Island Peak

About the Mountain

Island Peak, known locally as Imja Tse, rises to 20,305 feet (6,189 meters) in the heart of Nepal’s Khumbu region. The mountain is an extension of the ridge descending from Lhotse Shar and rises above the Imja Glacier valley. Surrounded by some of the Himalaya’s most dramatic peaks, it offers sweeping views of the South Face of Lhotse, Ama Dablam, and Makalu.

British explorer Eric Shipton’s party named it Island Peak in 1952 because, when viewed from Dingboche, it appears to rise like an island from a sea of ice. The Nepal Mountaineering Association renamed the peak Imja Tse in 1983, although Island Peak remains its most widely used name. Its climbing history is closely tied to Everest: the southwest summit was first reached in 1953 by Charles Evans, Alfred Gregory, Charles Wylie, Tenzing Norgay, and seven additional Sherpa climbers as part of the British Everest expedition. Tenzing and Edmund Hillary would make the first ascent of Everest just over a month later. The mountain’s slightly higher main summit was first climbed by a Swiss team in 1956.

The journey to Island Peak provides excellent acclimatization as it travels through the Khumbu, including Namche Bazaar, Tengboche, and—weather permitting—Kala Patthar (18,187 ft/5,545 m). Kala Patthar is one of the Himalayas’ finest viewpoints, with an exceptional panorama of Everest, Lhotse, and Nuptse.

Although Island Peak is often described as an introductory Himalayan summit, it is a physically demanding mountaineering objective requiring previous experience with crampons, self-arrest, and glacier travel. The route climbs through rocky alpine terrain before crossing the glacier and ascending a steep headwall on fixed ropes. From there, an exposed ridge leads to the summit, providing an exhilarating finish in one of the world’s most spectacular alpine settings. Island Peak Base Camp itself occupies a strikingly wild position at the head of the Imja Valley, far from the region’s villages.

The Alpine Ascents Way

The Island Peak and Everest Base Camp expedition begins in Kathmandu, where climbers meet their guides before flying into Lukla to begin the trek. Our route follows the classic trail through Namche Bazaar and the monastic community of Tengboche, ascending gradually to allow for careful acclimatization. The trail itself offers a wealth of cultural experiences, as you pass through Buddhist shrines and local teahouses each day of the trip. This is the same trekking route used for our Everest Base Camp Trek— for more details on the trek itself, you can reference the full EBC Trek itinerary.

Our guides are seasoned Himalayan expedition leaders, many of whom have summited Everest and spent years guiding in the region. They work alongside our highly skilled Sherpa guides, whose long-standing partnership with Alpine Ascents brings invaluable knowledge of the mountain, route, and local culture. This exceptional depth of experience is one of the defining features of an Alpine Ascents expedition.

On spring trips, our Island Peak climbers get to spend a night at Everest Base Camp—an opportunity generally reserved only for members of active Everest expeditions, as sleeping at Base Camp is prohibited to general public tourism. Guests stay within our fully established camp alongside climbers preparing for an Everest summit, offering a rare firsthand look into expedition life at the foot of the world’s highest mountain.

Before the Island Peak summit attempt, guides review fixed-line techniques and glacier travel skills with the team at Island Peak Base Camp, preparing climbers for an exhilarating summit day. Throughout the expedition, porters and yaks carry the bulk of the group equipment, allowing climbers to focus their energy on the trail, the culture, and the remarkable mountains around them.

Lodging and the Khumbu Region

For more than three decades, Alpine Ascents has worked closely with Sherpa guides and communities throughout the Khumbu. Most members of our Nepali team have worked with Alpine Ascents for many years, and in some cases generations of families have become part of our extended community. These relationships reach far beyond a single expedition or climbing season and are fundamental to the way we operate in the Himalaya.

Throughout the trekking portion of this trip, we lodge in family-run Sherpa teahouses, offering a rare window into both traditional and monastic Khumbu communities. While accommodations are simple by Western standards, they are balanced by the warmth and support of the families we have partnered with for years.

Before our summit climb, we spend several nights in a fully stocked tent camp at Island Peak Base Camp.
