Sitka is small enough to hike around town easily. There are also bike excursions for those so inclined. We hiked to the Raptor Rehabilitation Center where there were bald eagles, a falcon, owls and other birds. Then a hik back to te historical park and some hiking/shopping around downtown.
Quick Tips:
No need to buy the excursions from the cruise here. Easy to get around town by hiking. If you are not up for a couple miles of hiking, there are tours that you can get for on the dock that will drop you off wherever you want. We went with another couple and the wives took this option and got dropped off at the New Archangel dancers location and were let off before the excursions. They got front row seats :) .Best Way To Get Around:
hiking, tour bus or rent a bicycle if you want to get out to Whale Park (6 mi.)... some folks on the cruise did that and had a good experience.
