Ship: Sapphire Princess
Departure point: Vancouver, British Columbia
Sails to: Whittier, Alaska (May to August)
Explore Alaska's wild frontier with onboard naturalists on Voyage of the Glaciers. Ice thunders into the sea as you glide through Glacier Bay National Park; otters, seals, orcas and other whales splash in pristine waters. Ports offer one-of-a-kind shore excursions: Snorkel in Ketchikan through kelp forests (triple-ply wet suits keep you toasty), combine whale watching with a guided glacier hike in Juneau, and drive the dogsled at a musher's camp. The newly renovated ship is especially popular with multigenerational families and features a slew of group activities (Movies Under the Stars, family karaoke, American Idol-style contests) as well as teen clubs and adult areas. Optional add-ons include a land tour to Mount McKinley in Denali National Park.
