On the Pack Mules - DISNEYLAND '71
Why this attraction did not last that long.
Now in Yesterland.
From an Original GAF Color Transparency by Ross B. Care
When Disneyland opened in July 1955, the Mule Pack was one of the original attractions. When the area through which was mules traveled was enhanced in 1956, the attraction became the Rainbow Ridge Pack Mules. The next expansion was in 1960, resulting in the Pack Mules Through Nature’s Wonderland.
The mule rides ended in 1973.
