Porters will carry your expedition pack up to 30lbs, so you will only need to carry a daypack. This should not weigh more than 10% of your body weight AT MOST. Bear in mind that every litre of water weighs 2.2lbs, and you will be carrying a minimum of 3Ls/water at a time. You are welcome to bring your favourite snacks with you, and don’t forget sunscreen, your rain gear and any photography equipment you wish to carry.
