Haines is the "eagle" capital. A nice couple museums in town. There is scenic rafting on the river and nice kayaking on the lake. Car rental is also an option? Request their visitor guide- www.visithaines.com
The highway north out of Haines goes through the Bald Eagle Preserve. You might also look at the Kroeschel Wildlfe Park. He train animals for film telvision and has the most amazing collection of animals. Is also very knowledgeable. (For instance beofre I went there I had no idea that in general wolverines are shy and get a bad rap.) Great way to see wildlife rally up close.
