About Sovata
A spa town in Mureș County whose main attraction is a lake that formed by accident. On 27 May 1875 a salt massif collapsed and Bear Lake appeared: 40,000 square metres, 18 metres deep, with an average salinity of around 300 grams per litre. It is the largest heliothermal lake in the world, and the phenomenon is what makes it worth the trip.
Heliothermy works like this: a thin layer of fresh water from the streams feeding the lake sits on top of the dense salt water and acts like the glass of a greenhouse. Sunlight passes through and the heat gets trapped underneath, so the water is cooler at the surface than a metre and a half down. The figures differ a lot between sources: 25–29 °C at the surface, and anywhere from 32 to 45 °C below, depending on who measured and when. The operator’s press releases repeat 28 °C and 39 °C, but a geography study puts it at 32–34 °C at 1.5–2 m. The reading for the day is chalked on a board at the strand entrance — check that instead.
Region & access
- Mureș County, on DN13A between Bălăușeri and Praid. You come off E60 from Târgu Mureș or off DN13 from Sighișoara.
- No train. The Blaj–Târnăveni–Praid line has been suspended since 2019 and has not been reopened. The only rail left is the tourist narrow-gauge from Sovata to Câmpul Cetății.
- Târgu Mureș 40 km, Sighișoara 47 km, Brașov 113 km, Cluj-Napoca 114 km. Nearest airport: Transilvania Târgu Mureș, 60 to 68 km, with nine new routes added in spring 2026.
How the water is layered
- The first two metres hold 10 to 15 g/l of salt. Then there is a jump: between 2 and 3 metres the concentration rises to about 240 g/l, and towards the bottom it reaches 250 to 300 g/l.
- That jump is what produces the heat trap, and it is also why you float without effort once you are past the surface layer.
- The lake bottom holds chlorinated-sodic sapropelic mud. At around 1.5 m depth the water also contains natural oestrogen and progesterone, produced by the brine shrimp Artemia salina.
What it is used for
- The resort profile is rheumatic and locomotor — arthrosis, spondylosis — plus gynaecological conditions, including sterility, which is the indication Sovata is best known for historically.
- Also dermatological and respiratory conditions. The Ensana hotels — Sovata 4 stars, Brădet 4 stars superior, Ursina 3 stars, the former Făget — have indoor pools filled with salt water drawn from the lake.
- Guests at those hotels get free access to the Bear Lake and Aluniș strands in summer, which changes the arithmetic if you were going to pay 55 lei a day anyway.
Three lakes, not one
- Ștrandul Lacul Ursu, run by Ensana Health Spa Hotels Sovata, is the main one and is open to the public whether or not you are staying in the resort.
- Ștrandul Lacul Aluniș opened in early May 2026 and has clay mud rather than sapropelic. It is the one that works in the weeks before Bear Lake opens.
- Ștrand Lacul Negru, at the Aluniș spa complex, runs 10:00–18:00. Its rates are simply blank on the operator site.
- The season is short. Bear Lake opened on 26 June in 2026 and closes around mid-September depending on the weather. If you come in May or early June, Aluniș is your only option.
- What the 55 lei covers is access, nothing else. Sun loungers, food and parking are separate; street parking runs about 15 lei a day, though that figure comes from visitor reports rather than a published tariff.
- If you are here for treatment rather than a day out, the hotel route makes more sense than the strand. The Ensana pools use the same lake water indoors, are available year round, and come with a treatment base — whereas the lake itself is a summer proposition with a fixed daily rhythm you have to work around.
- A practical note on the mud: the sapropelic mud is on the lake bed, not laid out for you in tubs the way it is at Techirghiol. What you get here is the water and the thermal stratification. If a mud cure is the reason for the trip, the coast is the better match.
The two-hour break
- Bear Lake strand: daily 10:00–18:00 through the season.
- There is a compulsory break from 13:00 to 15:00. Everyone gets out of the water, though you may stay on the strand. If you leave the strand during the break, you pay a new ticket to come back in.
- That break splits the day in two and is the thing most visitors do not know in advance. Plan lunch around it rather than against it.
- Ștrand Lacul Negru at the Aluniș complex: 10:00–18:00. Opening dates for the 2027 season are not published this far out — check before travelling in early summer.
Read on 1 August 2026
- Lacul Ursu, 2026 season: 55 lei for adults, 40 lei for children. The rate is the same on weekdays and at weekends — there is no weekend surcharge.
- Multi-entry tickets valid across several days exist, but their price is not published. A pensioner rate is not published either.
- Ignore lacul-ursu.ro. The site still shows a 2014 tariff of 25 and 20 lei and has clearly been abandoned. The current figures come from the operator and the 2026 press.
- Aluniș 2026 rates are not published; in 2025 they were 40 lei for adults and 30 lei for children, so expect something in that region.
- For context on what else is nearby, the Praid salt mine — the obvious pairing at 10 km — is closed. It flooded in 2025 and was still under an orange seismic alert in July 2026, with no confirmed reopening.
Good to know
- Take the Praid salt mine out of your plan. It has been flooded since 2025 and there is no confirmed reopening date. What remains open nearby is the Salt Mountain and the Corbului gorge.
- Bear Lake only opens at the end of June. In May and June the resort still works, but through Aluniș, which is a different and less spectacular experience.
- The 13:00 to 15:00 break is enforced. Budget for it, and remember that stepping off the strand during it costs you a fresh ticket.
- You need a car. There is no train to the resort, and the alternative is a minibus from Târgu Mureș.
- Water this saline is hard on the skin and the eyes. Rinse off afterwards, do not go in with fresh cuts, and treat the warm layer below the surface the way you would treat a hot bath rather than a swimming pool.
- Bear Lake is the reason to come, but it is a small lake with a fixed capacity and a two-hour break built into every day. In July and August it fills quickly. Arrive at opening, or plan a hotel stay so the pools are available to you outside strand hours.
