Blue Hell refers to a glitch that is present in almost all games in the Grand Theft Auto Series.
Blue Hell is the name given in the player community to the area underneath the landmass in all Grand Theft Auto games. The name first started in Grand Theft Auto III in which the area underneath the landmass is usually blue, but its color usually depends on what time of the day it is.
The player is not supposed to be able to access Blue Hell, but several game glitches (including 'holes' in the world terrain) can result in the player ending up there. When the player falls into Blue Hell, they will fall through the air for a few seconds before re-spawning on the nearest pedestrian pathway (or vehicular if the player is in a vehicle). This is a game mechanic implemented so the player doesn't end up falling indefinitely if he ever accidentally enters Blue Hell. The Blue Hell in Grand Theft Auto: San Andreas is the easiest to access and explore with the use of the in-game Jetpack.
Grand Theft Auto III
Going eastwards up the sloped alleyway in Saint Mark's, north of Marco's Bistro on Portland. The wall at the end of the backyards on the left hand side is not solid and you can easily fall through. After a few seconds in Blue Hell, the player will land in the middle of the main road just to the east of where you were.
In the Staunton IslandLCPD Station, one of the higher walls is not solid. The player can easily enter and fall into Blue Hell. After the fall, the player will land in front of the station's car park entrance.
If the player rides on the subway and enters one of the trains at the second door of the first car, and then exits the train at Francis International Airport, the player may appear above the station. Walking above the tracks (the player have to jump over one of the first electricity things in the ceiling of the tunnel, otherwise the player will fall of the roof) and off them will make the player fall into Blue Hell and reappear at Francis International Airport. This is a good method to reach the whole Shoreside Vale without cheats or mods, if you not have unlocked it (if the player die or get busted there, the player will re-spawn on the hospital/police station on the nearest island that the player have unlocked). Alternatively, the player may decide to walk across the tunnel (tested on PC and iPad version).
On Staunton Island, some sections of the Liberty Memorial Coliseum are unsolid, and if the player manages to get into a hole, the player will fall into Blue Hell and re-spawn on the nearest street.
At Joey's Garage on Portland, if the player does the "Accessible Joey's Garage-glitch", one of the walls isn't solid. If the player goes through it, the player will fall into Blue Hell and re-spawn on the street.
At Ghost Town, there's a large Blue Hell entrance where the half of the town is situated.
At the Francis International Airport tunnel entrance's left side (between a really low wall and the edge of the tunnel).
Grand Theft Auto: Vice City
If, when playing the PS2 version, your PS2 is unable to load or have problems loading, the ground might not be loadedand you will fall into Blue Hell and spawn on land a few seconds later. Alternatively, the ground may become untextured and the game will freeze.
If you use the Rhino's turret combined with the flying cars cheat and you somehow reach the top of buildings past the game's height limit, you may see a large hole instead of a roof. This acts as an entrance to Blue Hell.
During the mission Bombs Away!, when the "Seaways" code is activated and the RC Plane gets under the pier, it will enter the Blue Hell.
A Blue Hell is also located besides Cafe Robina, it can only be accessed by using an Angel.
If the player performs a specific stunt in Downtown and falls into Howlin' Petes Biker Emporium, he will access the Blue Hell.

In the android version, if the players walks near the slopes in the parking lot of VCPD at Washington Beach, he will fall into the Blue Hell.
In Esplanade North, San Fierro, the player will see several docks jutting out into the San Fierro Bay with warehouses situated upon them. Next to one of these docks is a submarine called the USS Numnutz. If the player swims directly down from the submarine to the bottom of the waterway next to the dock, they will notice a greyish color which does not match the color or texture of the surrounding rock. This area is actually a hole that the player can swim through to enter Blue Hell.
If the player stands on top of a San Fierro tram and takes a picture with the camera while on the tram, CJ may fall into Blue Hell and after a few seconds, and eventually land on the sidewalk.
Also in San Fierro, there is a large clothing store in Doherty, opposite the tract of wasteland. The top portion of the wall (between the top floor and roof) is not solid, and can be accessed with a jetpack.
In Mulholland, Los Santos, there is a newspaper shop with a non-solid areas under the roof's overhang which will lead to the interior of the building, and from there to Blue Hell itself.
Get a jetpack, then go to the Mulholland Safehouse. The inside corner of the house is not solid. Walking through it will make you fall underneath Los Santos. You can use the Jetpack to explore the city via the "underground". Otherwise, if you walk through the unsolid wall without a Jetpack, you'll fall for a while and re-spawn in the street.
At Las Venturas Airport, one of the walls of the main building has a glitch wherein running at it enough will pop the player through into Blue Hell. The wall is located where the fence around the runway meets the building.
Also in Las Venturas, there is an unmarked Pay 'n' Spray east of the casino in the Come-A-Lot district. The southwest corner of the Pay 'n' Spray is not solid; if the player enters that spot via Jetpack and lets Carl Johnson sink into the hole for awhile, he will fall into Blue Hell, later automatically spawning on the sidewalk outside the Pay 'n' Spray.
Outside the Ammu-Nation in Red County, enter the Jetpack cheat (or use your own) and walk in front of the entrance. The yellow marker will disappear. When this happens, lift up and you will fly into Blue Hell.
Before End of the Line, you can blow up the big wall with explosives and inside will be Blue Hell.
If you go far out enough into the ocean and swim to the bottom of it (you must have full health/lung capacity so you live long enough) the ocean floor is not solid, and you will re-spawn somewhere in San Andreas. If you die in the process, you will spawn dead somewhere in San Andreas on the sidewalk.
There is a building in Juniper Hill, San Fierro, in which one spot on a wall is not solid, but can only be accessed with a Jetpack. It leads to the interior of the building, and then to Blue Hell. The building is between a clothing store and a safe house.
Also in Dillimore, Red County, there is a Discount Furniture store. It's name is not shown on the shop, but it is a building with a lot of signs and stickers on the windows. It's not an enterable building, so there will be no yellow marker at the entrance, but go to the entrance with a Jetpack, and fly up, and the roof will not be solid.
If you spawn a vehicle with the driver's door in a wall (so that the vehicle is partially immersed in it), get in it, and then exit it, CJ may exit on the driver's side. Since the door was inside the wall, CJ will now be inside of it as well and will fall to Blue Hell before re-spawning on the nearest street.
In Tierra Robada, below the Robada Intersection and between the Garver Bridge and the Kincaid Bridge, there is a section of unsolid terrain along the small cliff side above the sea. Obtain a Jetpack and fly downwards against the section for a while, and pretty soon, CJ will be popped into Blue Hell.
There is a tall rock somewhere in the roads of Flint County. You will need a fast vehicle to enter blue hell via the rock. Make sure you drive very fast, or it will not work. If it works, you will fall down into Blue Hell and re-spawn in Back o Beyond. If you try this again, you will re-spawn somewhere in Flint County near Los Santos.
In Temple, Los Santos, in front of a tall building, climb your vehicle to the stairs, turn left and drive to a right-most part of the wall. This can be only access by small vehicles.
Sometimes the game will poorly render and you will be able to see Blue Hell under the solidity.
Grand Theft Auto: Liberty City Stories
Near the hospital in Staunton Island is a small construction site where the player can find a ramp and jump to a platform. The player can go inside the glass of the windows in a corner and will fall into a tunnel (the same tunnel seen during the mission "Bringing the House Down"). During the mission "Bringing the House Down", the Blue Hell under Fort Staunton is solid so the player won't fall through (Tested with the use of Cheat Device). See Carson General Hospital for a full description.
(Note: You need to activate the 'Perfect Traction' cheat to perform this glitch). In front of Sweeney General Hospital at Portland View there is a place where there is an Angel and an Esperanto. Get a car, jump using 'Down', drive it to the taller roof, get out of the car or drive it and jump to the white lanes. You will fall into the Blue Hell and will re-spawn at the nearest point at Portland View or Chinatown.
(Note: Activate the 'Cars in Water' and 'Perfect Traction' cheats to perform this glitch). Go to the Shoreside Lift Bridge. Drive straight while the bridge is still lifted up. Go to the Shoreside Vale end. Jump and drive under the bridge (before a pillar) and when you have jumped in the bridge, go to the grass. You will fall into the Blue Hell and re-spawn later at the Francis International Airport end of the Porter Tunnel.
At the side of the Prawn Island bridge going to Vice City Mainland. Run onto the wall until you fall in Blue Hell, and you will respawn at Diaz's mansion.
The player can also enter Blue Hell by running towards a corner and getting hit by a tank. This with cause the player to fall into Blue Hell and spawn at the nearest land 10 to 15 seconds later.
Use a vehicle and go to an invisible wall near the freighter in Viceport. Drive and bail out and swim at the invisible wall until you have entered the wall. Swim until you see a hole, then enter the hole. You will fall into Blue Hell and reappear on the nearest piece of land.
Fly a Skimmer to the Prawn Island bridge (either InterGlobal Films or one of the mansions). Exit the Skimmer and walk until you are swimming. In the InterGlobal Films loop, swim all the way. If you use the mansion, this is dangerous. It will be split into phases. Try to swim carefully as you can suddenly reappear into the surface. You will gone down and swim more. The end of the route is at the road lanes between the three mansions and InterGlobal Films road. You will fall and spawn later. If you fall on the box, you will spawn in the Mendez Mansion. Note:The place is at Downtown-Prawn Island bridge.
Grand Theft Auto IV
Sometimes, when the player utilizes the Swingset Glitch with the Tudor swingset and a large truck like a Benson or Yankee, they may be thrown into Blue Hell for a few seconds and then back on the surface somewhere near the swing.
A trick some users do in multiplayer (in deathmatches and Free Mode) is fly a helicopter into the ground near the airport, and fly in Blue Hell, then come up in a hangar near where Annihilators spawn. Player can now shoot through the wall and kill other people, but they can't shoot the player. This is not advised, as it is cheating if it is in a death match.
Part of the south side of the Rotterdam Tower (just beneath the first high ledge) is non-solid, and can be entered with a helicopter to access Blue Hell. From here, the player can enter interiors they could not enter before, go underwater, and explore some buildings. The player may accidentally re-enter the "real world", however, as some "real" interiors are not visible from Blue Hell (this is especially true of tunnels), and entering these will restore the player to the normal game world. A video showing how to do this can be seen here
Upon entering the Schottler Medical Centre, turn right, and then right again. Player will be in a long hallway, with some windows and hospital privacy screen directly in front of the player. If the one throws a grenade near the wall, explosion will shatter the windows and move the screens. Player can now jump through the window and walk around in Blue Hell with some of the hospital's decals, doors, even pedestrians invisible for a while. However, if the one ventures too far towards the street, the surroundings will reappear. A video of this can be found here.
Driving east into the Booth Tunnel at high speed may put the player into Blue Hell for a few seconds.

At Pier 45, facing the back from the water, the one needs to swim to the left, where are a bunch of wooden posts. Then the one needs to climb on to one. Niko will jump over it as if it was a fence and land in "water". If the one swims around, they will fall into Blue Hell.
Sometimes if the player is in a destroyed helicopter (i.e no rotors/tail) and then uses the health and weapons cheat to repair the helicopter, the player will fall into Blue Hell, and can explore it with the helicopter. The player can return to the game world by flying up through the ground.
Near the West River helipad, there is a cement wall partially covered in rocks. If the one swims against this in the correct spot (The rocks should be just below the waterline) for a few seconds, they will fall onto the seafloor. Now the one can walk through the cement wall into Blue Hell, although it is very easy to fall into the nearby Booth Tunnel and return to the real world.
Near Crockett Avenue and the big roller-coaster, there is a Go-Kart racing track. If the player crashes a helicopter with the nose to the ground on the south part of the track, they should sink into Blue Hell. If the player exits the helicopter, they will spawn on whichever street is nearest, or in the water.
At the second building by the Leapers Bridge between Albany Ave and Hematite St., the one needs to go to the front entrance of the building and then jump into the handrail where the mattress is. They will fall into Blue Hell for 5 seconds and end right back out into Hematite st.
In Middle Park West in Jade St., there's an alleyway, which if the one gets stuck in its entrance (at least with the FIB Buffalo), with a side up and the other on the floor, they need to get out, and if the one then tries to get in again they will fall into Blue Hell.
Sometimes, if player spawns a vehicle in the subway, it will seem to not be there, but if they press F/Y/Triangle, there is a high chance the car will be right under the subway line, causing the player to fall in the car into Blue Hell (tested in PC version).
In the dockyard near Francis International Airport, there is an entrance north of the big oil tanks in between the pipe lines and the ground (Only works in helicopter).
Player needs to go all the way south of the Star Junction. They will see a small place with few trees and benches. When the building is on the right, the one will see a space. If the player walks into the space they will fall in Blue Hell landing somewhere on the road.
There is a large fountain-statue, located near the hospital in Easton. Player needs to take an Annihilator (It is the easiest to do so), make a little distance to the statue, and ram its nose (the Annihilator) into the left side of the statue. They may have to redo it sometimes, and they may also have to use cheats. Tested on PlayStation 3.
When driving a car on the airport runway, sometimes when directly hit by the landing gear of a moving plane a player can be pushed through the ground into Blue Hell. After falling for several seconds the player will re-spawn on the runway surface. (PS3 tested)
The Lost and Damned
In the mission Buyer's Market, whilst getting to the ground floor, if the player aims an explosive correctly, he can launch himself out of the building into Blue Hell.
The Ballad of Gay Tony
In the mission Boulevard Baby, after the shootout in the Bahama Mamas club, Luis can fall through Blue Hell when walking up the stairs after the shootout, then re-spawn outside of the club.
Grand Theft Auto V

In the construction site where a new skyscraper is being built where a gang attack is located, the player can climb a red crane that goes to a top section, where red things are, the player can walk to the corner where there is a girder not attached to the concrete. The player can fall onto the next floor, where other players cannot kill them. If the player wonders around to a certain area, the player will step down to the under floor and rarely fall into blue hell.
Spawning into Blue Hell is also common in GTA Online. If a player is located near the coast line when entering a job, he/she might spawn into Blue Hell upon immediately exiting the job to return to their last location. Upon doing so, he/she might find themselves swimming in portions of the ocean that extend below the playable world.
If a player in a tank drives up to another player's garage door and holds it closed, or waits for the vehicle to spawn and the tank drives over the vehicle driving out, the player's personal vehicle will explode and the player may be ejected into blue hell.
Via File Hacking/Modding
In the handling.cfg file, if the "float percentage (%)" value of a vehicle is set to any negative number, it will automatically go to the Blue Hell when it is driven into the water.
Removal of map objects and/or collision data allows the player to create "holes" that can be used as entrances to Blue Hell, although doing this is not recommended.
Use of the car spawn mod can lead to entrances into blue hell. Since the user can opt to have Niko "warped" into a car upon being spawned, this allows the player to stand to the left of an non-enter able building and spawn a car, which will result in the car being spawned inside the building and blue hell, with the player inside. This mod requires downloading a "script hook," which will disable any online capabilities of your game.
