Inside the Spooky Weekends at Jellystone Park Milton: Trick-or-Treat, Costume Contests, and the Last Open Dates

Some families celebrate Halloween for one night. Cute. Jellystone Park Milton celebrates it for four straight weekends, and honestly, the group chat should have been alerted weeks ago.

Starting September 25, the whole campground tips into full spooky season: costumes on repeat, candy by the bucket, and a haunted trail that turns “I’m not scared” into a very fast walk back to the campsite. If the kids have been counting down since August, and let’s be real, so have you, this is your sign.

Quick answer: what do you do at a Jellystone Park Milton Halloween weekend? Each weekend brings a costume contest for all ages (pets absolutely included), park-wide trick-or-treating, a haunted trail, the Magic Pumpkin Patch, and a site and golf-cart decorating contest where one lucky winner scores a free night of camping next Halloween. It runs four weekends, September 25 through October 18, 2026.

The Costume Contest Has No Age Limit, and Neither Do the Pets

Toddlers in dinosaur onesies. Tweens in a “low effort” costume that clearly took three weeks. The parent who swore they weren’t dressing up and is now fully committed to a group theme. Even the dog pulls a fit together.

Everyone walks the costume contest. Everyone acts humble. Everyone secretly wants the win. It is giving main character energy for the entire family, and the family Halloween events in PA rarely come this all-ages.

Trick-or-Treating, But Make It the Whole Campground

Forget circling three neighborhoods hoping the good houses are handing out the full-size bars. At this trick-or-treat campground, the candy run goes site to site, with decorated campsites all in on it and neighbors who genuinely said yes to the assignment.

The kids collect enough sugar to power a small town. The grownups collect roughly 47 nearly identical photos. Balance.

The Haunted Trail and the Magic Pumpkin Patch

For the brave, and for the “I’ll go but I’m holding your hand the whole time” crowd, the haunted trail lands right in the spooky-not-scary sweet spot. Enough thrill to feel proud after, not so much that bedtime becomes a negotiation.

Then there is the Magic Pumpkin Patch, which is the exact kind of low-key wonder that ends up living rent free in a kid’s memory. Core memory unlocked, no notes.

Decorate Your Site Like the Prize Depends On It, Because It Does

The site and golf-cart decorating contest is where things get competitive in the most wholesome way possible. String up the lights, deploy the inflatables someone swore they would stop buying, and commit to the bit.

One winner each weekend takes home a free night of camping next Halloween. That is a full year of bragging rights plus a free trip. Understood the assignment.

The Last Open Dates (Screenshot This Part)

Here is the plot twist worth planning around. These four weekends are the entire Halloween season at Jellystone Park Milton, because the park closes for the year right after the last one. And since the park is closed on actual Halloween, October 31, these weekends ARE Halloween here.

Mark the calendar:

• September 25–27: Weekend one. First costumes, first candy haul, first “wait, we get to do this four times?”
• October 2–4: Spooky season in full swing, haunted trail included.
• October 9–11: Cooler nights, bigger decorating energy, peak fall vibes.
• October 16–18: The grand finale and the last weekend of the season.

When the lights go out on October 18, that is a wrap until spring. So if watching the whole thing play out in someone else’s stories is not the vibe, booking now is the move.

Plan the Trip

Jellystone Park Milton sits in Milton, Pennsylvania, in the heart of the Susquehanna River Valley, an easy drive from Lewisburg, Williamsport, Danville, and the surrounding towns. Stays range from cozy cabins to full-hookup RV sites, tent sites, and covered wagons, so the whole crew fits however they like to camp. Pack the costumes, the comfiest hoodies, and a wagon for the candy haul.
