Bettles Alaska is supposedly the single best place to view it. I haven't been myself. Chena is usually considered #2, but it is much easier to get to(I think).

I am far from an expert on this, but have been to Bettles. There isn't much there at all. It will cost nearly $350 pp r/t to fly there from Fairbanks.

If I were you, I would ask Chena Hot Springs for other recommendations.

I was strictly speaking seeing the Northern Lights. From what I've read, I can't imagine staying a couple of days in Bettles, much less 10.

spiro--I suggest going and experiencing it for yourself instead of just reading about it. The area is amazing!!!!! The residents of Bettles are probably the nicest you will meet anywhere. Granted, the town itself isn't a draw, but get just a few miles from there and it is pure heaven. BTW, we saw an aurora on our fist night after hiking in to our relatives cabin way up in the bush.

I apologize for not expanding for the OP. I was trying to say that Bettles is expensive to get to if you only want to go to see the northern lights. If you want to explore the area further though, it is priceless!!! I am sure the locals can give you much better information that I can. You might also check on Trip Advisor as the Alaska forum is full of great posters that know the areas really well.

mms,
I meant in the winter. I actually plan on going twice there. I do want to see it in the winter(not sure how long to actually stay there though). I think there would be much more to do in the summer, but of course much less chance of seeing an aurora.

Why in one post do you say "there isn't much there at all" and then in the next you say "the area is amazing"

I read extensively before going somewhere this remote. Noone had mentioned Bettles and since the OP specifically asked about seeing Northern Lights is the reason I mentioned Bettles. If seeing the NL was my priority that would certainly be a consideration, I would think.
The boards are very slow here for a bout the past year. I always like to put "I haven't been there", just to be honest.

I have always wanted to see Gates of the ARC, Kobuk and more there. Have been to Alaska only once for a few days(Kenai Fjords and very edge of Lake Clark-at Wolverine Creek fishing/bear viewing area). Haven't even made it to Denali. Wrangel looks great as well. Finding the time to do it is my main problem. I rarely have that much time off, I ususally just take 3 or 4 long weekend trips each year.

Spiro--When I said there isn't much there was specifically about the town. The surrounding area though is much different. It is an outdoors paradise! Hopefully that clears it up for you. We have a relative who lives north of Bettles, just on the edge of the Gates of the Arctic. He homesteaded there over 40 years ago.

Anyone has viewed northern lights in Aug-Sep?

Yes. DS saw them several times in August and then when we were there in September we saw them twice.
