Hisaralan Thermal Springs (Hisaralan Kaplıcaları)

What to expect

Hisaralan is a small village in Sındırgı district, in the forested hills of south-east Balıkesir where the province meets Manisa and Kütahya. A few kilometres south-west of the village, very hot water comes out of the ground in a valley of red pine. The Balıkesir culture and tourism directorate lists the springs at 115-208°F46-98°C, which puts the hottest vents close to boiling, and says the water flows out by itself at about 172 litres a second. It classes the water as a fluoride-bearing sodium bicarbonate type.

That much hot water has more uses than bathing. The directorate’s description of the thermal tourism centre mentions a Ministry-certified four-star hotel and several pensions, and in 2012 work began on a pipeline to carry Hisaralan water to Sındırgı to heat about 3,000 homes and supply greenhouses. For a visitor, though, Hisaralan means one main thing: a quiet spa hotel in the woods, with pools of cooled spring water and not much else around it.

This is not a wild spring. There is no natural pool to walk to, and the source water is dangerously hot. You bathe in the hotel’s pools or in a pension’s small bathhouse.

Obam Termal Resort

Obam Termal Resort Otel & Spa is the largest place to bathe and the hotel OpenStreetMap shows in the thermal valley. Its main features:

• Thermal pools: separate men’s and women’s pools, indoor and outdoor, with a direct passage from each indoor pool to its outdoor pool. Each outdoor pool is 185 m², 1.45 m deep on the men’s side and 1.40 m on the women’s.
• Water temperature: the hotel sets its pools to 86-90°F30-32°C in summer and 97-100°F36-38°C in winter.
• Hours: the outdoor thermal pools are open every day from 8 a.m. to 10 p.m.
• Other facilities: a private family pool, a traditional Turkish hamam, a thermal jacuzzi, a steam bath, saunas, massage and a salt room.
• Rooms: every room has thermal water in the hot taps.

The hotel cites a 2007 Ministry of Health medical evaluation report that describes its water as a mixed, fluoride-bearing thermomineral water with total mineralisation of 1,266 mg per litre.

Getting there

Sındırgı lies on the Balıkesir to İzmir highway, about 63 km (39 miles) south-east of Balıkesir. From Sındırgı, the road east toward Simav climbs into the hills; the thermal area is 17 km (11 miles) from town and about 3 km (2 miles) south-west of Hisaralan village itself. The hotel has a free open-air car park.

Without a car, take one of the buses on the Simav to İzmir route, which the tourism directorate says pass the thermal area, or a village minibus from Sındırgı. Balıkesir has the nearest large bus station, and İzmir has the nearest major airport.

When to go

The pools are open all year. Winter is the classic season for a Turkish spa stay, and Obam Termal raises its pool temperatures to 97-100°F36-38°C from autumn. Snow is possible in the hills in January and February; the hotel mentions guests sitting in the outdoor pools while snow falls. Summer is hot in the valley, and the pools are kept cooler to match. Weekends and bayram holidays are the busiest times, so come midweek if you can.

Prices and booking

Obam Termal does not publish prices. Its frequently asked questions page says rates change with the season and occupancy and directs guests to the reservations line, 0266 541 10 10. It offers half board (breakfast and dinner) and full board, but no all-inclusive package, and tea is served free in the lobby through the day, with a café treat at 4 p.m. Cancellation is free up to three days before arrival and charged after that. The hotel accepts Visa and Mastercard, and foreign currency at reception. Pets are not allowed.

Ask before you go whether day visitors can use the pools, as the hotel does not mention day passes. Turkish prices change often.

Bathing culture

Hisaralan follows the customs of a Turkish family spa. The shared thermal pools are single-sex, and you wear a swimsuit in them. In the hamam, wear a swimsuit or a cotton peştamal; nudity is not the custom in shared areas. Couples and families who want to bathe together book the private family pool. Shower before you go in and keep soap out of the pools.

Many guests come for a course of baths. The Balıkesir tourism directorate recommends a cure of about 21 days, and no less than 15, ideally with a doctor setting the length. Expect early nights and a quiet dining room rather than entertainment.

Where to stay nearby

The hotel is the main base, and the tourism directorate notes pensions around the thermal area as cheaper options. Sındırgı town, 17 km (11 miles) away, has shops, pharmacies and simple lodging. The Emendere spring at Ilıcalı village, 7 km (4 miles) from Sındırgı, has its own thermal hotel, Eman Termal, which has been open for about 16 years.

Safety notes

• Scalding water: The source water reaches 208°F98°C. Never touch outflow pipes, channels or puddles near the vents, and keep children well away from them.
• Short soaks: Even at 97-100°F36-38°C, keep sessions to about 20 minutes, drink water and get out if you feel faint. People with heart conditions or high blood pressure, and pregnant women, should ask a doctor first.
• Earthquakes: Sındırgı is in an active seismic zone. A magnitude 6.1 earthquake on August 10, 2025 killed two people, and a magnitude 6.0 shock on October 27, 2025, centred 4 km (2.5 miles) east-south-east of Sındırgı, injured 68 and brought down buildings in the town. Between the two, a magnitude 4.9 shock on September 7, 2025 destroyed two houses in Sındırgı. Learn the exits in your hotel and follow AFAD advice if you feel a tremor.
• Forest fires: The valley is surrounded by pine forest. Do not light fires or drop cigarettes outdoors in summer.

Nearby stops worth adding

Sındırgı is known for Yağcıbedir carpets, hand-knotted by the Yörük communities of the area in deep blue, red and white, and you can see them in the town’s workshops. The district revived its oil-wrestling festival in 2016. Simav, over the hills to the east in Kütahya province, is another major thermal area. On the way back toward the coast, Gönen Thermal Springs in the north of Balıkesir makes a contrast: a spa in the middle of a town rather than in the forest.
