Destination
Mount Sidley
A true prize for pioneering adventurers, Antarctica’s highest volcano and one of its most remote peaks awaits: Mount Sidley. Towering above the vast white expanse of Marie Byrd Land, this dormant giant offers a rare opportunity to explore untouched terrain where few have ever set foot. With its dramatic caldera, sweeping icefields, and sense of absolute isolation, Mount Sidley is more than a summit—it’s a bold step into the unknown, perfect for those seeking the ultimate off-the-map experience.
Your Next Volcanic Summit
Step into adventure by summiting Mount Sidley—one of the legendary Volcanic Seven Summits. Standing at 14,058 ft (4285 m), this remote giant promises unrivaled solitude and achievement in one of the planet’s least-traveled corners. Nestled deep within the Polar Ice Sheet. Its explosive past, shaped over 4.7 million years ago, is etched into every ridge and glacier. First climbed in 1990 and pioneered further by ALE’s expert guides in 2010, Mount Sidley remains rich with untouched lines and alpine intrigue. With ALE’s leadership and legacy of exploration, climbers continue to make history on this breathtaking, frozen summit.
