Eldorado Canyon is part of the Colorado State Park and is situated in Boulder County, near the city of Boulder and about 50 km northwest of Colorado's largest city of Denver. The canyon is very popular among rock climbers and hikers.
My photos below were taken on the Rattlesnake Gulch Trail. This roundtrip is about 5,6 km long and at its peak you'll get a stunning view for great landscape shots.
