The most important thing for guests to remember is that guiding is a service business, and all guides and wranglers throughout the world rely on their tips as part of their earnings. Having said that, like any service, they must earn it. What you choose to tip is up to you, but the following guidelines may give you a place to start: 10-15% of the trip cost, $15-25 a day for the cook per person who also acts as a camp valet, $15 per person for each wrangler/packer who packs gear up and back, etc. If you are coming with a group, it is always a good idea to talk with others about how much they plan to tip, so as to avoid embarrassment. Give the tips to the individuals themselves or a manager rather than a pool to be split up. We have envelopes at the base camp if you need them.
