Travel Destinations of Antigua Guatemala (Guatemala).
Guatemala is a poor country with many things to see and do. There are famous Maya-ruins near Tikal in the tropical forest. There is volcanic, picturesque Lake Atitlan with nearby Panajachel and Chichicastenango, where many locals sell their stuff on very colorful markets. Last but not least you can get 1:1 Spanish classes in the very beautiful and former capital, Antigua Guatemala.

Old Guatemala is a nice, colonial city amidst several active and inactive volcanos. Several tourists settled here and opened little shops and restaurants. Highly recommended.
If you like to learn Spanish, this is certainly one of the better options with a wide variety of schools. 4-6 hours per day for a month with overnight stay at a local family and you are ready to discover Latin America.
