i went to the caribbean last year.
preterit tense for a completed action
imperfect tense for a description

Yo fui al Caribe el año pasado. The verb is in the preterit tense for a completed action.

Explanation:

Yo fui al Caribe el año pasado. The verb is in the preterit tense for a completed action. This means that I came back from the Caribbean, it was a trip that had a beginning and an ending. The imperfect tense could be used to talk about the trip more vaguely. If, for example, you say in English "I was in the Caribbean last year", it's implied that you came back but the sentence is more imprecise. In Spanish this could be translated using the imperfect: Estuve en el Caribe el año pasado.
