Mera Peak (6,476 m) and Island Peak, also known as Imja Tse (6,189 m), are two of the most popular trekking peaks in Nepal, both classified by the Nepal Mountaineering Association as “Group B” climbing peaks.

Mera Peak is the highest trekking peak in Nepal, famous for its relatively non-technical ascent and breathtaking 360° summit panorama that includes Everest, Lhotse, Makalu, Cho Oyu, and even Kangchenjunga on a clear day. Mera demands more days due to its remote approach and higher altitude.

Island Peak, located in the Everest region, offers a shorter expedition that combines perfectly with the Everest Base Camp trek, making it ideal for trekkers who want to add a climbing challenge. Island Peak requires more technical climbing skills, including fixed rope, crampon, and ice axe use on its steep headwall and narrow summit ridge. Its prime selling point is the spectacular close-up views of Ama Dablam, Lhotse and Everest because the approach sits inside Sagarmatha National Park.

Both climbs require official climbing permits and national park entry fees, with costs ranging from USD 1,500–3,000 depending on duration, logistics, and group size.

Island Peak usually requires more short, technical scrambling and fixed-rope work on a steep headwall and narrow summit ridge; clients are often roped for the final section. Mera Peak’s standard routes involve long glacier walking and crevasse awareness, and recent changes to the summit block can add a brief PD (not-very-hard) technical section — but most of Mera is less steep and more sustained altitude than technical climbing. In short: Island Peak is punchy-technical; Mera is longer and more altitude-intense.

Spring (Mar–May) and Autumn (Sep–Nov) are the prime windows for both peaks — stable weather, clearer skies and calmer winds. Winter is possible for very experienced, cold-tolerant teams; monsoon (June–Aug) brings heavy snow/avalanches and low visibility so it’s usually avoided.

Both peaks require official peak-climbing permits handled through a registered Nepali operator like us Raj Bala Treks & Expedition. Island Peak sits inside Sagarmatha National Park (additional park entry and TIMS/trekking permits apply on the Everest route). Mera Peak also needs an NMA (Nepal Mountaineering Association) permit and paperwork submitted by your operator.

Note: Nepal has been updating permit fees and regulations in recent seasons — always confirm current fees with your operator before booking.

Island Peak packages (including Lukla flights from Kathmandu, guide, staff, permits, basic group climbing gear) commonly fall in a moderate range because many teams combine the climb with Everest Base Camp treks — you will often see packages from ~USD 1,500–2,500, depending on group size and service level.

Mera Peak is typically more expensive because it’s more remote (longer expedition length, extra logistics) — typical packages are ~USD 2,000–3,000+. Exact numbers shift with fuel/flight costs, permit changes, and your operator’s inclusions.

Island Peak (classic) — 12–16 days from Kathmandu: fly to Lukla → trek via Namche, Tengboche → EBC/Chukhung area → Chukhung Base Camp → High Camp → summit → return to Lukla → Kathmandu. Summit push often done as an early-morning ascent from High Camp.

Mera Peak (classic) — 16–21 days: Kathmandu → Lukla (or Phaplu for some routes) → trek into Hinku/Hongu valleys → Mera Base Camp → Amphu Lapcha / High Camp approach depending on route → summit → back out. Mera itineraries require additional acclimatization days and more trekking days to reach the base of the peak.

Mera Peak: arguably the best summit panorama of any trekking peak — summit views of five 8000-m mountains in one sweep (Everest, Lhotse, Makalu, Cho Oyu, Kangchenjunga) on clear days. If your primary goal is a big-mountain, cinematic panorama, Mera often wins.

Island Peak: dominates the Chukhung/Imja valley skyline and places you right in the Everest region’s iconic scenery — Ama Dablam, Lhotse, Nuptse and Everest are visually dominant from the final ridge. The narrow summit ridge makes for dramatic summit photos.

Choose Island Peak if: you want a shorter itinerary, you are already doing the Everest Base Camp trek or want to combine them, you don’t mind a short technical headwall and fixed ropes, and you prefer a well-trodden classic.

Choose Mera Peak if: you want a higher summit and extraordinary panoramic views, are comfortable with longer trekking days and remote logistics, and want to test sustained high-altitude performance rather than short technical climbing.

Altitude is the single greatest risk: both peaks exceed 6,000 m where AMS (acute mountain sickness), HAPE and HACE are real concerns. Proper acclimatization — gradual gain, rest days, hydration, and turning back early if symptoms appear — is essential. Both peaks require experienced local guides; Island Peak usually mandates a rope-trained guide for the summit section. Carry a reliable satellite/phone emergency plan and ensure insurance covers high-altitude rescue/evacuation.

Insulated down jacket, double-layer sleeping bag rated to −20°C, crampons, ice axe (usually provided by operator but bring your own if you prefer), harness, helmet, small daypack for summit push, sturdy 6000-m boots, goggles, sun protection, headlamp, personal first-aid + altitude meds (acetazolamide if prescribed), water purification. Operators typically supply group ropes, tents, and some technical gear.

3 months out: build aerobic endurance (hiking with 10–15 kg packs), stair/climbing intervals, and specific leg strength. Add a few long weekend hikes at 4–5 hours with heavy packs.

2–4 weeks before: taper training, focus on sleep, nutrition and acclimatization practice (if possible). Consider a pre-expedition hypoxic course or a guided lower-altitude trek to see how you respond to altitude.

On trek: keep daily elevation gain moderate, avoid alcohol, eat high-carb meals and sip fluids continuously.
