Crawling Barrel

Outdoor / Individual & Group

What is the Equipment?

Crawling Barrel is a cylindrical tunnel structure mounted securely on a low-height frame. Children crawl through the barrel from one end to the other, exploring movement, balance, and body awareness in a safe and engaging environment.

The barrel provides a tunnel-like experience that encourages crawling, reaching, turning, and coordinated movement. Its enclosed design creates a playful sensory experience while remaining safe and accessible for children of different abilities.

What is the Equipment?

The Inclusive Crawling Barrel was developed to support physical, sensory, cognitive, and emotional development through play.
