Antigua is the tourism capital of Guatemala. Almost all the tourists flee away from Guatemala City as soon as their airplane lands on the Aurora International Airport. Since Antigua is only 45 kilometers from Guatemala City and it is after all more charming and less expensive, many people come here. La Antigua has all the services you need to travel everywhere in Guatemala. Antigua has hotel accommodations for all the budgets. Actually, Guatemala is a very inexpensive destination and you can see many different things in about two weeks. You can be exposed to Mayan ruins, pristine beaches, lakes, rivers, waterfalls, colonial towns, Mayan, Hispanic and Garífuna peoples and cultures, tropical and cloud forests, exotic fauna and flora, exquisite Guatemalan and international cuisine, all with the budget of a backpacker. You can also do all this with a little more money and get better hotels and services. Not too bad for a tiny and complex country.
