You have to get all five things first. And not one of them is in Zeus's realm. So after you get all of them you go to where you first saw Athena and talk to her then go and get Hercule's and he will break the lock. (Hercules sees Medusa and turns into a statue after he opens the gate)
You get Hercules, from Herc's hut, to smash it open after you use him to get a gift from Poseidon and Hades.
you have to get Hercules to open it
to get Zeus's trident on poptropica you have to buy it for 250 credits
Well first of all Zeus is spelled wrong..and second if you are not a god you have no chance of getting in. For example if you have ever seen or read the lightning thief you would see that pierces can cross the gate because he is half god but his mom cant pass because she is full human.

you fight Zeus to become a god
