Grand Theft Auto V (GTA V) isn’t just about completing missions or pulling off high-stakes heists—it’s also a treasure trove of hidden locations, mysteries, and Easter eggs that Rockstar Games carefully tucked into the game. From references to UFOs and Bigfoot to secret interiors and special items, these hidden gems make GTA V one of the most replayable open-world games ever created.

In this guide, we’ll explore the most fascinating hidden locations and Easter eggs in GTA V, how to find them, and why they matter.

1. Mount Chiliad Mystery (UFOs & Glyphs)

  • Location: Top of Mount Chiliad

  • On the wall inside the cable car station, you’ll find strange glyphs and murals hinting at UFOs, jetpacks, and mysteries. After completing the game 100%, if you visit the summit during a stormy night at 3 AM, you’ll see a UFO hovering above the mountain.

  • This remains one of GTA V’s most famous unsolved mysteries.

2. The Ghost of Mount Gordo

  • Location: Mount Gordo cliffside

  • Between 11 PM and 12 AM in-game time, head to the cliffs of Mount Gordo. There, you’ll see the ghost of Jolene Cranley-Evans, the murdered wife of Jock Cranley (a politician in GTA lore).

  • If you get close, the ghost disappears, leaving only the word “Jock” written in blood.

3. Bigfoot (Sasquatch)

  • Location: Various forests (especially around Mount Chiliad)

  • Players can spot a Bigfoot silhouette during the “Predator” mission. Later, in GTA V: Enhanced Edition, Rockstar added a side mission called “The Last One,” where Franklin can hunt down a man dressed as Sasquatch.

  • This Easter egg is a fun callback to GTA: San Andreas myths.

4. Alien Under the Ice

  • Location: North of Prologue mission (near Ludendorff, North Yankton)

  • During the very first mission in North Yankton, you can spot a frozen alien beneath the ice if you drive off-road by the river.

  • It’s one of Rockstar’s earliest teases about aliens in GTA V.

5. Infinity Killer Letters

  • Location: Scattered around Blaine County

  • By exploring the map, players can find serial killer letters left by Merle Abrahams, the “Infinity Killer.” These notes hint at eight missing people and include creepy rhymes about “infinity lives.”

  • A true hidden gem for lore enthusiasts.

6. UFO Sightings

  • UFOs appear in multiple places after 100% completion:

    • Mount Chiliad Summit

    • Fort Zancudo military base

    • Above Sandy Shores

  • Each has a slightly different design, with some being Epsilon Program-related, adding to GTA’s conspiracy-laden world.

7. Playboy Mansion Party (Parody)

  • Location: Vinewood Hills

  • A hidden villa exists that’s clearly a spoof of the Playboy Mansion. At night, NPCs throw lavish pool parties, complete with music and models.

  • It’s not marked on the map, making it feel like a true hidden discovery.

8. The Hatch Underwater (Lost Reference)

  • Location: Off the east coast, underwater

  • Deep under the ocean, you can find a mysterious hatch with a glowing light inside, a clear reference to the TV series Lost.

  • It has no gameplay function, but it’s one of the creepiest Easter eggs.

9. Chiliad Mystery Cave Drawings

  • Spread around Blaine County, strange cave drawings depict aliens, UFOs, and cryptic messages.

  • They tie into the larger Mount Chiliad conspiracy and hint at Rockstar’s love for fan theories.

10. Secret Interiors (Abandoned Mineshaft)

  • Location: Great Chaparral

  • An abandoned mineshaft is hidden in the mountains. With explosives, you can break open the entrance and explore inside.

  • The cave doesn’t lead anywhere major but adds an eerie sense of history to the map.

Final Thoughts

Rockstar’s GTA V is more than just missions and money—it’s an immersive sandbox full of mysteries.

From paranormal ghosts to government conspiracies and alien life, GTA V blends satire with supernatural intrigue in a way no other open-world game does.

👉 If you’re aiming for 100% completion, exploring these hidden areas is a must. Not only will you discover Rockstar’s attention to detail, but you’ll also uncover the secrets that make Los Santos one of gaming’s most legendary worlds.
