The walk is long and there are not a lot of benches. However i believe you can rent a wheelchair. I did that with my dad
Once you arrive at the entrance to the pumpkin trail, near the bison exhibit, it takes about 45 minutes to walk through the show. Wait time to enter the show may vary depending on attendance. Stroller and wheelchair rentals are not available at night. If a patron is in need of a wheelchair, admissions staff will provide one at no charge on a first-come, first-served basis. The trail is fully wheelchair accessible.
I suppose this is a Halloween related question. I don't know. I was there in July. Sorry.
