This paved, multi-use path is popular with runners and walkers as well as bike commuters but is also a fantastic way to explore the Denver area on a long weekend ride away from traffic.

Clear Creek, a vibrant waterway roughly 66 miles long, originates in the Rocky Mountains west of Denver, finally meeting with the South Platte River. The contrast in the water's color and flow is often noticeable, with Clear Creek's clear, fast-moving water meeting the South Platte's slower, sometimes more opaque flow.

Take a moment to appreciate the park's namesake—the two sparkling lakes. They provide a picturesque backdrop for any activity, whether you're relaxing on a bench or actively exploring the park. You can find a few wood carving sculptures that showcase the beauty of nature.
