Ground has broken on Hawaiian Falls' sixth leisure facility, in Tarrant County, Texas, marking the company's first combination adventure park and waterpark.

Pegged to open on Memorial Day weekend in May next year, the new venture will employ more than 300 seasonal workers throughout the summer and 100 full-time employees for the adventure park and conference centre.

The $13m attraction is expected to draw more than 300,000 guests a year and will include a 20,000sq.ft indoor family arcade, private birthday party rooms and a restaurant.

The waterpark will feature a football field-sized wave pool, a 10,000sq.foot activity pool with a floating water obstacle course, splash pads and water walks, a 1,000ft-long river with rapids and fountains, and multi-slide towers featuring speed slides, tube slides and a multi-lane mat racer slide.

The adventure park, open year-round, will feature multi-level ropes courses, adventure trail climbing nets, a military-style obstacle course, 60ft-high climbing and rappelling walls, a six-story free fall attraction and 500ft-long zip lines.

The Aloha Conference Centre will accommodate up to 400 people for dining or up to 1,000 people theatre-style for meetings, conferences and team building events year-round.
