Outpost 51 Alien Museum in Boulder City Has Permanently Closed

(09/16/2026 UPDATE – PERMANENTLY CLOSED)

Everyday.Vegas confirmed on September 16, 2026, that Outpost 51 Alien Museum in Boulder City had permanently closed.

The alien and UFO-themed attraction operated at 1300 Boulder City Parkway next to Tom Devlin’s Monster Museum. The former Outpost 51 space is being taken over by Plan 10 Pictures, an independent genre-film studio planning classes, studio tours, and production space.

The following article has been preserved as a historical record of our October 2025 visit. Admission prices, hours, exhibits, ticket packages, merchandise, and other operational information below reflect Outpost 51 during its time in business and no longer apply.

On our long adventure of discovering cool spots and hidden gems, we came across a destination that definitely was not for everyone—but for fans of space, aliens, UFO stories, and conspiracy theories, Outpost 51 Alien Museum offered one of Boulder City’s more unusual experiences.

Located right next door to Tom Devlin’s Monster Museum, Outpost 51 served as its extraterrestrial counterpart.

Where the Monster Museum explored horror and practical effects, Outpost 51 ventured into UFO encounters, Area 51 legends, alien crash stories, science fiction, and government conspiracy lore.

Inside, visitors encountered life-size alien figures, crash-site recreations, movie-inspired characters, and exhibits that blurred the line between pop culture, folklore, and decades of UFO speculation.

A Walk Through Another World

Entering Outpost 51 immediately set the tone.

One of the first major displays recreated a scene inspired by War of the Worlds, introducing visitors to the museum through familiar science-fiction imagery before moving deeper into UFO history and alien lore.

The lighting, sound effects, props, and staged environments helped turn what could have been a collection of static displays into a more immersive walkthrough.

From there, the experience shifted between ancient-alien theories, alleged UFO crash sites, government experimentation stories, and recognizable characters from science fiction.

Visitors encountered petroglyph displays and recreations connected with the Roswell and Kingman UFO stories, along with scenes designed to suggest archaeological discoveries involving extraterrestrial life.

The exhibits did not present themselves like a traditional history museum.

Instead, Outpost 51 leaned heavily into the fun of the subject, mixing reported claims, popular UFO stories, conspiracy theories, cinematic references, and imaginative recreations.

One of the more playful installations was the Tall and Short Gray Mirrors, which distorted visitors’ reflections into exaggerated alien-like forms.

It gave families and groups an interactive break between the darker crash-site and laboratory scenes.

Exploring Area 51 and Beyond

A major part of the museum centered around the mythology surrounding Area 51.

One section focused on Bob Lazar, whose claims about working with extraterrestrial technology near Area 51 became one of the most widely discussed UFO stories of the late 20th century.

The display referenced Element 115, which became closely associated with Lazar’s story about alleged advanced propulsion technology.

Elsewhere in the museum, television screens played segments connected with Ancient Aliens, expanding the experience into theories about extraterrestrial contact throughout human history.

The museum continually moved between recognizable UFO lore and theatrical entertainment.

Alien Experiments, Autopsies and Desert Mysteries

Some of the most memorable sections were also the strangest.

One display featured Buster – The Desert Chimp, adding another odd chapter to the attraction’s collection of desert mysteries.

Another area recreated the infamous alien autopsy imagery that became part of UFO pop culture.

Other scenes depicted aliens connected to laboratory equipment and monitoring devices, continuing the attraction’s theme of secret government experimentation.

Each display added another layer to Outpost 51’s strange little universe.

It did not matter much whether visitors believed any of the stories. The experience worked because it embraced the mystery.

Souvenirs From Another Galaxy

Before leaving, visitors passed through a gift shop filled with appropriately strange souvenirs.

The selection included alien-themed T-shirts, playing cards, UFO merchandise, novelty items, and glow-in-the-dark souvenirs.

Even the gift-shop displays continued the theme, with vintage-looking communication and radiation equipment mixed into the merchandise.

It felt less like walking out of the attraction and more like one final extension of the experience.

A Boulder City Stop That Was Definitely Different

After finishing our visit, we walked out smiling—and hungry.

A couple of blocks away, we stopped for barbecue, turning the afternoon into a fun Boulder City combo: extraterrestrial mysteries followed by something considerably more grounded.

For its relatively compact size, Outpost 51 packed in a surprising amount of visual material.

There were props, recreations, movie references, alleged crash stories, alien figures, and enough Area 51 mythology to keep believers and skeptics debating afterward.

What Admission Included During Our Visit

At the time of our visit, admission was listed at $20 for adults, $10 for children ages 6–11, and free for children under 5.

A combination ticket with Tom Devlin’s Monster Museum was also offered for $30.

Those prices and ticket options are historical and are no longer valid because Outpost 51 has closed.

Remembering Outpost 51 Alien Museum

Outpost 51 did not take itself too seriously, and that was a large part of what made it enjoyable.

It brought together UFO folklore, Area 51 conspiracy stories, science-fiction movies, alleged alien encounters, elaborate props, and interactive displays in a small Boulder City attraction built for people willing to have some fun with the unknown.

Whether someone arrived as a believer, a skeptic, or simply a sci-fi fan, there was plenty to photograph, discuss, and occasionally question.

The museum also made an interesting companion to Tom Devlin’s Monster Museum next door, pairing horror-movie craftsmanship with extraterrestrial mythology.

Although Outpost 51 Alien Museum has permanently closed, its former space is entering another entertainment chapter as Plan 10 Pictures moves into the property.

Outpost 51 itself now belongs to Boulder City’s growing list of unusual attractions that came, created something memorable, and eventually disappeared.

This article remains as a record of our visit and the aliens, UFO crash scenes, Area 51 stories, strange experiments, and sci-fi atmosphere that once filled the museum.

The truth may still be out there—but Outpost 51’s doors are now closed.
