Designated wilderness areas would preclude landing a helicopter and/or a plane on a lake within that area, as well as taking any bike or cart in there. The only way to do a designated wilderness hunt it is go on foot with pack animals of some sort if it's for any length of time where you can't carry it in and out on your own back!!!
If youre hunting in Washington, in the Cascades. I could make some great recommendations for outfitters. If you wanted to do a drop camp.
i could also possibly hook you up horses to use. thanks, Garret
