I’m a big mountaineering and trekking fan since I did the Everest Base camp. I can tell you that it is the best experience I’ve had in my life. I’ve been to a lot of beautiful and amazing places, but this is just something else.
The best piece of advice I can give you is to go with a reputable USA or Western company. There are a lot of issues with permissions, papers and a lot of stuff to deal with. Also hire a travel insurance that covers Trip Cancellation because sometimes expeditions in Nepal are cancelled and you could lose all your money. It happened to a friend of mine, so spend a bit more in insurance, it’s totally worth it.
If you’re going to Nepal I suppose you will have to deal with altitude. The body reacts in crazy ways to altitude and it’s better to be prepared. I went to Peru and was at an altitude of 15000 feet and when I was in Nepal I still had some issues with altitude. I would suggest you take a lot of Ibuprofen with you. It’s the best way to deal with altitude. Take 600 mg. before ascending and during your whole trip. This does not guarantee you won’t have any issues, but it does alleviate the symptoms. A lot of people take Diamox but I hate it. The side effects are just too much and that drug alone could really ruin your trip. Take it just in case you feel terrible.
You’ll probably be staying in tea houses during your trip and this can be a little…different. Even though people are super hospitable the hygiene standards are different in there. Be prepared to get sick, like really sick from your stomach. Take antibiotics with you, anti-diarrhea, food poisoning meds and antihistamines. There are companies that offer tenting service with chefs and this could avoid getting sick, but it increases the prices by 40 or 50 percent. The thing is that even if you sleep in tents you would still have to eat in tea houses from time to time and believe me, you will get sick. Everyone gets sick.
Also, be prepared for the toilets situation, they can be kind of challenging for someone who is not used to those kinds of toilets.
Buy the best equipment you can, you will need it and you will be really happy that you didn’t skimp on that once you’re in there.
Guess for now this is all. If you need any more advice or have doubts don’t hesitate to contact me. I can give you a lot more info and will be happy to clear any doubt you have
