Witch's Woods at Nashoba offers Haunted Hayrides and Halloween Screampark, both of which are fright-filled adventures for kids age 6 and up.
The Haunted Hayride is the longest in New England, and the only one in Massachusetts.
Admission includes access to three haunted houses: Nightmare Mansion, Castle Morbid, and 3D Keeper's Crypt.
Nashoba also offers two self-guided attractions, a Jack O'Lantern Jamboree, and Horrorwood Chamber of Chills.
Cranmore's Ghoullog opens for the fourth season, offering a glimpse into the terror of a village struck by a mystery virus that has affected all inhabitants.
A stroll through the beleaguered village at dusk leads to the summit quad for a seven-minute ride to the Ghoullog atop the 2,000-foot peak.
Both resorts are selling season passes at pre-season rates. Nashoba is selling Adult Unlimited Passes for $625, and Junior Unlimited Passes for $575; prices increase $50 Nov. 15. Cranmore is selling Adult Unlimited Passes for $509, Adult Limited Passes (valid except Christmas, Martin Luther King Jr., and February vacation periods) for $339.
