6. Summit Plummet – USA
This snowy-themed slide at Disney’s Blizzard Beach may look playful, but don’t be fooled — it’s a beast. Towering at 120 feet tall, riders blast down the slope at nearly 60 mph, all while surrounded by fake snow and ski-lodge decor. The straight vertical plunge gives zero time to think — just pure speed from top to bottom. It’s one of the fastest free-fall slides in North America.
