In 1989, the Wonders of Life pavilion opened between the Universe of Energy and Horizons. The 100,000 square foot golden geodesic dome contained a variety of exhibits that dealt with health related themes. Fitness Fairgrounds provided guests with a number of interactive exhibits designed to improve one's health and fitness. Guests could ride a stationery bike through a virtual environment (such as the Tournament of Roses parade and even Disneyland), get an analysis of their golf, tennis or baseball swing, and participate in a variety of fun-filled exhibits focusing on the senses of sight, tough and hearing.

The pavilion also featured a number of short shows. "Goofy About Health" tells the story of how Goofy transformed from a slob to a super-goof. "The Making of Me" starred Martin Short in a funny but sensitive portrayal of conception and birth. "Cranium Command" took you inside the mind of a 12 year old boy in a humorous, special-effects filled adventure.

The main attraction at the Wonders of Life pavilion was Body Wars, a simulator ride that took guests on a thrilling journey through the human body.

On January 25, 2004, the Wonders of Life went to a reduced seasonal schedule, opening only during peak periods. The pavilion has not been open at all in recent months and will likely be closing permanently in the near future.
