The Underworld is located under DOA (Dead On Arrival) Recording Studios in Los Angeles, California. It's where the souls of dead people go when they die. The Underworld is divided into various sections.
DOA Recording Studios

The entrance is managed by Charon, the reaper of souls. He takes them into an elevator and heads down, where they sail across the River Styx toward the opposite shore. On that shore, Cerberus, a three-headed dog born from Echidna and Typhon stands guard. The souls must pass by Cerberus toward their afterlife. Once they pass Cerberus, they cannot leave.
Door of Orpheus
( http://camphalfblood.wikia.com/wiki/Door_of_Orpheus )
The Door of Orpheus is a lesser-known entrance, which stands in Central Park, New York. Orpheus created it to retrieve the dead spirit of his wife, Eurydice. Music is required to open this door and Percy Jackson and Nico di Angelo used it in The Last Olympian with Grover Underwood's reed pipes. It lets out behind the main gates, therefore being more direct to Hades' palace.
*The Doors of Death
( http://camphalfblood.wikia.com/wiki/Doors_of_Death )
The Doors of Death act as way for Thanatos to quickly enter and exit the Underworld. However, he claims that the doors aren't in a physical place and normally only he knows where they are.
**Other Entrances/Exits to the Underworld
( http://camphalfblood.wikia.com/wiki/Keys_of_Hades )
While the above entrances are the main ways to get into the Underworld, there are other ways to get out as shown in The Demigod Files. Hades can use the his keys to create and close gates to the Underworld almost at will. The exact locations of these entrances are unknown.
*Some of Thanatos' Children are capable of knowing where the Doors of Death are in the Mortal World which will let them appear somewhere in the Underworld
**The Children of Hades are also capable of creating their own entrance to the underworld with their Shadow Traveling ability though they'll need training.
(You must post here before going further and please mention HOW you entered. This thread also acts as the exit. After posting here you have to go through the River Styx if you entered and gained Charon's services the 'tranditional' way.)
