Overview
- Walt Disney Imagineering announced the timing on Good Morning America, confirming a spring 2026 return for the Magic Kingdom attraction.
- Executive producer Wyatt Winter said the relaunch features all-new trains and refreshed animatronics, with long-dormant effects brought back online.
- A new underground sequence inspired by Rainbow Caverns will send riders through a cavern glowing with phosphorescent pools and iridescent stalactites and stalagmites.
- The updated narrative follows tycoon Barnabas T. Bullion as the mountain resists his gold‑rush ambitions, causing breakdowns and collapses across the mines.
- Disney teases a menacing rumble inside the cavern and describes the work as a mountain‑top to cavern‑deep refurbishment that preserves the classic thrills with expanded detail.
