Fantasy Island will end its 2011 season with a twelve-hour opening and £5 unlimited ride wristband offer on 29 October.
The Lincolnshire amusement park will also hold fireworks and a bonfire in the car park opposite the site.
Rides will run well into darkness, operating from 10am until 10pm on the day.
The event is being dubbed the ‘Halloween Extravaganza’, and is set to feature a number of Halloween-themed events.
Wristbands can be purchased on the day with no need for advance booking.
