If you think that discovering prehistoric mysteries requires traveling to the caves of France or the rock complexes of Spain, you are deeply mistaken. A true archaeological and visual treasure, whose age reaches tens of thousands of years, is hidden in the dense forests of Galicia.
RBC-Ukraine explains why this location resembles the sets of a Hollywood fantasy film and how to find this mysterious "portal to the past."
Here, the stone forms bizarre columns that resemble giant ribs of some mythical creature, while the atmosphere itself makes your skin crawl with goosebumps.
This is the legendary Pryima grotto — a unique Neanderthal settlement considered one of the oldest monuments of human history in Ukraine.
Cosmic architecture of nature: What the grotto looks like
The Pryima grotto is not just a hole in the rock; it is a true three-level karst complex. The rock formation is made of ancient limestone that, under the influence of wind, water, and time, has taken on entirely surreal shapes.
When you approach the grotto from below, it feels like you are standing before the jaws of a giant monster or inside the set of the film Alien. The stone pillars supporting the vaults of the upper caves are thin, curved, and intertwined in a way that resembles petrified roots of ancient trees or anatomical bones.
The complex consists of several levels. The lowest level contains small niches, while the second and third levels form spacious viewing platforms and deep caves, offering a fantastic view of a green canyon.

Neanderthal dwellings: What archaeologists discovered here
Pryima is not only about stunning social media photos. It is a site of global archaeological significance. At the end of the 20th century, during excavations led by Professor Leonid Matskevyi, a sensational discovery was made here.
Archaeologists uncovered the first Neanderthal settlement in Galicia, dating back approximately 45,000–46,000 years.
Findings in the grotto included:
- Remains of an ancient hearth and burnt animal bones from prey hunted by prehistoric humans (including mammoths and cave bears).
- Flint tools, including pointed implements and scrapers.
- Unique bone remains of Neanderthals themselves, which became a major breakthrough in the study of human settlement on the European continent.
Scientists suggest that the grotto served as a seasonal hunting camp in winter: its elevated position made it easier to spot game in the valley below, while the rock formation provided natural protection from cold winds and wild animals.
How to get there and avoid getting lost in the forest
The grotto is located near the town of Mykolaiv (Lviv region), in the Pryima area. The route there is a small adventure in itself, as the site is well hidden from casual visitors.
By car: take the Kyiv–Chop highway to Mykolaiv. In the town, turn left toward the quarries and the village of Rozvadiv, then continue along a field road toward the forest. It is better to leave the car at the forest edge, as the trail to the grotto is quite steep and muddy.
On foot from Mykolaiv: from the town center, it is about 3–4 kilometers to the grotto. The trail passes through a stunning beech-hornbeam forest with deep ravines.
Important tip: be sure to download offline maps (such as Maps.me or Google Maps with a pinned location, Pryima Grotto), as mobile signal often disappears in the forest ravines, and there are no official signposts or marked tourist trails yet.

Tips before your trip
Footwear matters. The final ascent to the grotto is very steep. If it rained the day before, the ground turns into a slippery surface. Choose trekking sneakers or boots with good grip.
A flashlight is useful. If you plan to look deeper into the cave passages on the upper levels, your smartphone light may not be strong enough.
Respect the history. The grotto is a unique natural and archaeological monument. Please do not leave "I was here" inscriptions on 40,000-year-old rocks and take all your trash with you.
The Pryima Grotto is an ideal option for a one-day weekend trip from Lviv. If you want to feel like a discoverer and see a location that will completely change your perception of tourism in the Lviv region, pack your backpack and head to the forests near Mykolaiv.
