What: #MileHighAutumn
When: Through November 7
Denver residents, we’re at it again with another exciting photo contest! This time, we’re embracing the incredible colors of autumn alongside ways to care for our urban canopy this fall.
Leaf your mark: Join our fall photo contest.
Participating is easy!

Snap a photo of a colorful tree, a pile of raked leaves or your favorite Celebri-Tree. It can be a single leaf, a branch, a whole tree or an entire orchard. It can be just a tree or you with a tree. It could even be your kiddo (or doggo) jumping in leaves – the choice is yours!
Post the photo to Instagram using the hashtag #MileHighAutumn.
The contest runs from Oct. 1 through Nov. 7, 2025. Entry deadline is Nov. 7 at 11:59 p.m. MT.
How will the winners be selected?
Denver residents who submit a photo(s) will be entered into a drawing. Winners of a $25 Ace Hardware gift card will be selected biweekly (Oct. 10, Oct. 17 and Oct. 31 ). All entries from all weeks will be eligible to win the grand prize of a $200 Ace Hardware gift card.
The fine print.
No purchase necessary. Entrants are eligible to win prizes by posting a photo with the hashtag #MileHighAutumn to Instagram.
Denver’s Office of the City Forester and Denver Parks & Recreation have the right to use all submitted images on social media, websites, print or digital media. Photographers will not be compensated for the use of the photo outside of this contest.
