No, not all of Colorado is full of mountains, but the scenery in Colorado is hard to beat! Mountains are abundant of course as is the crisp clean air that goes along with them, does it get any better than that? Oh wait, did I mention the forests of amazing trees, pristine rivers, tons of National Parks, and rivers, streams and reservoirs full of fish? There are, of course, the mountain ranges, but 40% of the state is made up of the Eatern Plains, which is known for its agriculture and livestock.  Southern Colorado is home to the tallest sand dunes in North America, the Great Sand Dunes, and the Western region of the state is known for its Orchards and wineries. Get out of the city and into the Colorado wilderness, you wont regret it!
