4. Water Purification
Everyone has a different preference for this, but if saving a few (hundred) bucks is your aim, then invest in some water purification tablets of a reusable water filter prior to your EBC adventure. Some people don’t mind, and will drink the water along the way straight from the taps - but if you’d like to be extra sure about water purity, your options once you’re on the trail will be limited, and expensive.
Since there are no roads to the only villages, the only way for them to get the supplies they sell is to have them carried up on the backs of porters or flown in via helicopter - which means heavy things like water bottles will be very pricey. The higher up you go, the more expensive it gets, with water bottle prices at Gorakshep hitting 450 to 500 rupees (NPR) per bottle.
Easy fix? Bring a filter/purification tablets with you, fill up along the way and drink easy on your trek.
Note: At Gorakshep, there are no faucets or taps to fill up your own bottles. The lodge we stayed at had bottled water for sale and water that they boiled for sale with no other access to water. If you want to avoid this, make sure to fill up extra bottles at Loboche (the village before Gorakshep) and bring them up with you.
5. Tissues
On the subject of expensive things: toilet paper. While most of the lodges provide the standard water/bucket for your bathroom needs, remember it’s ice cold at most lodges given the altitude (literally, at Gorakshep there were ice chunks floating in the water meant to wash your bum).
If this isn’t your cup of tea, a bin is provided for toilet paper waste, but you have to bring your own - which also racks up a pricetag of about 350 to 450 NPR depending on which lodge you’re buying it from.
My suggestion? Bring your own from Kathmandu. If not, many lodges (warning though, not all) have tissues set out on their dining tables in the common room, so if you really find yourself short on cash and toilet paper, you may be lucky enough to find this back-up.
6. Bring Power Banks
Another simple but great way to prepare for EBC. This one is pretty straightforward, but the lodges know people want to take pictures, which means they’re going to need a battery re-charge (which you can have, for a price of course).
Same principle applies here - the higher up you are, the more expensive it is. Battery charging goes for anything from 100 NPR/hour to 400, unless you’re lucky and find free charging somewhere at one of the earlier, lower altitude lodges.
The fix? Bring a couple of power banks, and keep them warm on the high altitude days to keep them from draining quickly.
