Description

Join us on an unforgettable journey through two of Romania’s most fascinating natural attractions. Our first stop is the Slănic Prahova Salt Mine, one of the largest salt mines in Europe. Located 208 meters underground, this colossal mine impresses with its cathedral-like chambers, constant temperature of 12°C, and natural air rich in salt aerosols—known for their therapeutic properties. Marvel at salt sculptures, enjoy games and exhibitions, or simply breathe in the healing air of this underground wonder. Next, we head toward the Mud Volcanoes, a rare geological phenomenon where gas eruptions push up salty mud, creating a lunar-like landscape. Located in Buzău County, this natural site offers a surreal experience—tiny craters bubbling with cold mud in a barren, dramatic setting that feels out of this world. Whether you’re a geology enthusiast, a photographer, or just looking for a unique escape, this tour promises memories that will last a lifetime.

Itinerary

Unirea Salt Mine
Admission not included120 min

Slanic Prahova Saline is the largest salt mine in Europe. Now the old mine is currently open to the general public, being used as a leisure place. Slănic Prahova Saline is located at a depth of 208m, on an area of ​​53,000sqm and was opened for visit after 1970. The saline consists of 14 rooms, in the form of a trapeze, having an opening at the base of 32 meters, the tray, 10 meters and a height of 45 meters. The excavated space is 2.9 million cubic meters of salt. Underground is also a sanatorium for asthmatic patients who are provided specialized medical care. The ventilation of the mine is natural, with a constant temperature throughout the year of 12 degrees Celsius. Inside salt mine we visit the Supernova Planetarium which is the largest and most performant planetarium in Romania with the largest spherical screen of 16 m diameter, max. 200 seats, 4K laser projectors, super-ergonomic armchairs. We look forward to the most fascinating immersive experience in Romania.

Vulcanii Noroiosi (Muddy Volcanoes)
Admission not included60 min

Muddy Vulcanoes is a geological and botanical reservation located in Buzău County in Romania. Its most spectacular feature is the mud volcanoes, small volcano-shaped structures typically a few metres high caused by the eruption of mud and natural gases. As the gases erupt from 3000 metres deep towards the surface, through the underground layers of clayand water, they push up underground salty water and mud, so that they overflow through the mouths of the volcanoes, while the gas emerges as bubbles. The mud dries off at the surface, creating a relatively solid conical structure resembling a real volcano. The mud expelled by them is cold, as it comes from inside the Earth's continental crust layers, and not from the mantle.

Amazing Sights, friendly guide

This is a long day but an incredible one to 2 awe inspiring sites. Pedro picked us up on time from our hotel and was very friendly and easy to talk to. His English is excellent. The first stop was the Salt Mines and we had never seen anything like it. It is magnificent. We then had a good lunch with Pedro suggesting local foods we may enjoy, and we did. The Muddy Volcanoes were a naturally occurring phenomenon and very much how you imagine the surface of the moon would be like. Pedro make a video of the site for me using my phone as I’m not great with technology. We had a wonderful day. Thank you.

Visit to Romania’s muddy volcanoes

An excellent visit to the muddy volcanoes, east of the underground salt mine! The landscape is phenomenal, like you are on the moon, where there were numerous circular shaped craters with bubbling soft warm mud!

Salt mine is ok but the volcanoes...

I definitely would recommend the visit to the mines. It was a different experience for those who has never been in a similar place. The environment is amazing. But, I am not sure I would recommend the volcanoes tour if someone asked me. It is a long travel in a windy road which makes my wife and I get sick. Upon arriving there it is a unique experience as long as I have never seen a mud coming from the bottom of the earth. But, I would choose a different think to do mainly because it is far and nothing "ooh"

Sebastian is THE PERFECT guide, highly recommend the trip!

When checking the Viator site for something unique to visit in Romania, we were deciding between Dracula castle and our trip (Salt Mine and Muddy Volcano). We are glad that we have made our choice. First, I would like to express our deep gratitude to our guide Sebastian, who makes our journey a perfect one. He arrived on time to pick us at the hotel, spoke perfect English, was very polite and attentive throughout the journey, and was also very knowledgeable about Bucharest, the salt mine and the muddy volcano. He can even remember all the years when historical events happened! We went on a Thursday so both places were not very crowded. The salt mine is so unique and magnificent to see. It's very spacious down there (50 meters in terms of vertical height and 150 meters underground). We took many lovely pictures there and learned a lot about the history of the mine from Sebastian. A gentle reminder is that the salt mine is quite cold and windy (12 C degree throughout the year), so remember to bring a jacket with you! The muddy volcano is also very unique. We arrived there around 4 pm and we were the only group of tourists there (heard from Sebastian that Dracula Castle would be very crowded so we felt lucky to have made our choice), so we had lots of freedom to take pictures and walk around. Btw, the entry is cash only and we didn't bring any cash. Sebastian kindly bought the tickets for us which was really considerate. Overall, this whole trip is an excellent experience and I would recommend anyone to try it if you would like a day trip outside Bucharest!

Highly recommended!

Our tour guide, Octavian, was friendly and very informative. Because of rain, we didn't visit the muddy volcano, instead, Octavian suggested wine tasting after which we ate the most delicious meal in all of Romania. It was a fun and memorable day.

Fantastic tour, highly recommend.

Fantastic day out with our tour guide, Victor. We had an amazing day, learnt so much and Victor was brilliant throughout. We loved both sites, the Salt Mines was just unbelievable and the muddy volcanoes were unique. Stopped for lunch in a lovely winery, highly recommend this tour. Thank you for making our day one to remember.
