We are 2 adults who will have one full free day in Anchorage the day before we depart on the Alaska Railroad package to Kenai and Denali. We will also have 1/2 day in Anchorage at end of our RR package in Anchorage before we depart for airport home. We are looking for suggestions of activities in Anchorage. We like to walk, do easy hikes, enjoy gardens and nature. We will not have a car. Any help for things to do is appreciated.
