We didn't rush to get off the ship and found that about 30 min after we docked we were able to get off without a wait. We took the Mendenhall Glacier/ Salmon Bake excursion. We enjoyed the excursion although it was a little different than expected. The bus drops you off at the visitor center at the Glacier. You can walk to some viewing points or an amazing waterfall (about 3/4 of a mile) but you do not actually get to walk to or on the glacier. The visitor center was interesting and they had a chunk of the glacier that had broken off in the water for you to touch and see (that was neat). Then, we went to a salmon hatchery (we didn't expect this but it was interesting). They explained what a hatchery is and then they have a small animal petting area and gift shop. At the end of May the hatchery wasn't very active yet. They said in June and July there would be a lot more action with the salmon returning to lay their eggs. The salmon bake was very good. Lots of yummy food in a very comfortable setting. There was a guitar player, Alaskan husky dog, waterfall with river and abandoned mine. If I was to do this trip again I would skip the glacier and go whale watching instead. We only saw whales from the distance on the ship and we saw lots of glaciers close up in Glacier Bay. We did not explore downtown Juneau at all - it seamed pretty touristy and was about a mile from port.
