A Sirdar is a Sherpa mountain guide 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:

  • assigning responsibilities to the other guides.
  • hiring and paying local porters
  • purchasing local food during the trek/expedition
  • making the final decision regarding route choices
  • 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.

Also a Sirdar was a rank equivilent to Comander in Chief, in the 19th Century Egyptian Army.
