How to Say "indoors" in Spanish
The Spanish word for “indoors” is “dentro” — A1 level. This is a very common word in everyday Spanish.

Examples
Hace frío, vamos a jugar dentro.
It's cold, let's play inside.
Por favor, espere dentro.
Please, wait inside.
Miró hacia dentro, pero no vio a nadie.
He looked inside, but he didn't see anyone.
Answering 'Where?'
Use 'dentro' by itself to answer the question '¿Dónde?' (Where?). It tells you the general location of something without needing to say what it's inside of.
'dentro' vs. 'adentro'
Mistake: “Using 'dentro' and 'adentro' exactly the same way.”
Correction: 'Dentro' is a general location. 'Adentro' often suggests movement *into* a place. For example, '¡Vamos adentro!' (Let's go inside!). When in doubt, 'dentro' is usually a safe choice.
