Rockstar Games has always been obsessed with burying secrets in places you’d never think to look. One of the biggest ones—and arguably the creepiest—is the old, boarded-up mineshaft tucked away in the mountains. For years, people just drove past it on the way to a heist or a race, thinking it was just part of the scenery. It isn’t.
Actually, if you're playing the original PS3 or Xbox 360 versions, it is just scenery. But for everyone on PC, PS4, PS5, and the newer Xbox consoles, that door isn't just a texture. It’s an entrance to a dark, damp grave.
Finding the Abandoned Mine Location
You’ll find the entrance to the abandoned mine in the Great Chaparral area, which is basically the hilly transition zone between the city and the desert. If you’re looking at your map, look for where the winding mountain roads start to get messy north of Los Santos.
The easiest way to find it is to look for the intersection of Baytree Canyon Road and Joshua Road. From there, you want to head slightly uphill into the brush. You’re looking for a small, dusty clearing with some old rusted railroad tracks that lead straight into a mountain wall.
The door is covered in wooden planks. They look solid. Most players shoot them with a pistol, see no bullet holes, and walk away. That’s the mistake. You need something with a bit more "oomph" to get inside. A simple grenade, a sticky bomb, or even just driving a fast car into it (though I wouldn't recommend that) will shatter the wood.
Once the dust settles, the darkness stays. Bring a flashlight. Seriously.
The Mystery of the Dead Body
Once you’re inside, the atmosphere shifts. It’s quiet. Too quiet. As you walk deeper into the tunnels, the light from the entrance disappears, and you’re left with whatever weapon light you’ve got.
If you explore the left-hand path of the fork, you’ll eventually stumble upon a corpse. This isn't just some random NPC. This is Isaac, a former film associate who met a nasty end back in the 1940s.
This is part of a specific side mission called the Murder Mystery, which is exclusive to Michael. To actually "solve" it, you can't just find the body. You have to find four cryptic messages carved into walls around Los Santos first. They say things like "Old Fred acts nice, but it ain't so!" and "David Richards knows."
Steps to Solve the Mystery:
- Find the four wall carvings in the city (Gentry Manor, Galileo Observatory, City Hall, and the Oriental Theater).
- Locate the sunken body off the coast of Fort Zancudo.
- Read the confession letter on Solomon Richards' desk (available after the mission "Meltdown").
- Enter the mine and find Isaac.
Doing this unlocks a set of Vintage Noir filters for your game. It turns the whole world into a grainy, black-and-white 1940s movie. It’s a vibe.
GTA Online vs. Story Mode
Here is where it gets kinda confusing for people. The mine exists in GTA Online, but it’s a bit different.
In Story Mode, Isaac’s body is always there once you’ve triggered the right flags. In GTA Online, the body is missing. The mine is just a big, empty, spooky tunnel. However, it isn't useless.

Rockstar actually uses this interior for certain Bunker Resupply missions. If you’re running a gunrunning business, you might get a mission where you have to head into the mine to retrieve supplies. Also, some players have found that the Antique Cavalry Dagger spawns inside one of the tunnels.
If you're just looking for a place to hide from a Bounty hunter or an Oppressor Mk II griefer, the mine is actually a top-tier spot. Most people don't know the door can be blown open, so they’ll just see your blip on the mountain and assume you're glitching.
Why This Place Still Creeps People Out
There’s a lot of "Mt. Chiliad Mystery" energy surrounding the mine. People have reported hearing strange noises, whispers, or even seeing "ghosts" in the tunnels.
Is it haunted? Probably not. Rockstar's ambient sound design is just really good at making you feel uneasy in dark spaces. The dripping water and the creaking wood are designed to make you look over your shoulder.
There are also a lot of dead ends. The mine isn't huge, but it's twisty enough that if you don't have a light, you'll find yourself running into walls. It’s one of the few places in the game that feels genuinely disconnected from the chaos of Los Santos.
Getting the Most Out of Your Visit
If you’re going to head up there, don't just run in and out.
Try shooting the barrels. Some of them contain fuel, and if you light a puddle, the fire looks incredible reflecting off the damp cave walls. It’s also a great spot for Snapmatic photos if you’re into the roleplay or photography side of the game.
Another tip: if you’re in GTA Online and the door won’t break, try using the Up-n-Atomizer. It usually knocks the planks right off without the risk of you blowing yourself up in a tight space.

To get the full experience, start the Murder Mystery as Michael. It gives the location a purpose. Without the backstory of Fred Quincy and the film studio betrayal, it’s just a hole in the ground. With it, it’s a piece of Los Santos history.
To wrap this up, grab some explosives, head to Great Chaparral, and see it for yourself. Just make sure your flashlight has batteries.
Actionable Steps:
- Check your map for the Great Chaparral region north of the Vinewood Hills.
- Look for the railroad tracks near the intersection of Baytree Canyon Road.
- Equip a grenade or sticky bomb to clear the entrance.
- If playing as Michael, ensure you've found the wall messages first to trigger the Noir reward.
- Use the interior for tactical cover in GTA Online sessions to lose a 5-star wanted level or hide from players.
