Red Rocks, Denver

Red Rocks Amphitheatre on the outskirts of Denver is a jaw-dropping concert venue recognised for its unique rock formations and stunning views.

Its geology dates back to the Jurassic period nearly 160 million years ago, where the gradual movement of the earth resulted in sandstone ledges forming the “walls” of the amphitheatre.

The park opens one hour before sunrise for visitors to hike the trails.

On certain days, hundreds of yoga enthusiasts gather on the terraces, which are up to a mile high, at 7am to enjoy downward dogs from a different perspective. colorado.com
