Mera Peak (6476 m) is classified as a Nepal “trekking peak” — technically the simplest 6000-er in the Himalayas, achievable without fixed lines and rope climbing. It’s popular as a “first 6000-er” for trekkers after EBC or Annapurna. Medically, however, it is still 6476 m with all risks of HAPE, HACE, hypothermia, and glacier crossing. This brief: 18–22 day acclimatization profile, what differs Mera Peak from EBC trekking, 6000-er medical kit.

Mera Peak by the numbers

  • Altitude: 6476 m (Mera Central)
  • Location: Solukhumbu, Nepal, south of Everest
  • Typical length: 18–22 days (from Lukla)
  • Summit success: 70–80% (highest among Nepal 6000-ers)
  • Technical difficulty: PD (peu difficile) — gentle glacier, last 200 m with fixed lines
  • Required permit: NMA (Nepal Mountaineering Association) — ~$250

What differs Mera Peak from EBC trek

  • Higher maximum altitude: 6476 m vs 5643 m (Kala Patthar) — significant HAPE/HACE risk jump
  • Overnight at 5800 m (High Camp) instead of 5364 m (EBC) — longer extreme altitude exposure
  • Summit push on glacier — requires crampons, ice axe, team rope
  • Three nights above 5000 m (Khare 5000, High Camp 5800, possibly Thuli Kharka 4300)
  • Less crowded — trail less popular than EBC, more solitude

Specific medical threats

  • HAPE — elevated risk due to 5800 m overnight (High Camp); ~5–8% of participants
  • HACE in 1–2% of climbers — usually after ignoring AMS signs at Khare (5000 m)
  • Finger frostbite — night/pre-dawn summit push, −15 to −25°C
  • Energy exhaustion — summit day 10–14 h moving, +700 m and −700 m
  • Glacier accidents — rare, but crevasse falls do happen on final stretch to summit

20-day standard acclimatization profile

  • Day 1: Kathmandu → Lukla (2860 m), trek to Chutanga (3100 m)
  • Day 2–4: Over Zatrwa La (4600 m) to Kothe (3700 m), Thuli Kharka (4300 m)
  • Day 5–7: Thangnag (4350 m), acclimatization days
  • Day 8–10: Khare (5000 m), 2 acclimatization nights with rotation to Mera Glacier
  • Day 11: Khare → Mera La (5415 m) → Base Camp (5300 m)
  • Day 12: Base Camp → High Camp (5800 m)
  • Day 13: Summit push (5800 → 6476 → 5800) — 10–14 h
  • Day 14–18: Descent to Lukla
  • Day 19–20: Reserve + flight Lukla → Kathmandu

Frequently asked questions

Mera Peak for post-EBC trekker?

Yes, classic next step after EBC. First 6000-er with minimal technical difficulty (crampons, ice axe, team rope on glacier), but 6476 m altitude means higher AMS/HAPE/HACE risk than EBC 5364 m. Requirements: weekend alpine course minimum, physical fitness (10 km run in 1 h), prophylactic Diamox from 24 h before 4000 m.

Mera Peak vs Island Peak — which to choose?

Mera Peak (6476 m) — easier technically, longer approach, higher summit, higher altitude. Island Peak (6189 m) — harder technically (permanent ice and rock section at summit), shorter approach, lower summit. For first 6000-er after EBC: Mera Peak (simpler technique). For experienced climber: Island Peak (more adrenaline).

Is guide required on Mera Peak?

Since 2023 in Nepal guide is MANDATORY for foreign tourists on all treks and climbs. Cost: guide ~$30/day + porter ~$20/day. On Mera Peak an NMA-qualified guide knows the route, glacier conditions, and has rescue contacts. Solo climbing is illegal.

Pharmacological prophylaxis on Mera Peak?

Standard: acetazolamide 125 mg twice daily from 24 h before 4000 m (Thuli Kharka), continued until descent. For HAPE history: additionally nifedipine retard 20 mg twice daily from Khare (5000 m). Dexamethasone: only in rescue kit (tablets + ampoule), not prophylactically. Kit also must: ibuprofen, paracetamol, azithromycin, loperamide, ORS.

Most common Mera Peak failure causes?

1) Bad summit-day weather (winds, snowstorm) — 15–20% abandonment. 2) AMS/HAPE forcing descent — 10–15%. 3) Physical exhaustion summit day — 5–10%. 4) Finger frostbite halting progress — 3–5%. Total success rate 70–80% (highest among Nepal 6000-ers), mainly thanks to long acclimatization and low technical difficulty.
