However, depending on the context, you can use other greetings like:
* Buenos días: Good morning
* Buenas tardes: Good afternoon
* Buenas noches: Good evening
* ¿Qué tal? How are you? (formal)
* ¿Cómo estás? How are you? (informal)
It's always a good idea to use a friendly greeting and a smile! Colombians are generally very warm and welcoming people.
