You will need to carry a minimum of 3 litres of water on you. There are many places to fill water bottles along the track. Your porters will advise the best places to fill up your water bottles. The furthest you will walk between water is approximately 4 hours.
It is essential that you take electrolytes with you. We highly recommend our own Trek Fuel which can be bought via Kokoda Spirit at https://www.kokodaspirit.com.au/booknow/trek-fuel/
Put electrolytes in your water (separate bottle), every 3rd litre, it prevents dehydration due to high perspiration losses due to exertion and high humidity. Dehydration, overheating and hyponatremia can become major issues on the track.
It is very important to keep drinking fluids and utilising salt and electrolyte replacements on the Track. Due to the higher level of activity, temperature, and humidity you will tend to sweat more. With the increased fluid intake and sweating you also tend to flush out of your system essential minerals, salts etc.
Electrolytes: If unsure please discuss with your doctor.
Water purifying tablets or some form of water purification must be taken as a precaution. The water is generally very good along the Track but always check with the Trek Master or Trek Leader about the quality of the water.
With the different environments, conditions, food, and water, upset stomachs, vomiting and diarrhea can occur. Please ensure you bring adequate medication.
