1. The Queen Mary (Long Beach)
Historical Background
The RMS Queen Mary was constructed in Scotland and launched in 1934 as a luxurious ocean liner, known for its art deco interiors and speed records on the Atlantic. During World War II, the ship was converted into a troop transport, ferrying thousands of soldiers. After decades of service, she was retired and permanently moored in Long Beach in 1967, transformed into a floating hotel, museum, and event venue.
Paranormal Reports
The Queen Mary has earned a reputation as one of the most haunted ships in the world. Guests and staff report sightings of ghostly apparitions, including a young girl who allegedly drowned in the pool during its operational days. The engine room is infamous for unexplained mechanical noises and phantom footsteps. Many have encountered shadow figures and experienced sudden cold spots in hallways and stairwells. The first-class swimming pool area is a hotspot, with reports of dripping water sounds and the faint smell of cigarette smoke, even though smoking is banned.
Why Visit / Investigation Tips
The Queen Mary offers specialized ghost tours, including overnight paranormal investigations where visitors have a chance to explore restricted areas with experienced guides. EMF detectors, night vision cameras, and digital voice recorders are highly recommended. Some visitors suggest paying close attention to the pool deck and the engine room for the most activity.

2. Alcatraz Island (San Francisco)
Historical Background
Located in the middle of San Francisco Bay, Alcatraz Island has a layered history, first as a military fort, then a military prison, and most famously, a federal penitentiary from 1934 until its closure in 1963. Housing notorious criminals like Al Capone and “Machine Gun” Kelly, Alcatraz was known for its strict security and isolation.
Paranormal Reports
Visitors and staff frequently report hearing footsteps echoing through empty corridors, distant voices, and doors slamming shut without explanation. Many recount sightings of shadowy figures resembling prisoners or guards, particularly near Cell Block D and the solitary confinement area. At night, eerie lights and sudden drops in temperature have been noted. Some investigators claim to have captured EVPs (electronic voice phenomena) of whispered conversations and cries.
Why Visit / Investigation Tips
The island offers both day and night tours, with night tours being especially popular among paranormal enthusiasts due to the heightened atmosphere. Bringing recording equipment, night vision cameras, and EMF detectors can improve chances of documenting paranormal activity.

3. Winchester Mystery House (San Jose)
Historical Background
The Winchester Mystery House is a sprawling Victorian mansion constructed continuously over 38 years, from 1884 to 1922, by Sarah Winchester, widow of the Winchester rifle heir. Legend suggests she believed she was haunted by spirits of those killed by Winchester rifles and that building the mansion nonstop would appease them. The house is famous for its labyrinthine design, including staircases to nowhere, doors that open into walls, and secret passages.
Paranormal Reports
Numerous visitors report paranormal encounters such as apparitions of a woman thought to be Sarah Winchester herself, unexplained footsteps on empty staircases, and mysterious knocking sounds. Sudden cold spots and flickering lights occur throughout the mansion. The house’s maze-like layout seems to disorient visitors, possibly contributing to ghostly phenomena. Some report the scent of roses or lilacs, believed to be associated with the spirit of Sarah.
Why Visit / Investigation Tips
The house offers both daytime and evening tours, with the latter focusing on the paranormal. Bringing audio recorders and EMF meters is recommended, especially near the upper floors and in the “spite staircases.” Be prepared for narrow corridors and steep stairs.

6. Point Sur Lighthouse (Big Sur)
Historical Background
Constructed in 1889, the Point Sur Lighthouse was established to prevent shipwrecks along California’s rocky Big Sur coast, one of the most treacherous stretches of shoreline in the state. Isolated on a volcanic rock formation, lighthouse keepers and their families lived in almost complete isolation for decades, enduring fog, storms, and tragedy.
Paranormal Reports
The Point Sur Lighthouse is known for spectral sightings of former lighthouse keepers and their families. Apparitions are often seen in period clothing wandering the tower or gazing out toward the sea. Visitors report hearing the sound of boots on wooden floors, doors slamming without wind, and whispers during quiet moments. The lightkeeper’s house is especially active, with some reporting children’s laughter and disembodied voices calling out names.
Why Visit / Investigation Tips

Paranormal Reports
Apparitions of the Whaley family, particularly young Violet Whaley (who tragically died by suicide), are often reported.

Her death was ruled a suicide, but theories of murder still circulate.
Paranormal Reports
Room 3327 (previously 302) is believed to be where Kate Morgan stayed, and guests in that room report flickering lights, TVs turning on and off, and sudden cold drafts.

9. Preston Castle (Ione)
Historical Background
Opened in 1894 as the Preston School of Industry, this Romanesque Revival structure was a reform school for boys — many of whom were sent there for petty crimes. It was operational until 1960, and stories of harsh punishments, abuse, and even deaths make it one of the most chilling places in California.
Paranormal Reports
Visitors and investigators have reported apparitions of young boys, former staff, and one particularly infamous spirit — Anna Corbin, the housekeeper who was murdered on-site in the 1950s. Cold spots, shadow figures, slamming doors, and screams echoing down the hallways have all been documented. Some report being touched or pushed, particularly in the basement and infirmary.
Why Visit / Investigation Tips
The castle offers both day tours and overnight paranormal investigations. The infirmary and basement are key hotspots. Use EVP equipment, motion detectors, and REM pods. Bring warm clothing and flashlights, as the structure is mostly unrestored.

10. Black Star Canyon (Orange County)
Historical Background
Black Star Canyon, nestled in the Santa Ana Mountains, is a rugged and isolated region known for its violent and controversial history. In the 1830s, a massacre of Native Americans occurred here during a disputed raid. Later, legends of occult activity, missing persons, and mysterious lights fueled the canyon’s eerie reputation.
Paranormal Reports
Many visitors report hearing chanting, drums, and cries coming from the woods — especially at night. Apparitions of Native American spirits, shadowy figures, and “men in black” type entities are common in witness accounts. Reports of sudden nausea, time lapses, and the sensation of being watched are frequent. Unexplained lights float through the trees, and hikers have reported being chased by something unseen.
Why Visit / Investigation Tips
Extreme caution is advised — the trail is rugged and remote. Visit in groups, bring high-powered flashlights, thermal cameras, and a map. Avoid trespassing on private land nearby. The clearing near the old mine and the “altar rock” area are common for sightings.

11. The Cecil Hotel (Los Angeles)
Historical Background
Opened in 1927 in Downtown L.A., the Cecil Hotel was originally a glamorous destination during the city’s boom years. However, the Great Depression changed its fate, and over the decades, it became associated with poverty, crime, and death. The hotel has been linked to at least 16 documented deaths — including suicides, murders, and accidents. It’s most notoriously associated with serial killer Richard Ramirez (The Night Stalker), who stayed there during his killing spree, and the mysterious death of Elisa Lam in 2013.
Paranormal Reports
Guests and urban explorers have reported everything from dark figures in hallways to bloodstained apparitions and whispers echoing through empty rooms. Elevators have been reported to operate on their own, and cold spots appear suddenly in sealed areas. Many visitors describe feelings of dread or being watched, especially near the upper floors where several suicides occurred. Elisa Lam’s case — with her last moments captured in bizarre elevator footage — has intensified the building’s haunted status.
Why Visit / Investigation Tips
The Cecil is now partially rebranded as “Stay on Main,” and is not open for ghost tours, but the exterior draws curious visitors. Paranormal investigators recommend focusing on the alleyways, lower lobby area (if accessible), and nearby rooftop (with permission). Document with video and EVP; even casual street-side recordings have captured odd sounds.
Access / Tour Info
Currently closed for major renovations and preservation. No interior access. Exterior visits only.
12. La Purísima Mission (Lompoc)
Historical Background
Established in 1787, La Purísima is one of California’s 21 original Spanish missions. It served as a religious and agricultural center for the Chumash people under Spanish control.

Today, it is a fully restored historic site and state park.
Paranormal Reports
Apparitions of monks, Spanish soldiers, and native people have been reported. Phantom chants, organ music, and the smell of incense are often experienced in the chapel and bell tower. Tourists and park rangers have described cold spots and a sensation of unseen people walking beside them. The “Convento” — the priests’ quarters — is a particularly active hotspot where shadow figures have been captured on camera.
Why Visit / Investigation Tips
Even during the day, visitors report activity. Evening candlelight tours or special ghost events (held seasonally) offer more focused paranormal exploration. EMF meters, temperature guns, and voice recorders are highly recommended — especially in the chapel and soldiers’ quarters.
Access / Tour Info

13. Queen Anne Hotel (San Francisco)
Historical Background
Originally built in 1890 as the Mary Lake School for Girls, this Victorian-era structure was converted into the Queen Anne Hotel in the early 1900s. Mary Lake, the headmistress and original occupant, was said to be kind, refined, and dedicated to her students. After her death, stories of her spirit remaining behind began to circulate.
Paranormal Reports
The most active room is Room 410, where Mary Lake once lived. Guests frequently report their luggage being unpacked, blankets tucked in while they sleep, and the sensation of a gentle presence watching over them. Some have seen a full-bodied apparition of a woman in a Victorian gown, believed to be Mary herself. Cold spots and phantom footsteps are common throughout the hallways.
Why Visit / Investigation Tips
Book Room 410 if available, and set up EVP and static cameras overnight. Many guests report Mary’s spirit is more nurturing than frightening. Investigators suggest placing motion-triggered lights or bells to detect unseen movement.
Access / Tour Info
Open year-round as a boutique hotel. No official ghost tours, but staff are often willing to share their experiences.
14. Linda Vista Community Hospital (Los Angeles)
Historical Background
Opened in 1905 in Boyle Heights, Linda Vista was originally the Santa Fe Coast Lines Hospital, later renamed and expanded to serve East L.A. It saw a surge in patients during the Great Depression and WWII. By the 1980s, it was overcrowded, underfunded, and earned a reputation for mistreatment and neglect before closing in 1991.
Paranormal Reports
Apparitions of former patients, particularly children and elderly figures, are frequently reported. Screams, gurney wheels echoing down empty halls, and the smell of antiseptic have been described. Some investigators claim to have heard prayers or moaning from long-abandoned operating rooms. The third floor and basement are considered extremely active, with some reporting oppressive feelings and nausea.
Why Visit / Investigation Tips
While the hospital has since been converted into senior housing and access is restricted, urban explorers once considered this one of L.A.’s most active paranormal sites. If access is ever permitted again via filming or special tours, focus on surgical suites, the ER entrance, and the boiler room.
Access / Tour Info
Currently private property with no public access. No official ghost tours offered at this time.

Paranormal Reports
Visitors report hearing applause, laughter, and piano music coming from the opera house even when it’s empty. Marta herself claimed the spirits of miners and former residents attended her performances. Shadowy figures and murmuring voices have been heard in the hotel wing, with Room 24 being particularly notorious for cold spots and restless energy.

16. Greystone Mansion (Beverly Hills)
Historical Background
Built in 1928 by oil tycoon Edward L. Doheny for his son, Ned Doheny, Greystone Mansion is a sprawling Tudor-style estate nestled in the hills of Beverly Hills. Just months after moving in, Ned Doheny was found dead in a murder-suicide involving his personal secretary, Hugh Plunkett, under mysterious circumstances. Although the official story claimed Plunkett killed Doheny, many inconsistencies remain.
Paranormal Reports
Visitors and staff have reported strange sounds in the former bedroom where the deaths occurred — including faint whispers, phantom gunshots, and cold air pockets. Apparitions of a man in 1920s attire have been seen pacing the hallways. Some paranormal groups believe that the mansion holds residual hauntings — energy trapped by the trauma of the violent deaths and family scandal.
Why Visit / Investigation Tips
Though much of the interior is closed to the public, the estate grounds and occasional public events offer opportunities for investigation. The central staircase, courtyard, and exterior of the East Wing (where the deaths occurred) are the most active zones. EVP sessions near sundown yield the most results.
Access / Tour Info

17. Madonna Inn (San Luis Obispo)
Historical Background
Opened in 1958 by Alex Madonna, the Madonna Inn is a flamboyant hotel known for its 110 themed rooms, pink dining room, and over-the-top decor. Beneath the quirky surface, however, are persistent rumors of hauntings — particularly involving the land it was built on, which was once near stagecoach routes and early settler encampments.
Paranormal Reports
Certain rooms (notably the “Caveman Room” and “Room 160”) have reports of strange lights, cold breezes, and flickering electronics. Staff have witnessed glasses sliding off tables, chandeliers swaying on calm days, and disembodied laughter. Some visitors claim to have seen a woman in white walking through the Gold Rush Steakhouse late at night.
Why Visit / Investigation Tips
Guests interested in paranormal activity are encouraged to stay in the original wing. Ask hotel staff (discreetly) about their personal experiences. Audio recorders and motion-triggered cameras work well here, especially during overnight stays.
Access / Tour Info

18. Crosby Mansion (Del Mar / San Mateo County)
Historical Background
Often confused due to name variations, the Crosby Mansion in San Mateo County (not to be confused with Bing Crosby’s Del Mar estate) was built in the early 1900s by wealthy entrepreneur P.J. Lynch, later purchased by famed socialite and businessman George Crosby. The mansion was abandoned for years, and many believe tragic events unfolded during that time, including unverified stories of accidental death and suicide.
Paranormal Reports
Numerous reports describe a woman sobbing in the upstairs library and cold spots near the second-floor balcony. Phantom music and smells of pipe tobacco are common. Visitors who’ve been inside claim to have felt watched or unwelcome, especially in the parlor and master bedroom.
Why Visit / Investigation Tips
Tours are extremely rare and usually limited to historical societies or special events. If visiting during one of these, focus EVP sessions in the upper-floor study and main staircase. Respect boundaries, as much of the house is still under historical preservation.
Access / Tour Info
Limited access via pre-arranged private tours through the San Mateo County Historical Association.
19. The Herb House (Nevada City)
Historical Background
The Herb House is a small 19th-century structure located in Nevada City’s historic district. Originally used as a herbal apothecary, it was later turned into a residential home. Its connection to early settlers, and possibly the use of herbal treatments during the 1800s epidemics, gives it a grim medical history.
Paranormal Reports
Unexplained floral scents, cold spots, and flickering candlelight have all been reported — despite no candles being lit. Apparitions of a man in a vest (likely the original apothecary owner) and a woman in pioneer dress have been seen. Some claim to hear the soft rattling of glass bottles late at night.
Why Visit / Investigation Tips
Interior access is limited, but the exterior can still be explored respectfully. Paranormal groups recommend placing recorders near windows at night to pick up residual activity. Bring infrared thermometers and motion-sensitive lights.
Access / Tour Info
Privately owned. Occasionally opens for local ghost walks during October in Nevada City.
20. Rios-Caledonia Adobe (San Miguel)
Historical Background
Constructed in 1835, the Rios-Caledonia Adobe was originally part of the San Miguel mission system. It served as an inn and stagecoach stop along El Camino Real. Later used as a private residence, school, and post office, it saw periods of abandonment before being restored as a historical site.
Paranormal Reports
Visitors report shadows moving behind windows, flickering lantern lights, and soft murmurs in Spanish. Staff have reported hearing footsteps in empty hallways and doors locking or unlocking on their own. Some attribute the energy to soldiers and travelers who passed through during California’s early days.
Why Visit / Investigation Tips
The adobe’s thick walls and historic atmosphere make it ideal for EMF and EVP sessions. The back room (former jail cell) and courtyard are known activity centers. Visit during quiet hours for best results.
Access / Tour Info
Operated by the Friends of the Adobe, open for tours most weekends. Check their official website for hours and events.
