As a noun, entrance means an act of entering or something that provides a way to enter something. You can make a grand entrance when you arrive at a party, as long as you can actually find the entrance.
Entrance has two pronunciations. If you put the accent on the first syllable, the word is a noun meaning the act of entering or the way into something ("an entrance to the building"). If the accent is on the second syllable, then entrance is a verb meaning "to enchant, charm, or enamor" — "You will be entranced by the movie; the scenery looks so real you will swear it is growing in the theater."
