A MINI adventure park dubbed Challenge Valley will see scouts test their nerves in bushland at Maryborough Showgrounds over the next week.
An estimated 900 children a day will take part in activities that include abseiling, rock climbing, a flying fox and a specially built ropes course.
The course, built by older scouts and named the Double Helix, requires scouts to first climb through rope tunnels that twist and turn before crawling through thick mud to get to the finish.
Another challenge involves stacking milk crates as high as possible to create a platform for scouts strapped into a harness.
Abseiling scouts must fight for a grip on the shipping containers stacked high to make a wall.
Scouts rotate from the onsite activities to offsite activities such as water sports in Hervey Bay each day.
