Is it easy to get a sunburn in Peru?
Peru is just south of the equator. The closer you are to the equator, the stronger the sun is. For this reason, it's fairly easy to get sunburned in Peru, especially at higher elevations.
In order to protect yourself against the sun, it's important to wear sunscreen with at least SPF 30. Sunscreen can be purchased from most stores in Peru. It's also a good idea to wear sunglasses and to stay hydrated, especially when you're on the beach. Bring a water bottle with you and take breaks in shade throughout the day.
