Norwegian Fjords: Which Cruise and What to Visit?

Which cruise... and what to visit for 10 days

It depends on what you're looking for/like, your budget, etc... A big ship with lots of activities ==> MSC, Royal Caribbean, NCL

A smaller ship ==> Hurtigruten, Havila, Ponant

A more traditional experience ==> Holland America Line, Cunard, etc.

Without more details about what you're after, it's a bit tricky to give advice.....

As for what to visit, again, it depends on what you're looking for—whether it's a cultural experience, or more about hiking, landscapes, and wildlife...

There are tons of cruise options in the north, and each offers a different experience.
