If you feel the need for speed, check out Glacier Jetski Adventures out of Whittier. Run by native Alaskan and white-water rafting guide Charlie and his Aussie wife, Bec, these tours bring adventurers past icebergs, soaring glaciers, towering waterfalls, and more in Blackstone Bay in Prince William Sound. The trip covers 60 miles on the jet ski. Drysuits, neoprene water shoes, helmets, and life jackets are provided for comfort and protection. The choice of the Sea-Doo SPARK watercraft is a sound one, considering that they’re extremely quiet ( great for wildlife viewing) and fuel efficient ( great for the planet). Of course, they’re also really fast!
