Bastyr University’s annual Haunted Trails is returning for another year of spooky fun. Hosted in the forest behind Bastyr University’s Kenmore campus Oct. 21-22, the event annually draws thousands of visitors and includes activities for teenagers and adults, as well as trick or treating for children ages 7 and younger. Proceeds benefit student study abroad programs, including the School of Acupuncture and Oriental Medicine’s annual study trip to China.

The fund-raiser is run entirely by volunteer teams of Bastyr University students, faculty and staff. Free event parking is available on the Bastyr University campus, 14500 Juanita Drive N.E., Kenmore.
