Mine Train Through Nature's Wonderland was a scenic train ride through the American wilderness. One of the last scenes was Rainbow Caverns, a cave themed dark ride scene.
Mine Train Through Nature's Wonderland originally opened as Rainbow Caverns Mine Train in 1956. The exterior scenes were redesigned in in 1960, but since the indoor scene did not change, it does not qualify for a new entry.
Mine Train Through Nature's Wonderland got replaced by the Big Thunder Mountain Railroad-roller coaster in 1979.
