Barrow isn't a place for "sightseeing tours" Very very small town. There are several packages that include the flight from Fairbanks, hotel and native show. Not much else there. I went on a private float plane trip bowhead whale watching, but I also spent 3 days there.
If you really want to see Alaska natives, then take a flight to
Kotzebu and Nome. This will take you above the Arctic Circle
and give you a taste of "old" Alaska. This was an "unforgetable"
trip for us several years ago.
