Tips are not mandatory. However, if you wish to tip to show your gratitude, it will be welcomed. Tipping can be in USD or Nepalese Rupees (NRS). Upon arrival in Kathmandu, it is good to carry small denominations of USD for small tips to driver, hotel staff, etc. However, hotels/restaurants in Kathmandu, already charge you with 10 % service charge. Tipping is an accepted part of trekking although it is completely a personal matter. The amount depends on your budget and appreciation of their work. Budgeting up to 10 % of the trek cost as tipping could be a guideline.
