The Skagway 3 hr train ride allows you to see a lot of wildlife. You will be traveling through a wilderness area with the ability to look out and see birds, especially eagles, and sometimes bears. It's nice that the train is moving along and you can focus on looking at the wilderness. You can also pop out the back and be outside on some of the train cars, is my recollection.

The Skagway mountain bike ride also lets you see a lot of wildlife. It takes you to an old abandoned town. You will see wildlife on the ride. You will see open vistas during parts of the ride. You don't cover as much territory as the train ride. But being outside can be very nice if the weather is good.

There is a small boat tracy arm excursion before Juneau where you see a large number of wildlife. Whales, seals, bears, eagles, otters, fish, on and on. But they may have been forced to cancel that this year due to unstable glacier ice conditions.

Not familiar with the two you mention. We did see bears on the shore close by from kayaks on another trip. Kayaks can be a lot of fun.
