Be among the few to have climbed Antarctica’s highest volcano and one of the Volcanic Seven Summits. Join the ultimate mountaineering expedition to Mount Sidley (4285m / 14,058 ft) and stand atop one of the most remote summits on earth.

Sidley is a huge mountain, set on the white expanse of the Polar Ice Sheet. This majestic peak features a 3 mi (5 km) wide caldera and sheer-walled amphitheater, created by an explosive eruption 4.7 million years ago. Blue-ice slopes guard the upper mountain and fantastical snow mushrooms sprout along the upper ridge, leading to the summit.

Mount Sidley was first climbed in 1990 by New Zealander Bill Atkinson.

Day 1: Arrive in Punta Arenas, Chile. Our guide will meet you upon arrival at the airport and take you to our hotel. After settling in, we will conduct a thorough equipment check, and then have a group dinner at one of the many fine restaurants.

Day 2: After breakfast, we attend a pre-flight briefing with our flight operator, and discuss many aspects of the journey to Antarctica. In the afternoon we send our duffel bags to the airport to be checked and packed for departure. We have the late afternoon and evening to explore the city.

Day 3: Depart for Antarctica. We fly approximately 5 hours over the Drake Passage and land at Union Glacier camp. We generally spend 1-2 nights at this camp.

Day 4: Review rope travel, Ice axe arrest, and crevasse rescue techniques.

Day 5: Fly to Mount Sidley base camp, establish base camp.

Days 6-12: Climbing period. Mount Sidley has been climbed by fewer than 10 teams and there is still opportunity for exploring new routes. The mountain offers several interesting options, including a longer, easy ascent from the north side and a steeper climb up the west ridge from the Bennett Saddle. Your guide will assess the options and decide on a route based on the group’s skill and experience.

From base camp to the summit of Mount Sidley involves approximately 7300 ft (2225 m) of elevation gain. You’ll climb alpine-style, setting intermediate camps on the mountain, and carrying all of your food and equipment with you. Although you may use skis lower down on the mountain, most of the climb will be done with crampons.

The slopes of the mountain are wind-blown, with hard packed snow and sections of blue-ice. Gentle slopes near the base give way to steeper terrain higher up.

Summit day offers spectacular views as you follow up the summit ridge along the rim of the caldera. The walls of the Weiss Amphitheater drop steeply away below you and neighboring Mount Waesche may tempt you with its snowy slopes.

As you make your way to the summit ridge, you’ll weave your way between a fantastical maze of snow mushrooms. These massive snow features are formed by wind and moisture depositing rime ice on small obstacles over time.

Following the summit, you’ll return to your high camp, then retrace your steps back to base camp.

Day 13: Fly back to Union Glacier Camp this day.

Day 14: Fly from Union Glacier Camp to Punta Arenas

Day 15: Depart Punta Arenas for home.

Days 16-18: Extra days in case of bad weather or flight delays.
