The western US state of Colorado – teeming with the picturesque peaks of the Rocky Mountain range – has seen an influx of visitors looking for adventure on holiday this year, with many exploring the area around the metropolis of Denver in 2010.
Holidays in Denver benefit from the surroundings of a big city in the west, but visitors have increasingly become interested in more adventurous endeavours, such as backpacking, hiking and skiing in the area.
