In a long road trip around the U.S., we made several stops in Colorado. There were just so many beautiful sights to see. At one of those stops, in Estes Park just a little outside of Denver, there's Rocky Mountain National Park and many trails of varying difficulties. The mountains are so beautiful, you can find a nice view from just about anywhere, but you can go to the top of Prospect Mountain to look over the whole valley. There's a tram from the city to the top of the mountain. We spent the night in Boulder and not actually in Estes Park, but there were cabins available in the woods that would have been lovely to stay in had the weather been a little nicer.
