Little ghosts and goblins are invited to search for treats and treasures throughout the haunted halls at The River of Time Museum and Exploration Center.

This scavenger hunt experience is being offered in coordination with the Maricopa County Fountain Hills Library during “Fright Night” from 6 to 7 p.m. Tuesday, Oct. 24, and again only at the River of Time Saturday, Oct. 28, from 10 a.m. to 1 p.m.

Participants are invited to stop by the Fountain Hills Library for a ghoulish experiment making screaming ghosts, create a hide-n-seek haunted house picture, devour hideous Oreo eyeball cookies and take a walk in a spider’s web.

Come in costume and use the scavenger hunt clues to discover the bats, beaver and spirits that are haunting the River of Time. Witches, spiders and skeletons will be making their appearance along the darkened pathways and special “dinosaur eggs” with treats will be passed out to those who can solve all the clues.

Selfie opportunities with costumed characters will be located throughout the haunted halls. The event is free and open to the public.

The River of Time Museum & Exploration Center is open Wednesdays through Saturdays, 10 a.m. to 4 p.m. Check out all the fall happenings at riveroftime.center.
