Hikers at a stream in the Arroyo Seco area
The City of Pasadena, Parks, Recreation, and Community Services Department, in partnership with the One Arroyo Foundation, invites the community to a ribbon cutting ceremony celebrating the completion of the Arroyo Seco trail improvements.
The event will take place on December 7 at 11:00 am at the Lower Arroyo Park parking area and marks a major milestone in revitalizing this cherished Pasadena resource.
The ceremony will feature remarks from Pasadena Mayor Victor M. Gordo and other community leaders. Attendees can enjoy optional activities, including a guided walk of the new trail improvements or a one-mile trail run led by the Pasadena Pacers.
