Remember, the Everest base camp trek is a high-altitude trek, you should have basic knowledge about the packing list according to season.
Don’t forget to carry enough extra socks. Because you need some spare socks for the reason that you don’t have to trek with wet feet. And make sure you have other changing clothes after your arrival at the lodge, so you don’t have to sit around in the damp clothes. Light woolen merino clothes are perfect to keep you warm even if you are wet.
Another is that it’s a good idea to bring your own sleeping bag for the Everest base camp trek. Although most tea houses provide adequate blankets, they are not always clean. Therefore, it is recommended to carry them by yourself. As a result, I hope that this post will assist you in making decisions and preparing.
The EBC Trek Packing List for September is as follows:
Backpack: A backpack with a capacity of 50 to 60 liters is highly suggested. Make sure it’s appropriate for your body type and read reviews online before purchasing. You may like to read more about the backpacking for the Everest trek.
Hiking or Trekking Boots: It’s critical to invest in a pair of hiking boots that fit properly. Ankle boots are a great choice. Read on for more information about boots for the Everest Trek.

Rain Jacket: It must be wind and rain protection and can also utilize during the day. Detachable layers are especially useful.
Flip Flop or light Shoes: After a long hour of trek in hiking boot, you may require light weight flip flop or light shoes to change & wear in the lodges. Especially in late afternoon or in the morning.
Micro Spikes: If you’re travelling over one of three high passes, micro spikes are good. On slick surfaces, these light spikes are useful.
Trekking Poles: However, it is always useful to use on more difficult up and down paths. Purchasing a pole is the best and most cost-effective option.
Water Bottle & Purifier: UV filters, like the SteriPen, and also purifying drops and tablets, are effective. If using drops or tablets, bring your own non-plastic bottle.
Sunglasses: To protect yourself from UV rays, make sure they’re polarized.

Gloves: The best gloves are those that are waterproof. It’s even better if you can get ones with detachable layers.

Nepal Festival & Events in September
Indra Jatra (Procession of King of the Gods): This eight-day festival formally begins on the twelfth day of the waxing moon in September. Indra Jatra is Kathmandu’s largest religious street festivals in Nepal.
This eight-day event is known as Yen Ya and is predominantly observed by the Newar populations. Indra, the Hindu god of rain and heaven, is honored throughout the event. Indra Jatra, on the other hand, is a festival that is followed by both Hindu and Buddhist believers. Basantapur, or Kathmandu Durbar Square, is the focal point of the celebrations.
Kumari Jatra (Chariot procession of Living Goddess): Kumari is worshipped in grand manner in the occasion. Kumari Jatra is a festival in which the living gods Ganesh and Bhairav, as well as goddess Kumari, are drawn through the city in chariots. She steps out of Kumari Ghar, from her house in the square, on this day. The chariots are carried from Basantapur to other parts of the city so that people can see the event and worshipped.
Dashain Festival: Dashain, Nepal’s most important yearly event, occurs in late September and some years, early October. Dashain is predominantly a Hindu celebration and is not much celebrated in the Everest region due to its Tibetan Buddhist influence. But, Dashain is widely observed in the hilly & Terai region by other Nepali ethnic groups.
It is crucial to arrive a day early in Kathmandu before the Dashain celebration day. At this time, much of the city closes down, fewer restaurants and shops open, and taxis are harder to get until afternoon. Remember, Dashain festival is like Christmas day in American & Western countries.
