With its excellent views of the Rocky Mountains, miles of hiking trails and cinnamon-hued sandstone cliffs, Red Rocks Park is a big draw for outdoors enthusiasts. Occupying 700-some acres, this impressive park offers visitors the opportunity to experience the fascinating geographic transition between the Great Plains and the Rocky Mountains. If you only have a short amount of time here, stretch your legs along the Trading Post Trail; this nearly 1 ½-mile-long path weaves through the rust-colored buttes, making for some spectacular scenery. Before you head out, travelers recommend stopping by the visitor center, which features information on the parks history and trails.

Another big draw is the expansive amphitheater, which has hosted such headliners as the Beatles, Tom Petty and John Denver. You'll soon find (and hear) that the theater – geologically formed by the red rocks – boasts amazing acoustics and an enjoyable atmosphere. But many recent visitors said that no matter the show, the majestic atmosphere makes it a good time. Even if you can't fit a concert into your schedule, many travelers agreed that the theater is worth a stop for the photos alone, while the park's visitor center features displays dedicated to past acts.
