RE: Best Place for Moose
There are alot of options for you to take a moose with your bow. Alaska as another mentioned, has the best average trophy potential. I say average potential, because just about anywhere moose are hunted can produce big moose, but the biggest moose in Alaska are bigger than the biggest moose just about anywhere else. Also, there are more moose over the 50" range in Alaska than anywhere else.
British Columbia and the Yukon Territorries are the next best place. The moose there are of the same Alaskan/Yukon subspecies in the areas that border Alaska, and the hunts are generally less expensive. The country is remote and hunts here are a true wilderness experience.
Central Canada has great numbers of moose and is an ideal place for a bow hunt, as the country is thicker than out west, so you are able to get in range easier. The moose here are not as big as out west, but you can reasonably expect a 45" plus moose, and moose in the mid 50's are very possible. A rut hunt where the guide will call them to you is a very exciting hunt and will get them in close.
Newfoundland has the highest moose densities and is a great place to take a moose. Average trophy potential is not as high as the other areas, but big moose are possible and success is virtually guaranteed.
I hope that info helps as you consider a hunt. We book hunts for outfitters in all of those regions, so if we can help you out with more info as you consider a hunt, we would be glad to help. Good hunting to you.
