Become a Sponsor
The Christmas Tree Lane Association (CTLA) invites you to become a valued sponsor of one of the most cherished and historic holiday events in Southern California.
Located on Santa Rosa Avenue in Altadena (between Woodbury Avenue and Altadena Drive), Christmas Tree Lane is recognized as the oldest large-scale outdoor Christmas lighting display in the United States. For over 100 years, the Lane’s towering deodar cedar trees — also known as the “Mile of Christmas Trees” — have been beautifully illuminated each holiday season with over 20,000 sparkling lights.
This treasured tradition officially begins with the annual Lighting Ceremony and Winterfest, a family-friendly celebration featuring live entertainment, local artisans, food vendors, community booths, and holiday festivities for all ages.

2025 Sponsorship
Though the Lane suffered some minor damage during the catastrophic Eaton Fire; our community suffered large-scale devastation and as we kick off the Christmas Season with the annual Lighting Festival and Winterfest, which is sponsored by the community, we are mindful that many lost homes and businesses. Considering this, we have simplified sponsorship to make things easier for those who would like to participate. We will not have sponsorship levels, be printing programs, or running the app this year, but will instead be utilizing several social media platforms, including our updated website, to highlight our sponsors throughout the season. All sponsors will be listed on the website’s sponsor page with a link to their websites and space for a community message (up to 4 lines). At the 2024 event, our visitor numbers grew to an estimated 10,000 revelers. As the season approaches, we are experiencing a surge in media interest and anticipating even larger crowds than in years past: we expect many in the LA area to turn out in support of Christmas Tree Lane and the Altadena community.
The sponsorship deadline is November 7, 2025. If you have any questions, please feel free to reach out to sponsorships@christmastreelane.net.
