Colorado is a campers paradise. Just step outside your tent and you can be surrounded by beautiful views. Most of Colorado is just about bug free do to its dry weather, which is an added bonus to making camping more enjoyable. Colorado was the first state I was able to sleep out under the stars and not get eaten alive. However Kremmling CO has the greatest amount of mosquitoes I have ever experienced, and I'm from Minnesota which is the mosquito capital.
There are hundreds of free off the grid camp site all over the state. If you're lucky enough to come to Colorado in early fall, I recommend checking out the Idaho Springs area. All of the leaves are changing colors and and it's amazing. In the mountains the "fall" season is very quick, the leaves turn colors and fall off in a matter of a week so you have a small window of time to change this magnificent site. Meanwhile down in Denver the leaves could just be starting to change colors, while up in the mountains they have already fallen off.
