There are many organized trekkings that will take care of everything you need. They will find a good guide, porters, they will carry your tents, prepare your meals and make your life easier. But we chose to do it by our own. This is an option that gives you more freedom. All you need is a trekking permit and a guide or porter. If you are alone you can do the trekking too. You’ll meet many trekkers along the way, so that’s not a problem.
