Seeley Lake used to be a good place to hunt some nice Whitetail. The secret is out of the bag now and everyone and thier brother hunts it.
Years ago I hunted it and it was a great place to get a nice Whitetail with plenty of Black Bears, but just like the rest of Montana's little nice spots this one has gone to crap. Have fun waving at the 20 or more people you will seeout in the same area hunting.
They have built the place up with cabins, mostly out of staters, but you may have some better luck if you get out of the vehicle and hunt far from the road as the place swarms with road hunters, then again this may be tough as they have put quite a few roads in.
NO grizz in the area but plenty of Yotes.
