Bastyr University’s annual “Haunted Trails” last weekend of the season begins Friday.

Hosted in the forest behind Bastyr University’s Kenmore campus, the event concludes this weekend, Oct. 19-20. One of the biggest scarefests in the area includes frightfully enjoyable activities for teenagers and adults, as well as trick-or-treating for children ages 8 and younger. And it’s all for a good cause, as proceeds benefit student study abroad programs.

Festivities begin for ages 8 and younger with The Great Pumpkin’s Trick-or-Treating Adventure from 5-6:45 p.m., followed by the Children’s Carnival from 5:30-9 p.m. Cost is $5 per child.

Then things get scary when the Haunted Trails open from 7-11 p.m.tonight and tomorrow night. Cost is $20 per person.

Tickets are available in advance at HauntedTrails.org or at the door starting at 6:30 p.m. Please note that a limited number of tickets are sold each night. The second weekend of Haunted Trails, October 19-20, is very busy and tickets can sell out as early as 8:45 p.m. For tickets and more information visit www.hauntedtrails.org.
