The Hollows at Phantom Lake YMCA

Step into a Halloween experience unlike any other. The Hollows features thousands of intricately hand-carved jack-o-lanterns displayed throughout the wooded trails and lakeside grounds of Phantom Lake YMCA Camp. As you walk through, you'll encounter whimsical themed scenes—enchanted fairy lands, gnome villages, mermaids, witches, and more—that transport visitors into imaginative fantasy worlds. It's the perfect outing for families looking for seasonal magic and a memorable evening together. Your visit directly supports the YMCA's mission to make camp accessible to all children. Ticket proceeds fund inclusion programs, day camp scholarships, residential camp opportunities, and accessibility services that help kids and families who might otherwise be unable to attend. Tickets are sold by time slot, so plan to arrive during your scheduled window. The grounds open at 6 p.m. and close one hour after the final ticket slot. This is a weekend event running throughout October, giving your family plenty of opportunities to experience this one-of-a-kind Halloween tradition at Phantom Lake YMCA Camp in Mukwonago.
