About this experience
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.

Unirea Salt Mine
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)
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.

An Unbelievable Sight
The salt mine was unbelievable. Well worth the time it took to get there. Victor our guide was on time, had a very nice SUV and was very professional. It was a very nice day.

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!

Wow factor
This trip is great, something different to the normal. The salt mine definitely has that wow factor and the mud volcanoes are really cool 😎 The tour guide was friendly and drove safe. Definitely recommend this tour.

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"

Why this scores 72
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Muddy Volcanoes & Salt Mine - Private Tour: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Bucharest.
How much does Muddy Volcanoes & Salt Mine - Private Tour cost?
+
Prices start at $174 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Bucharest usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Muddy Volcanoes & Salt Mine - Private Tour take?
+
Plan for about 11 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Bucharest is not rushed.
Is Muddy Volcanoes & Salt Mine - Private Tour worth it?
+
It holds an Outty Ranking of 72 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.9/5 across 22 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Bucharest, and how flexible the cancellation terms are.
Can I cancel or reschedule Muddy Volcanoes & Salt Mine - Private Tour?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Muddy Volcanoes & Salt Mine - Private Tour suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 11-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Muddy Volcanoes & Salt Mine - Private Tour?
+
Around 8 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Bucharest can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Bucharest and add a light layer if any part of the 11-hour experience runs outdoors or after sunset.
Where does Muddy Volcanoes & Salt Mine - Private Tour start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Bucharest within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Bucharest?
+
On Outty we rank every Bucharest experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include The Real tour of Communism, Bucharest Highlights Walking Tour, Top Gear Road, Small-group max 7 pax with Pick-up, Transfăgărăşan. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Bucharest?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Bucharest?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
