Mega Marble Junior Radical Wet/Dry Obstacle Course Hire Sydney

The Mega Marble Junior Radical Obstacle Course is a spectacular wet or dry inflatable. The size is 11m L x 5m W x 5m H and it can cater to small back yard party groups. It is also great for large groups at fetes, festivals, sports and school events.

This obstacle course is a wet or dry course. This means it can serve as a water obstacle course in summer as well as a dry one in cooler months. It’s design includes slides, pop ups, tunnels and ladders. This is a very popular course because it can fit in most average sized backyards or play areas. If you want it to be a wet course we will need access to a tap.

If you are looking for a slightly smaller dry obstacle course try the Radical Junior Obstacle Course.
