Island Peak is reached by flying to Lukla and walking for about a week via Namche Bazaar and Dingboche to Chhukung. Weather and flight delays are the main logistical risks.
Flight to Lukla
The flight from Kathmandu or Ramechhap takes about half an hour. Departures are in the morning. Baggage is limited, so pack trekking gear in a soft duffel and leave surplus at your Kathmandu hotel.
Lukla to Chhukung
Walk by Phakding, Namche, Tengboche and Dingboche to Chhukung at roughly 4,730 m. Expect five to seven days with a rest day at Namche and another at Dingboche or Chhukung. These rest days are part of the safety plan, not a luxury.
Base camp and high camp
Island Peak Base Camp sits at about 5,100 m, a few hours above Chhukung. Many teams continue to a high camp at around 5,600 m to shorten summit day. See the camp guide.
Return
After the summit you descend to Chhukung and retrace to Lukla in three to four days. Some groups use a helicopter from the Khumbu to save time, though weather can cancel it.
Moving gear and people
Climbing gear is bulky, so decide in Kathmandu what you will hire and what you will bring. Hired boots and crampons are packed in your duffel and carried by porters from Lukla. Keep a day bag with your valuables, sun protection and a warm layer, and let the porters handle the rest.
Costs to expect
Flights, permits, guide fees and gear hire are the major transport-related costs. Compare quotes carefully: some include the Lukla flights and some do not, and some exclude the helicopter. Ask for a written list of what is included.
Buffer days
Keep two spare days in Kathmandu after the return. Flight queues can last more than a day. See the logistics answers.
From Lukla to Chhukhung
After landing at Lukla, the trail follows the Dudh Koshi to Namche, then continues through Tengboche and Dingboche to Chhukhung. This route doubles as acclimatisation, so resist the urge to rush it.
The final approach
From Dingboche the trail rises through Chhukhung at about 4,730 m, then climbs to base camp near 5,100 m. Most teams spend a night or two at Chhukhung to adjust, climb a nearby ridge and practise ropework before moving up.
