The "Great Jack-O'-Lantern Blaze" kicked off Friday night at Van Cortlandt Manor in Croton-on-Hudson.
The event returned to the Hudson Valley for its 18th year and features around 7,000 artistically hand-carved pumpkins.
Once inside, visitors will see everything from animals to historic landmarks, and even a few spooky creatures along the way.
All of this is synched up with lights and music for a fully immersive experience.
Several new displays this year include an animated "Jack" Smith who is working in his workshop and a hive of glowing bees.
The event continues on certain days through Nov. 20.
Organizers expect more than 150,000 people to visit.
