If you've already taken an Alaska cruise and you want to experience more of the culture, history, and scenery of the frozen north, then perhaps you'll dig a riverboat cruise in northern Canada. It's a chance to explore the Arctic up close.
The M.S. Norweta is a riverboat that cruises from the Hay River (located on the south shore of Great Slave Lake) to Inuvik, which is on the northern end of Mackenzie River. Total distance? More than 1000 miles.
This is a small ship, too, so if you'd like to experience more remote ports and and live in a quaint family-friendly atmosphere while you're aboard, this could be a nice change from your typical megaship cruise to Alaska.
Here's a blurb from the company's website:
"Historical, archaeological, flora and fauna, wildlife or lunch on shore - whatever the interest - the tour will travel new and ancient sites for everyone on board to experience.
Like any marine adventure, sleeping accommodation are compact but the ship has a large lounge, sundeck, and dining lounge. A combination of the scenic beauty of the North and an abundance of Aboriginal culture and hospitality will ensure the Adventure Traveller a vacation of a lifetime."
