My favorite day was Juneau. We did a tour that included mendehall glacier, a salmon hatchery, and Glacier Gardens. The stop at the gardens was first and the guide did an amazing job educating about the rainforest. It was my favorite part of the day and I'm the kinda girl that finds natural scenery boring.
We did about an hour at mendehall glacier which was enough time to go to the falls and back. We also checked out the visitors center but only spent 10 minutes there before heading back to the bus.
