The short version: three of the most asked questions, answered in a line each. The rest of the page goes into detail.
- Which night in the 6-day plan carries the most altitude risk? The step from Deurali (about 3,230 m) to Machhapuchhre Base Camp (about 3,700 m) and then Annapurna Base Camp (about 4,130 m) is the main stress.
- How much height should I gain each night above 3,000 metres? Aim for roughly 500 m of sleeping height per night.
- Which symptoms mean I should turn back on the way to the Sanctuary? Worsening headache, vomiting, loss of coordination or breathlessness at rest are reasons to descend.
Which night in the 6-day plan carries the most altitude risk?
The step from Deurali (about 3,230 m) to Machhapuchhre Base Camp (about 3,700 m) and then Annapurna Base Camp (about 4,130 m) is the main stress. Going from Himalaya at about 2,870 m to Machhapuchhre Base Camp takes only two stages, so the climbing is steady with little gentle approach.
How much height should I gain each night above 3,000 metres?
Aim for roughly 500 m of sleeping height per night. Below about 3,000 m most people feel well, but above it the pace matters. Annapurna Base Camp is lower than Everest Base Camp, yet the final climb is steep and fast, and a short plan makes it faster still.
Which symptoms mean I should turn back on the way to the Sanctuary?
Worsening headache, vomiting, loss of coordination or breathlessness at rest are reasons to descend. Poor sleep and mild headaches are common at the base camp, but they should not get worse. Tell your guide about any symptom at once rather than waiting to see if it passes.
Who decides whether the upper valley is safe after snowfall?
Your guide does. The upper Sanctuary has avalanche-prone slopes after heavy snow, mostly in winter and early spring. Guides check the conditions and may delay or turn around, and you should follow their decision even if it costs you the summit-day view you came for.
What insurance should I carry for a quick base camp trip?
Carry a policy that covers trekking above the base camp altitude of about 4,130 m and includes helicopter evacuation. Read the exclusions, keep the policy number on your phone and on paper, and share it with your operator before you leave. A short plan does not reduce the need for cover.
How can I lower my risk if I only have six days?
Sleep at Deurali on the first night above 3,000 m rather than going higher. Start the final day early to avoid afternoon cloud, drink consistently and rest in the afternoon. If you sleep badly at altitude or have not been above 3,000 m before, choose a longer plan.
