Hoia-Baciu Forest

Hoia-Baciu is a mixed oak and hornbeam wood of about three square kilometres on a ridge west of Cluj-Napoca, Transylvania’s largest city, next to the open-air section of the Ethnographic Museum of Transylvania. For most locals it is simply a place to walk, cycle and run; part of it is now a bike park, and a pocket of rare downy-oak woodland is protected under the EU’s Natura 2000 scheme. Yet few forests in Europe have a bigger paranormal reputation.

The legend has identifiable authors. Romanian accounts credit the Cluj biologist Alexandru Sift with the first systematic study of the forest, which they date variously to the early 1950s, the late 1950s or the decade 1950–1960; he is said to have photographed hazy figures among the trees that he had not seen with the naked eye. His archive reportedly vanished after his death in 1993, and the few pictures said to survive appeared only in a 1995 book by the parapsychologist Adrian Pătruț – so the images have never been independently examined. Then on 18 August 1968 Emil Barnea, a construction technician and former army officer, was picnicking with his partner and two friends in Poiana Rotundă, a round, grassy clearing in the western part of the wood, when they saw what they described as a silvery disc gliding silently overhead. Barnea took several photographs; one appeared in Romanian newspapers that September and was soon reprinted around the world as one of the classic UFO images of the era. The director of the Cluj observatory dismissed it as a hoax or a weather balloon.

In the 1970s and 1980s the chemist Adrian Pătruț wrote about the forest as a centre of “psychic energy”, and his work – which Romanian Wikipedia’s editors and skeptics describe as pseudoscientific, built on anecdote rather than measurement – helped cement the idea of Hoia-Baciu as a place where the ordinary rules fail. From there the stories multiplied: a shepherd said to have vanished with a flock of 200 sheep (the folk explanation for the name), a girl who disappeared and returned years later without memories, magnetic anomalies that drain phone batteries. None of these tales has a documented victim, date or report behind it.

Since the 2000s the forest has become an international paranormal destination, filmed for Destination Truth, Ghost Adventures, the Swedish series Spökjakt and Expedition X, and featured in British newspapers’ Halloween lists. Local guides now run night walks, and the Cluj municipality has wrestled with how to balance the forest’s new fame against illegal logging and pressure from the expanding city.

Visitors and TV crews report lights and orbs at night, a feeling of being watched, sudden anxiety or nausea, burns or rashes, lost time, cameras and phones failing, and voices among the trees. The forest is also known for oddly bent and twisted tree trunks, which many see as a sign that something is wrong.

Most stories gather around Poiana Rotundă, the round clearing where Barnea took his 1968 photographs and where, according to legend, nothing will grow. Night walks also visit groves of contorted trees deeper in the wood.

Hoia-Baciu has been the subject of TV episodes, a crowdfunded local documentary and the horror video game Deadly Quiet. Cluj’s guides sell it as “the Bermuda Triangle of Transylvania”, and Halloween night walks are now a fixture.
