Set on the north shore of Dillon Reservoir at 9,050 feet, this open-air stage frames deep blue water and the jagged Tenmile Range in cinematic alpine grandeur.
Dillon Amphitheater stands directly on the north shore of the Dillon Reservoir at an elevation of 9,050 feet, framing the deep blue water and the jagged peaks of the Tenmile Range. Owned and operated by the Town of Dillon, this open-air venue is designed to merge the dramatic alpine landscape with high-caliber acoustic performance. The venue originally opened in 1993, serving for nearly twenty-five years as a modest community bandshell that hosted local jazz, country, and classical performances on summer weekends. Over the years, as the town sought to expand its cultural footprint and attract larger touring productions, the need for a modern, state-of-the-art facility became clear, leading to a complete reimagining of the waterfront site.
Between July 2017 and June 2018, the amphitheater underwent a transformative 9.7 million dollar renovation designed by the architecture firm Perkins&Will and built by JHL Constructors. The project completely rebuilt the stage and bandshell, replacing the old structure with a modern canopy engineered with a high-load roof to support complex lighting arrays and heavy sound rigging. To combat the notorious afternoon alpine winds that sweep across the reservoir, architects integrated protective wing walls into the stage design to shield performers and keep sound from dispersing. The renovation also added two new green rooms, three changing rooms, expanded backstage storage, a dedicated sound booth, and modern concession and restroom facilities. Crucially, the design team retained the original concrete seating bowl to preserve the intimate, fan-favorite sightlines while re-contouring the surrounding walkways with ADA-compliant ramps and tiered lawn seating to ensure step-free access from the main plaza to the front of the stage.
Today, the venue accommodates up to 3,656 spectators, balancing ticketed national headliners with deeply rooted community events. Since its grand reopening in 2018, which featured a sold-out run by the Colorado jam band The String Cheese Incident, the amphitheater has hosted a diverse roster of Grammy winners and touring acts. Alongside these major productions, the venue continues to honor its grassroots origins through free programming, most notably Mountain Music Mondays, a popular weekly summer concert series introduced in 2023 to bring locals and visitors together on the grassy lawn. Attending a performance at this altitude requires practical preparation. At 9,050 feet, the thin mountain air demands constant hydration, and temperatures regularly plummet into the 40s the moment the sun slips behind the peaks, making warm layers and windproof gear essential for any evening show.
At 9,050 feet, the altitude demands serious hydration: stick to empty water bottles under 32 ounces to fill inside, and keep in mind that alcohol hits twice as fast. Pack warm layers (temperatures drop into the 40s after sunset) and carry blankets over your shoulder for quick security screening. If you plan to sit on the grass, leave standard camp chairs behind: the venue strictly limits lawn chairs to low-clearance models with seats no more than five inches off the ground.
