We have always loved this boat trip (despite lousy weather every time) since my husband first took me to his home state of Alaska in 1987. Viewing the sea life and glaciers never gets old. Kenai Fjords Tours does an excellent job of organizing, finding animals and getting the boat to the animals, providing narration and information, and providing a good lunch. Always bring your winter and rain gear. We lugged our winter coats for our entire 2 and 1/2 week trip in May knowing we'd need them for this tour (it was the only time we wore them and we needed them). We've gone in May, June, July and August, and always needed our cold weather coats, gloves and hats. On this trip we saw multiple "rafts" of sea otters, Stellar sea lions, puffins, orca, humpback whales, gray whale, and lots of harbor seals at the calving Aialik glacier.
