I'm looking at http://www.northpolevoyages.com that advertises vacations to the North Pole on a Russian Ice breaker. Pretty cool. It's "eco travel", so they offer features like a regular schedule of lectures about the arctic environment by professional naturalists and scientists. Interestingly, it's a nuclear powered ship. Don't know how eco friendly that is, but wow. How often do you get to travel on a nuclear powered ship. It would certainly make for an interesting adventure travel vacation.

One thing I don't understand is who owns this ship. A quick search on google shows a bunch of travel companies advertising vacations on the russian icebreaker Yamal (pictured below). It was not clear to me what company actually owns and operates the ship.
