>>2635537>>2635537>>2635462>How much cash should I take with me?However much you'll need during the trek and a little extra for emergencies. Some of the villages accept card, most don't. As for ATMs, using my most recent trip as an example there's an ATM in Namche Bazar which we passed on day 5 of the trip and then that was it until we passed through Namche again on day 20. And if you're unlucky the ATM will have run out of money or refuses your card. Try to bring both visa and mastercard if possible.
>Is transportation safe?What? Too good for runways with a cliff at one end, a mountainside on the other and 25 degree slope in between?
Honestly, I'm not sure that the buses are that much safer. Roads in Nepal are narrow, winding, invariably have a cliff on one side and road rules are more of a suggestion.
Theft is unlikely but if you're travelling on an overnight bus you'll want to be able to lock every compartment of your pack, and bring a cable so you can lock it to the bus.
>And finally, do you think it could be reasonable to arrange for a guide/porters to take me to other trails to look for snow leopards?I'm sure it's possible but I don't have any advice as to how. A trip like that will definitely be more expensive, especially if you end up needing to go to the more remote parts of the country. If you're staying in tents, carrying in food/cooking equipment, etc then prices rise significantly vs staying in teahouses. If your expedition is organised by a foreign company employing foreign guides or naturalists (which may be necessary to have a good chance at spotting something as elusive as a snow leopard) then prices rise further.
You might be able to get away with just you and a porter-guide, carrying most of your gear yourself and doing it like a trek on your own in the West (which would be more flexible) but local expectation often tends toward something more elaborate (guide, cook, multiple porters, etc).
