June 26, 1956 – The Rainbow Ridge Pack Mules Attraction Opens in Disneyland
On June 26, 1956, the Rainbow Ridge Pack Mules attraction opened in Disneyland’s Frontierland. It was the second incarnation of a mule pack ride through Frontierland, with the Mule Pack attraction open before it from 1955 to 1956. Guests rode through Frontierland’s landscape on a ten-minute ride with a team of sometimes rather temperamental mules. The attraction ended on October 2, 1959, but reopened as Pack Mules Through Nature’s Wonderland in 1960.
