Learn Spanish (Latin America): ¿Ha acampado el aventurero alguna vez? Ayer durmió aquí. - Has the adventurer ever camped? Yesterday he slept here.

In Latin American Spanish, the present perfect is mainly used for life experiences that don't have a specific timeframe. Adding alguna vez (ever) makes it about his general experience up to now. The second sentence switches to the preterite because ayer (yesterday) is a closed, finished time period.

Does alguna vez directly translate to 'ever'?

Yes, in questions like this, alguna vez means 'ever' (literally 'some time'). It is the standard way to ask if someone has experienced something in their life, and it pairs naturally with the present perfect.

Why is it durmió instead of 'dormió'?

The verb dormir is an -ir verb that has a stem change. In the preterite tense, these verbs have a stem change (o to u, or e to i) only in the third-person forms (he/she/you formal/they). So, the o changes to u to make durmió for 'he slept'.

Why is the subject el aventurero placed after the verb ha acampado?

In Spanish questions, it is very common to invert the word order and put the subject after the verb. With compound verbs like the present perfect (ha acampado), you can never split the two verb parts, so the subject must go after the entire verb phrase.
