Lilidorei was conceived by the Duchess of Northumberland and has received funding from the Borderlands Inclusive Growth Deal.
The £15m project has created 50 new jobs and will be an all year round destination for the region.
The attraction is set around three towers aligned to a mythical theme conceived as part of an Elf Kingdom.
Visitors will be able to explore adventure pathways, catwalks and tunnel slides, as well as a range of roofed and elevated structures.
The play area is imaginative, complex and dynamic, aiming to challenge children and adults alike, inspiring them as they investigate and have fun.
