accessible places in Hogwarts or secrets

I have thought that students can access certain places such as "the chamber of secrets" "the trapdoor of fluffy" "cursed vaults" "underground caves in the castle" but that to get to these places there are a number of things that you have what to do to make it more realistic instead of just putting topics. And that when these students are in those places there are consequences for teachers or prefects for example "take points" "put a punishment punished such day"
