we booked the 9:30am tour, and get back to cruise at 2:30pm. we saw 7-8 whales, but tails only, no breaching behaviour in Alaska. we walked to photo point trail and the falls trail, also we stopped to watch a wild bear for a while, too a lot of picture. trail time total with bear and picture was 1.5 hours with a 5 years old walk himself. Wear your rain boots for the part, since you need to walk through a shallow water to get closer to the falls.
