Hoia Baciu Forest

Just west of Cluj-Napoca, Hoia Baciu forest earned the nickname "the Bermuda Triangle of Transylvania" after biologist Alexandru Sift began cataloguing its odd features in 1968, including an open, perfectly circular clearing where locals say nothing grows well and hikers report sudden nausea or disorientation. That same year, technician Emil Barnea photographed what he described as a disc-shaped object over the clearing, an image that circulated widely and helped cement the forest's paranormal reputation alongside older shepherd folklore about a herder who vanished into the woods with two hundred sheep and was never found. Visitors regularly describe losing track of time inside the forest, unexplained anxiety, and trees bent into strange, twisted curves unlike the healthy growth just beyond the treeline. Paranormal tour groups now run regular night visits to the clearing, still widely treated by locals as a place best avoided after dark.

Hoia-Baciu is a working periurban wood of roughly 300 hectares on the western edge of Cluj-Napoca, on the slope known as Dealul Hoia. It has an open-air ethnographic museum inside it, a sports base beside it and a city bus route that stops at its treeline. The label attached to it in English — "the most haunted forest in the world" — is younger than most of the people who repeat it, and it is not what the Romanians who actually studied the place ever said. The folkloric account of the name is the one every guide tells: a shepherd called Hoia is said to have walked in with two hundred sheep and never come out, and the wood became "the forest where Hoia the shepherd was lost". Local reporting treats this as legend rather than record; the etymology is uncertain, and Baciu is also the name of the neighbouring commune, while baci is simply the Romanian word for a head shepherd. No missing-persons file, no date, no parish entry has ever been produced for him. The documented story begins in July 1953. Alexandru Sift (1936-1993), then still a student and later a biologist, was at the edge of the wood when he reported seeing a grey object shaped like a V lying on its side. That sighting turned into a lifetime's obsession. According to Vasile Surcel, writing in Jurnalul Naţional in 2004, Sift criss-crossed the area for some three decades and took more than 60,000 photographs, convinced he was recording structures invisible to the naked eye. Note what he was not doing: he was not hunting ghosts. Sift's frame was ufology and anomalous physical phenomena, and it stayed that way. Then came 18 August 1968. Emil Barnea, a 45-year-old military technician, was spending a weekend in the wood with Zamfira Matea and two friends who kept their anonymity. Around one in the afternoon, at the clearing known as the Poiana Rotundă, he photographed an object moving low and silently over the trees. What is solidly on the record is the aftermath rather than the object: on 18 September 1968 AGERPRES, the Romanian state news agency, announced the observation and photographing of a UFO in the Baciu forest about a month earlier. The images were interpreted by the engineer Florin Gheorghiţă and, according to Descoperă.ro, were presented at the international ufology congress held in Acapulco in 1977. They have been called the clearest UFO photographs ever taken in Romania — a superlative repeated by the Romanian press for half a century, though the public record contains no independent forensic examination of the negatives. From the mid-1970s the work passed to Adrian Pătruţ, professor of chemistry at Babeş-Bolyai University in Cluj and president of the Romanian Society of Parapsychology. His group added some 15,000 photographs of its own and in 1995 he published the monograph Fenomenele de la Pădurea Hoia-Baciu with the Dacia press, reproducing what survived of Sift's archive — most of which vanished after Sift's death in 1993. Pătruţ described short-lived, shape-shifting "plasmatic" structures with an almost Brownian motion, and built a unifying theory he called a global polymorphic phenomenon. His own stated conclusion, quoted by the Cluj county library's documentation of the book, was that it is extremely difficult to formulate one at all. So the entire Romanian tradition — 1953 to 1995, two researchers, 75,000 photographs, one monograph — is about lights, plasmas and unidentified objects. The ghosts arrive in English. Syfy's Destination Truth filmed in the wood for an episode broadcast on 9 September 2009; Travel Channel's Ghost Adventures built a Transylvania special around it in 2013, with Pătruţ himself on camera in the clearing; night tours became a fixture, with guide Marius Lazin running walks three nights a week for more than a decade; and in October 2025 a Guardian travel feature by Daniel Stables put the phrase in a headline — "World's most haunted forest". The reputation is real. It is roughly fifteen years old.

Hoia-Baciu is not an attraction with a gate and a ticket desk. It is public forest on the western side of Cluj-Napoca, roughly 300 hectares on Dealul Hoia, and access is free at any hour. The easiest way in on foot is through the Parcul Etnografic Naţional "Romulus Vuia", the open-air ethnographic museum that sits inside the wood; it opens Wednesday to Sunday, 09:00-16:00 in winter and 10:00-18:00 in summer, closed Monday and Tuesday, and is worth the detour in its own right. City buses 26, 27, 28, 30 and 41 serve the Piaţa 14 Iulie stop nearby, and lines 31 and M31 stop close to the forest itself. By car it is about five kilometres from the centre. The practical warning matters more here than at most sites on this atlas: the paths are not waymarked. Routes over Dealul Hoia and down into the Cheile Baciului exist, but they multiply into a tangle of unmarked tracks, and the wood is on a slope with poor sightlines. Take a paper map or an offline GPS track, wear boots — it turns to mud quickly — and do not count on phone reception or on your battery, which is the prosaic version of the electronics anomalies the Cluj tourist board itself mentions. Guided night walks are the standard way people see the Poiana Rotundă. Operators such as the Hoia-Baciu Project have run them for over a decade; guides Marius Lazin and Alex Surducan are the names that recur in Romanian coverage. A typical outing starts between 18:00 and 22:00 depending on the season, lasts about three hours, covers three and a half to four kilometres on foot, and is priced around €96 per person for a party of two, with pickup in Cluj, torches and rain ponchos included. Operators describe them as presentation walks rather than scare experiences. One last thing to expect. Logging has been eating into the wood for years: Business Magazin reported in February 2019 that a new forest road had been driven through and that the vegetation around the clearing was being damaged, quoting Surducan saying that the Poiana Rotundă is the spot every tourist asks for and that part of its wall of vegetation was already destroyed. Go in expecting a real, worked, partly cut-over periurban forest, not a set.
