Maroon Bells is one of the most photographed places in the world.

From Colorado Spring to Aspen, we didn't take the more ambitious road. The decision was right because we reached Aspen before dark and still got abundant photo opportunities along the way.

It's cloudy the whole afternoon when we were at the National Park, but the sky suddenly turned clear and the color was very sublet at sunset. Unfortunately, we have left the park and on our way to Colorado Spring at that time.

In the first day morning, we had a city tour of Denver downtown to see the State Capitol, the 16th street mall and Larimer Square.
