Rockstar has been stuffing GTA games with secrets since the series started, but GTA V took it further than any entry before it. Some of these are things you’ll stumble into during a normal playthrough. Others took the community years of coordinate-mapping and datamining to actually crack.
Short answer: the Mount Chiliad mystery is the single biggest and most-discussed secret in the game, a cryptic mural connected to years of UFO theories. Beyond that, the most reliably documented finds are the game’s UFO sightings, the Mount Gordo ghost, and Bigfoot, all genuinely real, not urban legend.
The Mount Chiliad Mystery
A cryptic mural on Mount Chiliad has fueled UFO theories and fan debate since GTA V launched, and it remains one of the longest-running unsolved mysteries in the game.
The mural itself shows a series of symbols that fans have spent years trying to decode, tied to the game’s broader UFO and alien content. Nobody has definitively cracked what it “means,” which is exactly why it’s stayed the community’s biggest ongoing obsession.
UFO Sightings
GTA V has multiple genuine UFO-related secrets, including sightings that require 100% game completion plus specific in-game weather and time conditions.
Several UFO sightings exist across the map, including an underwater UFO wreck. The most reliable versions require you to have completed the game 100% first, then wait for rain at 3 AM in-game time at specific locations. This isn’t a rumor, it’s one of the more consistently documented secrets across the GTA community.
The Mount Gordo Ghost
Visit the top of Mount Gordo between 11 PM and midnight in-game time, and you may encounter the ghostly apparition of Jolene Cranley-Evans.
This is a genuine scripted encounter, not a glitch, tied to a dark backstory involving her murder. Timing matters here, outside that specific hour-long window, you won’t see anything.
Bigfoot
Bigfoot sightings, a running joke across the GTA series since San Andreas, actually became real, findable content in GTA V.
Players spent years searching for Bigfoot in earlier GTA games with nothing to show for it. GTA V finally delivered on the joke with genuine, documented sightings in the game’s forested areas.
Frozen Alien in North Yankton
During the game’s Prologue mission, a frozen alien body is visible under a bridge in North Yankton, and it’s still there years later during “Bury the Hatchet.”
While escaping the bank heist in the Prologue, detour toward the frozen river and drive under the bridge, an alien body is clearly visible frozen in the ice. You only get a few seconds before the mission’s chase route forces you to move on. Remarkably, it’s still there when the story returns to North Yankton nearly a decade later.
The LOST Hatch
A hidden hatch exists in the game world as a direct reference to the TV show Lost, complete with the same numeric sequence fans of the show will recognize immediately.
The Epsilon Program
A satirical cult questline lets you join the Epsilon Program, GTA’s long-running parody of Scientology-style religious movements, first introduced back in GTA San Andreas.
Playing along involves wearing robes, donating in-game money, and performing deliberately absurd rituals, all part of Rockstar’s ongoing satire rather than a random side quest.

Who this isn’t for
If you’re looking for confirmed GTA6 easter eggs, this isn’t that article, GTA6 hasn’t released yet, and any site claiming “confirmed” secrets before launch is working from trailer speculation, not verified in-game content. This guide covers GTA V specifically, a game that’s actually out and fully explorable.
Bottom line
Start with the Mount Chiliad mural if you want the game’s biggest ongoing mystery, then work through the UFO sightings and Mount Gordo ghost if you’re after content that’s genuinely confirmed and repeatable, not just fan theory.
