Bodajki-tó, Natural lake in Fejér County, Hungary.

Bodajki-tó is a natural lake in Fejér County featuring clear water with green vegetation growing around its shores. The body of water has a moderate depth and remains accessible for swimming and water activities throughout the warmer months.

The first expert report on the lake's water was drawn up in 1765, noting large amounts of soap clay that let Bodajk women whiten laundry without soap. Development as a bathing resort began in the 19th century, long leased and improved by lawyer Szekrényessy József (1811–1877). After coal mining dried the springs, the lake was restored in 1992 and fed from a 170 m well.

The lake serves as a gathering place for locals during summer months, drawing people who enjoy fishing and outdoor socializing by the water. The surrounding banks and grassy areas become natural meeting spots for residents seeking time together in the open air.

The lake is best visited during summer months when water temperatures are warmest and swimming is most enjoyable. Accommodation options nearby offer flexibility for visitors who wish to spend time exploring the area and its surroundings.

The lake's water was described in 1765 as containing so-called soap clay, which let the women of Bodajk wash their clothes white without soap or detergent. The same report noted magnesium, carbonic acid, soda salt, iron and lye salt in the springs feeding the lake.
