Island Peak with Everest Three Passes Trek: Itinerary, Cost & Difficulty

Few adventures in the world of trekking can match the sheer ambition of combining the Everest Three Passes Trek with a summit of Island Peak. This itinerary takes you across three Himalayan passes each standing above 5,300 metres, loops around the world's highest concentration of eight-thousanders, visits Everest Base Camp, and culminates on the summit of a genuine Himalayan peak at 6,189 metres. It is not a casual undertaking but for those who are ready, it is profoundly life-changing.

This guide covers everything you need to plan your 2026 expedition: a realistic cost breakdown, an honest difficulty assessment, permit requirements, and the practical tips that separate a successful summit from a costly retreat.

What Is the Everest Three Passes Trek?

The Everest Three Passes Trek is widely considered the most complete high-altitude trekking experience in the Khumbu region of Nepal. Rather than simply walking to Everest Base Camp and returning the same way, this route forms a grand loop through the entire Sagarmatha National Park by crossing three legendary Himalayan passes.

• Kongma La (5,535 m) is the highest of the three and arguably the most dramatic. The approach involves steep scree and rocky terrain, and the descent drops you directly onto the Khumbu Glacier moraine with Makalu and the Khumbu Icefall filling the horizon.
• Cho La (5,420 m) is the most technically demanding crossing. The final approach is glaciated, requiring crampons in almost every season. The traverse between Dzongla and Dragnag takes six to seven hours and should never be rushed or underestimated.
• Renjo La (5,360 m) is broadly considered the most scenic of the three. From its crest, you see Everest, Lhotse, Makalu, and Cho Oyu rising above the turquoise expanse of Gokyo Lakes, a panorama that many mountaineers rank among the finest on earth.

Together, these three passes form a circuit that touches every major corner of the Khumbu: the Imja Valley, the Gokyo Lakes system, the Thame Valley, and the iconic approach to Everest Base Camp.

Adding Island Peak: Why the Combination Works

Island Peak, known locally as Imja Tse, stands at 6,189 metres above sea level. It was named by the 1952 British Reconnaissance Expedition, which observed it rising like an island from a sea of glacial ice when viewed from the Dingboche valley. It is classified as a trekking peak by the Nepal Mountaineering Association, which means it is accessible to fit, non-professional climbers with the right preparation and a qualified guide.

The reason this combination works so beautifully is acclimatization. After three weeks of sleeping above 4,000 metres, crossing passes above 5,300 metres, and spending a night at Kala Patthar above 5,500 metres, your body is as well-prepared for a 6,000-metre summit as it will ever be without a formal expedition. Trekkers who attempt Island Peak in isolation, arriving from Kathmandu and rushing to the peak within ten days, face a far higher risk of altitude sickness and failure. The Three Passes route builds the perfect physiological foundation.

Complete Cost Breakdown (2026)

Costs depend heavily on whether you book a full guided package through an agency or arrange components independently. The figures below reflect a mid-range guided experience for a solo traveller in 2026.

• Permits and Entry Fees: The Sagarmatha National Park entry permit costs $30 per person. The TIMS (Trekkers' Information Management System) card, under revised 2025 regulations, costs $20. The Island Peak climbing permit issued by the Nepal Mountaineering Association costs $250 in spring (February to May) and $125 in autumn (September to November). Total permit cost: approximately $275-$400 depending on season.
• Guide and Porter: A licensed, English-speaking guide with Island Peak technical experience costs $700–$1,000 for 24 days, including their accommodation, food, and equipment. A porter, often shared between two trekkers, adds another $300–$450. These are not optional costs - they are ethical necessities, and tipping is expected and deserved.
• Flights: A round-trip Kathmandu-Lukla flight costs $280-$360 in 2026. Book early, as peak season flights sell out and prices spike significantly in April and October.
• Accommodation and Food: Teahouse accommodation on the trail averages $8-$15 per night for a basic double room, though prices are higher at altitude. Budget $200–$320 for 20 nights. Food costs $20-$35 per day at altitude more than you might expect, but everything is carried by porter or yak. Budget $480-$840 for meals.
• Climbing Gear Rental: If you do not own crampons, an ice axe, a harness, helmet, and ascender, rental in Kathmandu or Namche runs $80-$150 for the trip.
• Travel Insurance: Non-negotiable. A helicopter evacuation from Island Peak Base Camp costs $6,000-$10,000 without insurance. Your policy must specifically cover helicopter evacuation to 6,500 metres. Budget $150-$300.
• Total Estimated Cost: $2,720–$4,280 per person for a mid-range guided 24-day trip, excluding international flights to Kathmandu. Group packages through a reputable agency can bring this down to $2,200–$2,800 for groups of four or more.

Difficulty: An Honest Assessment

This is a Grade 5 Strenuous/Technical itinerary. It is not suitable for first-time trekkers, those without prior high-altitude experience, or anyone who has not spent meaningful time training in the months before departure.

You will spend seven or more nights above 5,000 metres. You will carry a 6-8 kg daypack for up to nine hours daily on pass days. You will climb a 70-degree ice headwall at 6,000 metres in sub-zero darkness. The combined distance exceeds 180 kilometres over terrain that is rocky, glaciated, steep, and occasionally exposed.

That said, this route is completed every year by hundreds of trekkers who are not professional mountaineers. The key ingredients are: prior high-altitude experience (at least one trek above 4,500 m), a genuine aerobic fitness base built over six months of training, a willingness to acclimatize properly and not rush, and a qualified, experienced guide.

Acute Mountain Sickness remains the primary reason trekkers fail to complete this route. Know the symptoms of persistent headache, nausea, loss of appetite, dizziness, and confusion. If symptoms worsen at any altitude, descend immediately. No summit, no view, no pride is worth your life.

Best Time to Go in 2026/27

• Spring (mid-March to late May) is the premier season. Skies are clear, days are warm, and the trail is at its busiest particularly around Everest Base Camp, where spring expedition teams are active. The Island Peak permit costs more in spring but conditions on the summit headwall are generally most stable in April and early May.
• Autumn (late September to mid-November) is the second-best season and many experienced trekkers prefer it. The post-monsoon air is exceptionally clear, the trail is quieter, and the Island Peak permit is half the spring price. Temperatures drop faster in November and the passes may see early snowfall.
• Avoid monsoon (June-August) and deep winter (December-February) for this specific route. Monsoon creates dangerous trail conditions and obscures all mountain views. Winter closes the passes with ice and brings extreme cold.

Permits Required

You need three separate permits for this itinerary, all processed in Kathmandu before you fly to Lukla:

• The Sagarmatha National Park Permit ($30) is required for all trekkers entering the Everest region and is obtained at the NMA or through your agency.
• The TIMS Card ($20) is mandatory for all foreign trekkers in Nepal and is issued at the Nepal Tourism Board office in Thamel.
• The Island Peak Climbing Permit ($125-$250 depending on season) is issued by the Nepal Mountaineering Association on New Road, Kathmandu. Bring passport photos, passport copies, and payment in cash or by bank transfer. Allow one to two full days for processing.

Conclusion

The Island Peak and Everest Three Passes Trek is not a trip you stumble into. It demands preparation, investment, respect for the mountains, and a genuine love for being tested at altitude. But for those who commit to it fully, it delivers experiences that no other trek on earth quite replicates the frozen silence of a pre-dawn summit climb, the emerald gleam of Gokyo Lakes from a 5,360-metre crest, the surreal drama of Everest Base Camp in spring, and the moment you plant your feet on a 6,000-metre summit and watch the Himalayan giants glow orange in the morning light.
