He said most visitors spent up to three hours completing each of the seven pathways through the course, at all times attached to a safety wire.
"After that you'd pretty much be worn out," he said.
Mr Olsen said the course took nearly four months to build and come summer would employ five or six full-time staff.
Located near the park's arrival centre, there is room for the Adrenalin Forest to be expanded both in size and the level of challenge it provides.
Full entry is open to those taller than 1.45m while the first two pathways are open to those over 1.3m. Mr Olsen said the course was generally suited to those aged over 10 or 11. Cost of entry to the Adrenalin Forest is $25 for a child and $38 for a adult. Other prices apply for students and younger children.
