Muddy Volcanoes: A Guide to Romania's Otherworldly Natural Reserve

In the hills of Buzău County, a strange and captivating landscape awaits. The Muddy Volcanoes, known locally as Vulcanii Noroioși, are not fiery peaks but small, cone-shaped mounds that ooze cold mud and bubble with natural gas. This protected geological and botanical reservation offers a glimpse of a terrain that feels more lunar than terrestrial, making it a must-see for nature lovers and photographers travelling through Romania.

What Are the Muddy Volcanoes?

The muddy volcanoes are created by natural gas rising from depths of around 3,000 metres. As the gas pushes upward, it forces clay, salt water, and minerals to the surface, where they form small cones and pools. Unlike real volcanoes, the mud here is cold and the eruptions are gentle, with gas bubbles constantly breaking the surface. Over time, the escaping mud builds up cone-shaped formations that can grow several metres tall, though they are constantly changing shape.

The Two Main Sites

The reservation is divided into two main areas, Pâclele Mari (the Large Muddy Volcanoes) and Pâclele Mici (the Small Muddy Volcanoes). Pâclele Mari features broad, flat craters filled with grey mud and continuous gas bubbles, creating a surreal, almost desolate scene. Pâclele Mici, about two kilometres away, showcases more defined, miniature cones that resemble tiny volcanoes, some only a few centimetres high. Both sites are connected by a marked walking trail, and visitors can observe the dynamic processes up close.

Planning Your Visit

The Muddy Volcanoes are located near the village of Berca, approximately 40 kilometres from Buzău city. The site is signposted from the main road, and the final stretch is an unpaved track suitable for most cars in dry weather. There is a small car park at each entrance. No public transport serves the reservation directly, so a private vehicle or organised tour is the best option. The site is open year-round, but spring and autumn offer the most pleasant temperatures for walking. Summer visits are best early in the morning or late afternoon to avoid the heat.

What to Bring and Expect

• Footwear: The ground is muddy and slippery, so wear sturdy, waterproof shoes or boots you don't mind getting dirty.
• Sun protection: The area is exposed with little shade, so bring a hat, sunscreen, and plenty of water.
• Camera: The unique terrain and contrasting colours make for striking photographs, especially in the soft light of early morning or late afternoon.
• Caution: Stay on marked paths and avoid stepping on the fragile mud formations. The mud can be deep and sticky in places.

Why It's Worth the Trip

The Muddy Volcanoes are a rare natural wonder, one of only a few such sites in Europe. The stark, barren landscape dotted with grey cones and glistening mud pools offers a stark contrast to Romania's lush forests and mountains. It's a place that feels frozen in time, where the earth itself seems to breathe. For travellers seeking off-the-beaten-path destinations, this geological curiosity delivers an unforgettable experience.
