Some joker on here told you to skip Homer. WHAT??? :-) Haha
I primarily came here for a woman, otherwise I'd be somewhere else too.
I understand though. We have a tourist town here - and in the summer, we don't like to go down there ourselves (Homer Spit). We avoid it like the plague.
September to May are much more suitable.
The Kenai Mountains across the bay are wonderful scenery, and it's all public - my personal playground.
I've been to all the areas you mentioned. Sometimes a good road trip is just what you need. But you got a lot of miles for not many days. Like somebody said, a blur of green, and maybe some yellow. Think Green Bay Packers.
I hunted all up and down the highway between Paxson and Cantwell, and hardly saw a Ptarmy - and that's with an excellent gordon setter. That was a few years ago though. I think the later the better for them. The few I saw were way up high and way off the road. I did see lots of spruce chickens though, especially on the Cantwell end.
As others said, there are grayling there - but I didn't try for them as I would rather hunt than fish.
Lots of hunters along that road. Mostly friendly and excited to be out. Some subsistence hunting there too, I think.
We don't have much for Ptarmigan in Homer, but we have a lot of Harlequin, and if you really want a good one, I could probably help you with that as I take out some duck hunters.
I also do tours on the bay, and I know right where to find them.
But now I might be screwing up your trip as others have told you to skip Homer. Decisions. Decisions.
If it were me, I would skip Tok and Glenallen and hunt birds.
Homer is better than Seward IMO.
Whittier is interesting and beautiful, but there isn't much there.
Personally, I prefer the wilderness areas - so I love Cantwell to Paxton, or Tok to Eagle, or the road to Valdez. Beautiful long stretches of nothing there.
Coopers landing is beautiful on the way to Homer. But that is touristy as well.
I'd skip Anchorage altogether but to fly in and fly out. That city is becoming a pit!
Good luck and let us know how you do.
