Trekking Snacks That Actually Work at Altitude
What to carry above 3,000m, what fails, and why appetite disappears exactly when you need calories most.
The cruel arithmetic of high-altitude trekking is that your energy requirement climbs while your appetite collapses. Above 3,500m most people find they simply do not want to eat, which is precisely when under-fuelling becomes dangerous.
What fails on the trail
- Chocolate — becomes unmanageable in the sun, rock-hard in the cold
- Fresh fruit — heavy, bruises, mostly water you are already carrying
- Energy bars — most people find them cloying by day three
- Anything requiring water to prepare, if you are rationing
Why dried fruit holds up
It is calorie-dense at roughly 240–260 kcal per 100g, it does not melt or freeze into a brick, it survives being crushed in a pack, and — this is the part that matters at altitude — it is acidic and sweet enough to eat when nothing else appeals.
A workable daily ration
Around 150g of mixed dried fruit per trekking day, split into four small portions rather than two large ones. Small and frequent is much easier to get down than sitting with a full meal you do not want.
- Morning: banana chips with tea — potassium before you start climbing
- Mid-morning: mango or pineapple, roughly 30g
- Afternoon: citrus slices, which reliably work when nothing else does
- Evening: berry mix, which does not interfere with sleep the way caffeine does
Keep it in the lid pocket, not deep in the pack. A snack you have to stop and dig for is a snack you will skip.
