When you ponder what to bring with you on an Annapurna Circuit trek or Everest Base Camp trek, you will be limited to 15kg – 33-and-a-third lbs – for the flight to Lukla or Pokhara (although buses have no limit), so it will be something you have thought of much. You will understand why there is such a low weight limit when you catch glimpse of the aeroplane and airport. Clothing is dealt with elsewhere.
For sure, you will see days from one shower to the next, and you are going to perspire. You will have to live with the fact that you are going to smell unwholesome, although it is less bad given that everybody else will smell the same. Toiletries you will require are toilet paper, and plenty of it, because there is precious little chance of finding any at a tea house; wet wipes since the water will be too cold for washing; SPF50 sun cream; deodorant; a razor, if you happen to be male; toothbrush and toothpaste; soap; shampoo; hand sanitiser; and a medical kit. The medical kit should contain surgical tape; plasters; neosporin; nail clippers; imodium; ifuprofen; and diamox. 12 diamox tablets, taken for altitude sickness, will cost around $4 in Kathmandu, much less than the price of a UK prescription. And to go with these, you will want a quick dry towel.
The electronics you will need are an iPad for the uploading of photographs; an iPhone that will even work from time to time; headphones; a camera; and chargers. Taking a solar-powered battery pack instead of a charger will save you money, as electricity must be paid for.
A Steripen purifies water and is a sound addition to your equipment, considering that water purification tablets normally require 30 minutes to take effect and taste none-too-good. You will take a small bag which your porter will carry and a daypack and cover you will carry yourself. There is a call for a pair of water bottles, one of the Nalgene variety for easy Steripen use and one that is Swix style and made of metal which can be used as a hot water bottle at night. Another very useful item is a Camelbak, which sits in your daypack and allows you to hydrate, hands-free. A silk sleep sheet or sleeping bag liner will prevent your bedding from stinking too much. You will feel the need for a headlamp when you visit the toilet in the dead of night or read after lights out. Nighttime toilet visits will be inevitable if you take diamox. You can use playing cards and a book to amuse yourself in the evenings. You are sure to wish to write about your activities, for which you should take a journal and pen.
Finally, energy, granola or chocolate bars will provide you with calories as you hike. Trekking poles are certain to be vital for steep ascents. And you will want a facemask for when the air gets very dusty, as it certainly will.
