Knowsley Safari is set to transform into a pumpkin-themed adventure.
The Foot Safari will offer a spooky yet family-friendly experience from October 23 to October 31.
Adding to the fun, one child can enter for free with each full-paying adult during the half-term period.
Families can take part in a pumpkin patch treasure hunt and a haunted garden walk, with pumpkin-themed photo opportunities available between 11am and 4pm each day.
Face painting will be available for an additional charge.
The treasure hunt is aimed at children under 12, who will be given a Halloween-themed map to guide them past ghosts, scarecrows, spiders, and pumpkins.
Their journey will end when they discover a mysterious character with a Halloween treat.
The Oasis Restaurant and Outdoor Food Court will be open for refreshments.
Knowsley Safari's head of visitor operations, Richard Smith, said: "Halloween is one of the most exciting times of the year, a chance for the whole family to take part in some ghoulishly fun activities.
"This year, our Pumpkin Safari Spooktacular is designed to ensure maximum spookiness and fun, as well as great value, with all activities included with the general admission tickets and the kids go free offer runs each day from October 23 until October 31."
Visitors can also head onto the UK's longest safari drive, home to Bactrian camels, southern white rhinos, baboons, African lions, and many other animal species.
The free Safari app can be downloaded to help guests plan their day, providing interesting animal facts and interactive visitor maps.
The Pumpkin Safari Spooktacular is included with a paid admission ticket.
One child, aged up to 15, can enter for free with one full-paying adult.
Tickets start from £22.50 for adults if booked online at least one day in advance.
