The grandaddy of outdoor music venues is this bucket list-worthy pilgrimage site that has been winning hearts and blowing minds for over 75 years. The only venue of its kind in the world, naturally carved into place by two massive sandstone monoliths, is well known for the spiritual vibe floating through the crisp mountain air 6,450 feet above sea level. From The Beatles and Hendrix back in the day to more recently a jam band mecca for acts like the Grateful Dead and Widespread Panic, these days the legendary venue hosts a diverse slate of acts with Gorillaz, Galactic, and Fleet Foxes all rolling into town this September. Located just 10 miles west of Denver, this 9,500-capacity venue and National Historic Landmark feels like another world. It’s also a gorgeous free park owned by the City of Denver, so stop by in between shows and replenish your chi with activities like hiking, mountain biking, and yoga.
