Expensive shore excursions of the town were a waste of money. Get a free walking tour map and walk the town. It can be done in 2 hours or less. Take the free bus out to the Totem Heritage Museum and Salmon Hatchery.
We rented a car and did the Mendenhall Glaciers on our terms and time. We were able to hike out to Nugget Falls and back in two hours. Most organized tours gave you one hour- which is not enough time for the hike. The downtown area of Juneau is walkable.
A quaint Alaska town set against a scenic background of snow capped mountains. Boring after 15 minutes.
The walk from the ship to the main downtown area is 1/2 mile. You can visit all the souvenir shops in under two hours. Not worth spending the entire day here.
Wish the ship spent more time here. We barely had enough time to visit the Buchart gardens, so we didn't get to visit the Empress Hotel or walk around the downtown area.
