The Everest Base Camp trek elevation profile is one of the most important things to understand before you go — not just the maximum altitude, but how the body gets there, how long it spends at each level, and what the two built-in acclimatisation days actually do physiologically. The highest point is Kala Patthar at 5,545m. The highest overnight is Gorakshep at 5,160m. Furthermore, the trek gains 2,685m from Lukla over 9 trekking days — one of the most gradual and well-managed altitude profiles of any major Himalayan route. Consequently, this guide covers every altitude point with specific numbers, the physiology behind the acclimatisation schedule, and what each threshold above 3,000m actually feels like on the trail.

Everest Base Camp Trek Elevation — Key Altitudes
| Location | Altitude | Role in Itinerary |
|---|---|---|
| Kathmandu | 1,400m | Departure city — international arrival point |
| Lukla | 2,860m | Trek start — immediate altitude jump from Kathmandu on flight |
| Phakding | 2,610m | Day 1 overnight — slightly lower than Lukla, good first night |
| Namche Bazaar | 3,440m | First major hub — two nights for acclimatisation |
| Tengboche | 3,870m | Monastery stop — first night consistently above 3,500m |
| Dingboche | 4,410m | Second acclimatisation base — two nights |
| Nagarjun Hill (acc. hike) | ~5,100m | Day 6 high point — higher than EBC itself |
| Lobuche | 4,940m | Last teahouse before Gorakshep |
| Gorakshep | 5,160m | Highest overnight of the trek — two nights |
| Everest Base Camp | 5,364m | Day trip from Gorakshep — the destination |
| Kala Patthar | 5,545m | Highest point of the trek — pre-dawn Day 9 for Everest sunrise |
The Everest Base Camp trek elevation gain in perspective
Kathmandu sits at 1,400m. Kala Patthar sits at 5,545m. The Everest Base Camp trek elevation gain from city to summit is 4,145m — spread across a flight to Lukla and 9 trekking days. Furthermore, this is deliberately gradual. The two acclimatisation days at Namche (3,440m) and Dingboche (4,410m) are not padding in the itinerary — they are the physiological mechanism that makes the final push to 5,500m possible for people with no prior altitude experience. Consequently, understanding the elevation profile is not just interesting — it directly determines how well the body performs at Gorakshep and Kala Patthar.
Everest Base Camp Trek Elevation — Day-by-Day Altitude Table
| Day | Overnight Location | Overnight Altitude | Daily High Point | Net Gain/Loss |
|---|---|---|---|---|
| Day 1 | Phakding | 2,610m | 2,860m (Lukla) | -250m |
| Day 2 | Namche Bazaar | 3,440m | 3,440m | +830m |
| Day 3 | Namche Bazaar | 3,440m | ~3,900m (acc. hike) | 0m overnight |

The two most important overnight altitudes
Every overnight altitude matters — sleeping high is what drives acclimatisation. However, two overnights define the difficulty of this trek. Gorakshep at 5,160m on Day 8 is the first night above 5,000m. Sleep quality drops noticeably at this altitude. Appetite disappears. The body works harder at rest than it does walking at 3,000m. Furthermore, trekkers reach Kala Patthar at 5,545m before dawn on Day 9 as a day trip from Gorakshep — the first time most have been above 5,500m. Consequently, the quality of the Gorakshep night — how well-hydrated you arrive, how early you sleep, and whether you have followed the acclimatisation schedule — directly determines how you feel at Kala Patthar.
Acclimatisation Science — Why the Schedule Works
The human body begins producing extra red blood cells when it detects lower oxygen above approximately 2,500m. Specifically, this process takes 48–72 hours to produce meaningful results and continues for weeks. The Mountain Hike Nepal EBC itinerary builds in exactly the right stops to exploit this mechanism.
Namche Bazaar (3,440m) — Days 2–3: Two nights at Namche give the body 48 hours of sustained exposure above 3,000m. The Day 3 acclimatisation hike to approximately 3,900m implements “climb high, sleep low” — stimulating higher-altitude adaptation while keeping the sleeping altitude stable. Furthermore, Namche is the last fully-serviced town before the high Khumbu — the right place to spend extra time if any symptoms develop. Consequently, trekkers who complete both Namche nights and the Day 3 hike are physiologically ready for Tengboche and Dingboche.
Dingboche (4,410m) — Days 5–6: Two nights at Dingboche are the most critical preparation for the final push above 5,000m. The Day 6 acclimatisation hike to Nagarjun Hill at approximately 5,100m — higher than Everest Base Camp itself — exposes the body to 5,000m+ as a day trip while sleeping at 4,410m. Furthermore, this is the day that builds the physiological foundation for Gorakshep and Kala Patthar. Consequently, Mountain Hike Nepal treats Day 6 as non-negotiable — it is never shortened, never skipped, and never replaced with a rest day.
What Each Altitude Threshold Feels Like
Numbers on a page do not prepare you for what altitude actually feels like. However, honest descriptions help. Here is an honest description of each threshold on the EBC route.
2,800–3,400m — Lukla to Namche
2,800–3,400m (Lukla to Namche): Most trekkers notice nothing at this range beyond slightly heavier breathing on steep climbs. The Kathmandu to Lukla flight jumps from 1,400m to 2,860m immediately — some trekkers feel a mild headache on the first night at Phakding or Lukla. Drink water, walk slowly, and it passes. Generally, this range causes no real concern.
3,400–4,000m — Namche to Tengboche
3,400–4,000m (Namche to Tengboche): This is where altitude becomes a daily presence. Climbing stairs in the Namche teahouse feels harder than expected. The morning of Day 4 from Namche feels fine — the afternoon arrival at Tengboche (3,870m) feels noticeably different. Furthermore, some trekkers experience disturbed sleep at Tengboche on their first night above 3,500m. Consequently, 3–4 litres of water daily from Namche onward is not optional hydration advice — it is the most effective single prevention measure available.
4,000–5,000m — Dingboche to Lobuche
4,000–5,000m (Dingboche to Lobuche): Above 4,000m, the body operates at 70–80% of sea-level oxygen efficiency. Specifically, every uphill step requires conscious effort. The vegetation disappears and the landscape becomes starkly beautiful — high-altitude desert with glaciers visible above. Furthermore, the Thukla climb above Dingboche to the Everest memorial chortens is the first section where most trekkers genuinely slow to a shuffle pace. Consequently, this is not weakness — it is physiology, and it happens to every trekker regardless of fitness level.
Above 5,000m — Gorakshep, EBC, Kala Patthar
Above 5,000m (Gorakshep, EBC, Kala Patthar): Above 5,000m, the body is managing a meaningful oxygen deficit with every breath. Appetite is low or absent. Sleep disrupts easily and stays shallow. Simple tasks like putting on boots require deliberate effort. Furthermore, the trail between Gorakshep and EBC crosses the Khumbu glacier moraine — boulder terrain that demands full concentration. Consequently, trekkers who arrive at Gorakshep well-hydrated and having followed the acclimatisation schedule describe this altitude as demanding but manageable. Those who have cut corners consistently describe it as genuinely hard.
Everest Base Camp Trek Elevation — AMS Risk by Stage
| Stage | Altitude Range | AMS Risk | Key Prevention |
|---|---|---|---|
| Lukla to Phakding | 2,610–2,860m | Very Low | Stay hydrated — no action needed |
| Namche Bazaar (2 nights) | 3,440m | Low-Moderate | Complete the Day 3 acclimatisation hike |
| Tengboche to Dingboche | 3,870–4,410m | Moderate | 3–4L water daily — report any persistent headache |
| Dingboche acclimatisation | 4,410–5,100m day | Moderate-High | Complete Nagarjun Hill hike — non-negotiable |
| Lobuche to Gorakshep | 4,940–5,160m | High | Move slowly — arrive early — eat and sleep well |
| EBC and Kala Patthar | 5,364–5,545m | High (day visits) | No overnight above 5,160m — return to Gorakshep same day |
Mountain Hike Nepal operates a firm no-ascent-with-AMS policy. If any team member shows active AMS symptoms — persistent headache unresolved by water and paracetamol within 2 hours, nausea, breathlessness at rest, or any loss of coordination — descent begins immediately. Furthermore, Mountain Hike Nepal arranges helicopter rescue and evacuation from any point on the route within hours when needed — your travel insurance covers the cost. Consequently, the AMS protocol is not theoretical — the team applies it every season on real departures and prioritises it above every other consideration.

Frequently Asked Questions
The highest point is Kala Patthar at 5,545m — reached before dawn on Day 9 for the Everest sunrise. Furthermore, trekkers visit Everest Base Camp at 5,364m as a day trip from Gorakshep on Day 8. The highest overnight is Gorakshep at 5,160m. Consequently, the Everest Base Camp trek elevation profile involves two nights above 5,000m — the most altitude-demanding section of the entire expedition.
Everest Base Camp at 5,364m is higher than Mont Blanc (4,808m), higher than the highest point in Africa — Kilimanjaro summit at 5,895m is above it, but EBC is above every peak in Europe, the Americas, and Antarctica below 5,500m. Furthermore, Kala Patthar at 5,545m — the actual high point of this trek — is higher than EBC itself. Consequently, most EBC trekkers stand higher than the summit of Mont Blanc without carrying any technical equipment.
Approximately 2.5 days — the Day 6 acclimatisation hike reaches 5,100m as a day trip, Day 8 visits EBC at 5,364m, the overnight at Gorakshep is at 5,160m, and Day 9 reaches Kala Patthar at 5,545m before descending. Furthermore, reaching above 5,000m on day trips before the Gorakshep overnight follows the “climb high, sleep low” principle the entire itinerary builds around. Consequently, the standard Mountain Hike Nepal itinerary keeps all overnights at or below 5,160m — no higher overnight at any point.
