The Hollows at Phantom Lake YMCA

Step into an enchanting autumn evening at Wisconsin's oldest youth camp, where thousands of hand-carved jack-o-lanterns transform the wooded trails and lakeside grounds into magical fantasy worlds. Families will wander through imaginative scenes—fairy lands, gnome villages, mermaids, witches, and more—that transport visitors through a one-of-a-kind Halloween experience. The Hollows runs on select weekends throughout October, with grounds opening at 6 p.m. Tickets are sold by time slot (adults $20, children $12), and it's best to arrive around 15 minutes before your scheduled time, though early visitors can enjoy the concessions stand. Note that the trails aren't particularly stroller-friendly, and the event runs rain or shine with no refunds available. Your admission directly supports Phantom Lake YMCA Camp's mission of providing inclusive, transformative experiences for children of all ages and abilities. The proceeds fund camp scholarships, day and residential programs, and accessibility services that help every child experience camp regardless of background or need. This is a wonderful way to celebrate the season while supporting a meaningful cause right in the Mukwonago community.
