Walt Disney World has just shared some new concept art for an upcoming bit of “new magic” coming to Big Thunder Mountain Railroad at Magic Kingdom. Here’s a look!
New Rainbow Caverns Concept Art | Big Thunder Mountain Railroad
In 2026, the iconic Big Thunder Mountain Railroad will reopen with new magic – and today, we have new details to share about what to expect the next time you take to the tracks in search of adventure.
The story of Big Thunder Mountain Railroad dates back to Olden Times, or rather, Golden Times, during the early days of America’s first major gold rush. When Barnabas T. Bullion struck gold in the Big Thunder region, he saw a future full of riches and hustled to start the Big Thunder Mountain Company.
However, them shiny dreams rarely come without a cost, and Bullion quickly found himself in a battle with the forces of nature and in a whole heap of trouble. One day, strange and unexplainable things started happening. Machines failed. Cave-ins shut mines down.
No matter how deep the miners dug into the heart of the mountain, the forces of Big Thunder fought back. And when the attraction reopens next year, the unsuspectin’ passengers who board the runaway trains will learn just how wild the wilderness can get.
In addition to the action and adventure we know and love, Big Thunder Mountain will reopen with new magic for fans to discover.
One such moment comes when the trains rattle their way underground to spectacular natural caverns full of phosphorescent pools, shimmering and illuminating iridescent stalagmites (the ones on the floor) and stalactites (the ones on the ceiling).
The Rainbow Caverns certainly are beautiful… but they ain’t as friendly as they first appear. In fact, that menacing rumble from deep within the mountain may be a sign that we ain’t welcome.
There’s more new magic for guests to discover once Big Thunder Mountain Railroad returns in 2026.
