The Outside Festival is back and tickets for the 2025 event go on sale at 10 a.m. Friday — just in time for holiday gifts.

Following 2024’s successful event, Boulder-based Outside Inc., has booked top-shelf musicians, and will bring back films, speakers and outdoor sporting events for the May 31 to June 1 event in downtown Denver’s Civic Center Park.

Musical acts Khruangbin (Saturday) and Lord Huron (Sunday) are the headlining acts for the 2nd Annual festival.

Sylvan Esso, Neal Francis, Husbands, Squeaky Feet and Brothers of Brass are scheduled to play Saturday, May 31 and Trampled by Turtles, Waxahatchee, Hazlett, The Copper Children,  and Cole Scheifele are scheduled to play Sunday. 

“We’re beyond excited to bring the Outside Festival and Summit back to Denver in 2025,” Denver Mayor Mike Johnston said. “Last year’s festival was a resounding success and we’re thrilled to once again spotlight Denver’s vibrant community and culture as one of the nation’s best cities to work, play, live, and visit.”

In addition to the live music element, the festival has two full days of events with adventure film screenings, athlete panels and signings, climbing experiences, yoga classes, workshops, gear demos, a kids’ zone, exciting food options, and a variety of immersive brand engagements.

The Outside Summit, a precursor to the Festival and the outdoor industry’s premier networking event attended by over 500 influential leaders, will return on Thursday, May 29, with a full day of programming on Friday, May 30, plus exclusive gatherings and festival access over the weekend.

Last year’s inaugural Outside Festival drew more than 18,000 people and generated an estimated $16 million for Denver’s local economy. With a larger footprint in 2025, organizers this year are expecting more than 25,000 attendees. In addition to Civic Center Park, the event will expand to include Lincoln Veterans Memorial Park as well as spaces inside the Denver Art Museum and the newly renovated Denver Public Library.

“Colorado’s outdoor recreation economy accounts for $66 billion annually, and is a core part of what makes our city and state so successful and vibrant,” Conor Hall, director of the Outdoor Industry for the State of Colorado said. “Bringing this event back to Colorado cements our place as a leader in this industry, and we’re thrilled to see everyone this spring.”

The event is managed by Boulder-based Outside Interactive Inc., with support from The State of Colorado’s Outdoor Recreation Industry Office and Visit Denver and executive production by Groundswell Experiential and Superfly.

“Outside’s mission has always been to encourage more people to get outdoors, discover, learn, and engage fully with all that nature provides,” Robin Thurston, CEO of Outside Interactive Inc., said. “The Outside Festival and Summit will continue to embody that same ethos, offering a space where people can engage and deepen their appreciation for the outdoors alongside others who share the same passion. We hope you’ll join us in 2025 for a weekend of adventure, growth, and community.”
