Who We Are

Challenge Design Innovations (CDI) was born 40 years ago when we built company founder, Jim Wall, built his 1st ropes course and zip line with the idea that quality products and services are built upon quality relationships.

Jim Wall built a ropes course at San Lee Park in Sanford NC in 1980. By 1987 he had started a company, Walls Outdoor Associates, that would take a few twisting paths to become CDI.

Today, the company owned by Corey Wall (Jim's son) and employs a staff with decades of experience.

Here, you can feel confident that you are working with leaders in the industry, and you will feel at ease because you know we have your best interests at heart.
