Ok, so my first answer is EVERYWHERE. From Denver you can see mountains. Just West of Denver is endless beauty.
I love the winter, it's just wonderful.
We moved here 4 years ago from Texas and never look back.
Just about 100% of the places require a leash, so if you're expecting free roam, I wouldn't coun't on it. There is wildlife everywhere, most trails require dog's on a leash and you WILL get a ticket if a ranger finds you with a loose dog. It's detrimental to the wildlife to have a loose dog and they take it seriously.
No joke I have seen the following hiking: moose, elk, wolves, coyotes, rattlesnake, moutain lion, bear droppings - YIKES, lots of deer, sheep, long horn ram
Estes Park is a fun but very touristy place and beautiful as the foot of the rocky mountians. Estes Park is the inspiration for THE SHINING and Steven King filmed the SHINING mini series right there in Estes Park at the famous Stanley hote. Oh, and there isn't the famous garden as seen in the movie. Elk are EVERYWHERE. It's a small town, so if you are spending a week, plan on taking a day trip. The major resorts are not far away, Breckenrdige, Vail etc... Another interesting place is NEDERLAND and a nice drive to the mountains.
Lots of places to see and things to do.
And... if you come in the winter time there is WORLD CLASS skiing.
Skiing doesn't start until November, but by October, there will definlty be snow in the mountains. Depending on when in November, you may be able to get some skiing in.
Ask if you have more questions.
