Useful tips for trekking and expedition
Having a metal bottle can fill it with hot water in the evening before going to bed and put in the bottom of the down like hot water bottle to keep hot little feet.
Putting a cap, heat losses are largely by the head
The night in tents
Overnight to urinate without leaving the tent take a bottle with a wide neck that you will easily find in Kathmandu.
Take a plastic bag like a 30-liter trash bag to put snow in to make water without having to leave the tent.
On the trails
On the trekking paths always park on the wall side when crossing caravans of yaks, horses or mules. For the Yaks the path they follow is theirs, it's up to the others to push themselves.
Camera - photos
If it is cold put the camera or camera batteries warm on you during the day and at the bottom of the sleeping bag at night. If you shoot with a smartphone put it in the sleeping bag at night.
At the airport: memory cards are insensitive to X-rays. X-ray machines are treadmills. On the other hand, magnetic sensing gantries and magnetometers to control people generate magnetic fields that can erase your data on the cards. So for more security do not keep them on you when switching to a gantry or magnetometer control. Leave them with your belongings on the treadmill.
Finally, SD and micro SD cards are very suitable for low temperatures down to -25 °.
Take multiple memory cards of 16 or 32 GB rather than 64 or 128 GB. In case of problems or loss of a card you will not lose all your photos or videos.
Having an electrician scotch roll - serves everything. Have some clothes pegs and string - always useful for drying clothes.
Storage in your backpack
In your backpack put your stuff in a big plastic bag like "solid garbage bag" to protect them from dust and rain.
Storage in your big bag
In your big bag (the one you give to the bearers) you can arrange your stuff by putting them in storage pockets of different colors to closure.
For example, a red for the upper body, in another black lower body, in a 3rd orange gloves, hats etc. This is very convenient to quickly find what you are looking for.
During the trek after a short stop
When leaving, always look behind you if you have forgotten anything.
At camp or lodge
Have a pair of Crocs sandals or equivalent not heavy and very comfortable at camp or lodge after a good day trek or CB expedition.
Keeping them in the backpack during the trek makes it easy to cross rivers.
Treks with pass of pass to more than 5000 m
We advise you to take a real pair of rigid-soled mountain shoes as well as a pair of lightweight aluminum cleats. In case of snowfall and icy passages it will be very useful.
In trek peak and expedition on the day of the ascent or in expe during climbs in the high altitude camps always have a pair of gloves or mittens of relief on oneself to put under the polar to have it well warm.
In the high altitude camps
In expedition altitude camps put the gas bottles at the bottom of the sleeping bag to keep them warm.
Heaters useful on the day of the climb for a trek peak and of course on expedition. But beware it happens that the heat trigger system does not trigger and in this case it is the opposite effect that occurs. The foot is compressed and the blood circulates less well therefore risk of frostbite. So if you do not feel the heat it is better to remove the heater from the shoe.
Food races warm on you on the day of the summit (too hard with the cold). You buy some in Kathmandu.
Use a "meat bag" inside the sleeping bag to avoid soiling the down but above all increases the comfort temperature by a few degrees.
Have silk under gloves very useful at altitude to take pictures when it's cold and you put the gloves on. In general, avoid bare skin contact with metal.
When there are no other solutions for the toilet to take baby wipes this can help. You can buy them in Kathmandu
Think of the essential oil "tea tree" for fungal infections and also as a deodorant. And again at the bottom of the shoes to destroy the smells and the fauna.
For your international flight to Nepal
If you can, plan a company that offers an arrival in Kathmandu early in the morning. This allows you to have all the afternoon in addition to the free day in Kathmandu to visit the city.
Always if you can take a single company between leaving your country and Nepal. This is much simpler in case of baggage loss (if you have used the services of 2 or more companies they are sending you the 'ball' - this is not specific to Nepal).
Also, if you have a flight that arrives in Nepal in the early morning and many companies have several flights a day on Kathmandu, your luggage can arrive on the next flight so just a few hours late.
Finally for your international return flight if you can choose a departure from Nepal late afternoon or better in the early evening. This can be useful if at the end of your trek return to Kathmandu by plane is delayed or postponed by one day (this is only valid for treks whose return is by plane).
