English is a language that some Guatemalan's receive as a subject in school; however, it is by no means a primary language.  But don't worry!  Thousands of tourists visit Guatemala each year without speaking Spanish and do just fine.  It's actually a lot of fun learning and speaking a few key words and phrases such as "buenos dias!" - good morning! - and the Guatemalan people are typically extremely friendly and very anxious to engage with and assist travelers.
