The local currency is needed to get by in Everest Base Camp Trek and Nepal. Therefore, the foreign currency must be exchanged for Nepalese rupees. Money exchange is easy in Nepal. There are numerous exchange centers in Kathmandu. Foreign currency can also be exchanged at the airport or bank. The easiest access is via ATM. You may not get a good exchange rate on a hike, and it may not even be accepted.
The bank in Nepal is open Sunday through Thursday from 10 am to 4 pm and Friday from 10 am to 3:30 pm. They are closed on Saturdays and public holidays. Hotels and restaurants in Kathmandu also accept credit cards but not in the EBC trek.
The ATMs have a maximum cash withdrawal limit and are subject to exchange rates and service charges. Likewise, Nepalese currency might not be accepted in any other country. Hence, it is important to change them before you leave.
Can I change money, or are there ATMs while trekking?
On the EBC trail, ATMs are only available in some locations in Namche Bazaar or Lukla. Any place is higher than that; there is no ATM. So, carrying some hand cash is always a good option.
