$561.00 dollars for your tag and license, you must have your hunters Ed card period, they will not give you a license without it. GJgo said right when he said food and Don't freeze to death, you will easily eat three times what you normally would on a hunt at lower elevations in a day, and the only seasons you can hunt without drawing are the 2nd,3rd,and 4th season so expect snow I've worked and hunted in Colorado and let me tell you It will snow and snow alot in short amount of time so be prepared, Another good thing that GJgo said( not in these words but) Colorado is an opportunity state not a quality state(unless you draw a sweet tag) So when you do see a bull shoot it, because if you think that your gonna hold out for a 350 bull on public ground your sadly mistaken, oh and by the way they have antler restrictions your bull has to have 4 points or better, my favorite shot on any animal is right through both front shoulders a little higher than half way, drops them in there tracks and kills them instantly. I've shot a ton of elk and deer and believe me this shot works very well, I also shoot a 338 edge ( I wonder if that helps at all ha ha ha)Like GJgo said forest service, BLM, national ground are all you got unless you get a landowner voucher Wich can cost upwards of 3000 dollars for an expensive one, and the higher the better and by that I mean timberline or just under it and on the north facing slopes with nasty thick cover, you will run into people so be prepared but most don't lime to hike to were the elk are some do but most don't. As far as packing one out, Elk are big critters so be prepared with good sharp knives and good quality game bags (I like T.A.G. Bags) have a good saw also just in case, a quality pack such as eberlestock, bad lands, or my favorite Mystery Ranch will make your life during the pack out alot easier, with a good quality pack with Internal frame a healthy full grown corn fed man can pack a Completly boned out bull elk off he mountain in four trips, it will be heavy but you can don't it with a well constructed pack ive dont it many, many, many times and believe me when I say it will be heavy, also don't quote me on this but I'm pretty sure that the horns have to come out last but I could be wrong, an the sex organs have to be attached to the hind quarters, period they do not fudge on that in any way, sorry so long and I hope his helps a little and all I can say is be prepared and good luck and buy maps....good ones !!!!!!
