom tour and not only are they USFS permit holder but they provide transportation to anywhere you want to go in Juneau.
