Tipping
Standard for all tourist services
Tipping is standard in the Peruvian tourism industry, but not for other industries. All guides, whether for treks or for an hour in a museum, should be tipped. The kind of restaurants that cater to tourists and accept credit cards expect a 10% tip. Local restaurants that cater to Peruvians and accept only cash do not expect tips, but if you have excellent service, you should leave s/2 to s/5 PEN as a tip.
Tipping guides
Tips for guides are much more complicated. A museum guide that you spend an hour with should receive s/5 to s/10, depending on their services. A guide treks with you for four or five days and gives you tours of archeological sites should be tipped $10 to $20 USD per day.
