The Island Peak Climbing itinerary runs 15 days, Kathmandu to Kathmandu, with the first nine days following the same route and acclimatization schedule as our standard Everest Base Camp Trek before turning off toward Chukkung, Island Peak Base Camp, and the summit push itself. This guide walks through all 15 days at the level of detail that actually matters — altitude, walking hours, and where you sleep — not a marketing summary of them.
You spend only one night of the whole trip above 5,000m, and you reach the summit in a single push with no separate High Camp. Where the real difficulty concentrates, and why, comes up further down.

Day-by-Day: The Full 15-Day Route
Day 1 — Kathmandu to Lukla to Phakding (2,610m)
A short, scenic flight from Kathmandu drops you into Lukla’s mountain airstrip, one of the more memorable landings in trekking. From there it’s a gentle afternoon walk down to Phakding on the Dudh Koshi, 3 to 4 hours, a good warm-up before the climbing starts in earnest.
Day 2 — Phakding to Namche Bazaar (3,440m)
The trail crosses several suspension bridges over the Dudh Koshi before a steep climb into Namche, the Khumbu’s unofficial capital. First real views of the high peaks also open up on the approach, weather permitting. Five to six hours.
Day 3 — Namche Bazaar: Acclimatization Day (3,440m)
A short acclimatization hike up toward the Everest View Hotel gives your body a controlled dose of extra altitude before descending back to sleep at Namche — climb high, sleep low, the same rhythm every high-altitude itinerary depends on. Three to four hours.
Day 4 — Namche to Tengboche to Debuche (3,820m)
The trail climbs to Tengboche, home to the Khumbu’s largest monastery and some of the best Everest and Ama Dablam views on the entire route, before a short drop to the quieter village of Debuche for the night. Five to six hours.
Day 5 — Debuche to Dingboche (4,410m)
The forest thins out as the trail climbs into the open Imja Valley. From there, Dingboche sits well above the treeline, with your first proper views of Lhotse and Island Peak itself in the distance. Five to six hours.
Day 6 — Dingboche: Acclimatization Day, Nagarjun Hill (~5,000m)
A second acclimatization hike, this time up Nagarjun Hill above Dingboche. The climb is steep but short, and the panorama at the top — Makalu, Lhotse, and the Imja Valley spread out below — is one of the best viewpoints on the route for the effort involved. Three to four hours.
Day 7 — Dingboche to Lobuche (4,910m)
The trail climbs along a ridge past the memorials to climbers lost on Everest, a sobering stretch, before dropping into Lobuche. The air is noticeably thinner here, and this is where the trip’s demands start to build. Five hours.
Day 8 — Lobuche to Gorak Shep to Everest Base Camp to Kala Patthar and Back to Lobuche (5,644m)
This is the longest, hardest trekking day of the trip — be honest with yourself about that going in. You trek to Gorak Shep, continue to Everest Base Camp (5,364m) and back, then climb Kala Patthar (5,644m) for the best close-up view of Everest’s summit pyramid on the route, before returning all the way down to Lobuche for the night. Ten to eleven hours total. Pace yourself and drink more water than feels necessary — this day asks a lot before the technical climbing even begins.
Day 9 — Lobuche to Chukkung (4,730m)
The route leaves the main EBC trail behind and turns south into the quieter Chukkung valley. Island Peak also comes into full view for the first time, and the crowds of the main trail thin out noticeably. Five to six hours.
Day 10 — Chukkung to Island Peak Base Camp (~5,200m)
A short but steady climb brings you to Base Camp, where tents replace teahouses for the rest of the climb. Three to four hours. Afterward, you spend the afternoon on technical training with your climbing Sherpa — crampon technique, ice axe use, and practicing on the fixed ropes you’ll rely on the next day.
Day 11 — Summit Push to Island Peak (6,189m) and Descend to Chukkung
An early start, often before 2am, for the summit push. The route crosses glacier terrain and a crevasse — bridged by a fixed ladder — before a steep headwall on fixed ropes leads to the summit ridge. Ten to twelve hours door to door. After the summit, you descend the same way and continue all the way down to Chukkung the same day, back in a teahouse bed that night — the previous night at Base Camp was the only night of the whole trip spent above 5,000m.
Day 12 — Contingency Day, Chukkung
A built-in buffer day in case summit day needs to move for weather. If it isn’t needed, it’s a genuinely restful day before the descent begins — your legs will likely be grateful for it either way.
Day 13 — Chukkung to Namche Bazaar (3,440m)
A long descending day back through Tengboche and down to Namche. The air thickens noticeably with every hour, and it’s usually the first day of the trip that feels genuinely easy to breathe. Six to seven hours.
Day 14 — Namche Bazaar to Lukla (2,860m)
The final trekking day retraces the route back to Lukla. Six to seven hours. A last night in the mountains before the flight out the next morning.
Day 15 — Fly Lukla to Kathmandu
A morning flight back to Kathmandu, 35 minutes. Build 2 to 3 buffer days into your travel plans beyond this point — Lukla flights are the single most common source of delay on this trip, and your international departure shouldn’t be booked tighter than that risk allows.
How This Itinerary Is Built
The first nine days of this itinerary follow the same route and pacing as our standard Everest Base Camp Trek — same altitudes, same acclimatization schedule (Namche on Day 3, Dingboche on Day 6), same trekking times. Where the two trips actually diverge is Day 9 onward: instead of finishing at Base Camp and flying home, this itinerary turns south to Chukkung, adds the technical training afternoon at Island Peak Base Camp, the summit push itself, and a built-in contingency day. That’s the entire difficulty gap between the two trips, concentrated into four days.
You spend only one night of the whole trip above 5,000m — Island Peak Base Camp on Day 10 — fewer high-altitude nights than most Nepal climbing itineraries carry. Day 11’s summit push reaches 6,189m but doesn’t stay there; you’re back down to Chukkung (4,730m) the same night. Day 12 exists specifically to absorb a weather delay on summit day without forcing a rushed descent — if it isn’t needed, nothing else in the schedule has to compress.
Frequently Asked Questions
Two dedicated acclimatization days on the trekking portion — Namche Bazaar on Day 3 and Dingboche on Day 6 — plus Day 8’s long EBC and Kala Patthar detour, which adds extra altitude exposure before Base Camp even though it isn’t a rest day itself. Day 12, the contingency day at Chukkung, is a weather buffer for the summit push, not an acclimatization day.
No. We schedule a rest day to help the body acclimatize before an altitude gain; Day 12 exists purely to absorb a weather delay on summit day, since Island Peak’s summit push can’t safely happen in poor visibility or high wind. If summit day goes to plan on Day 11, Day 12 becomes a genuine rest day by default — but we build it into the schedule as a weather buffer first.
We don’t recommend cutting either acclimatization day or the contingency day. If Day 12 genuinely isn’t used, because summit day went to plan and the weather forecast for Day 13 onward looks stable, it’s possible to move the flight home earlier — but that’s a decision made on the ground with your guide, not something to plan for in advance.
