The rise in visitors was boosted by a £2.5m expansion of Thomas Land at the start of 2015, welcoming a host of new rides and attractions.
Chief executive, Colin Bryan, said: “Last year was a truly momentous year for the Bryan family and all of the staff here and we’re so pleased to have been able to provide so many families with lasting memories.
“We always want to go above and beyond to make sure every season is better than the last for our visitors and in 2015 year we did just that.
“Now we’re really looking forward to another fantastic year in 2016.”
The season also ended with another record breaking attendance during its Magical Christmas event with a 34% increase in guests from 2014.
