How Much to Carry
A rough baseline is 0.5 litres per hour of moderate hiking in cool weather. Add 25–50% for heat, heavy packs, or sustained climbs above 800 metres.
Trail Tips
- Drink regularly — do not wait until thirsty.
- Add electrolytes on sweaty days to prevent cramping.
- Plan water sources on your map before departure.
- In autumn, streams run lower — carry extra between known sources.
- Monitor urine colour: pale yellow is the goal.
Gear
- Two 1-litre soft bottles balance weight better than one rigid bottle.
- Insulated sleeve slows freezing in shoulder season.
- Filter or tablets if refilling from wild sources.
