A Sardar or Sirdar is a Sherpamountainguide who manages all the other Sherpas in a climbing expedition or trekking group. The Sirdar is typically the most experienced guide and can usually speak English fluently. The Sirdar's responsibilities include:
handling other trip logistics such as dealing with government officials or police.
The normal progression to Sirdar usually involves starting as a porter, working their way up to being a kitchen assistant, on to an assistant guide and then finally to Sirdar. Sirdars do not normally carry loads but will do so on occasion such as carrying the pack of a client who is having difficulties from altitude sickness.
