Niebieskie Źródła Nature Reserve

Right on the eastern side of Tomaszów Mazowiecki. This reserve is a karst spring, one of the most interesting in Europe. From the cracked Jurassic limestone, water gushes out, taking on a blue color - depending on the light (more or less sun) different shades! Extraordinary!

Niebieskie Źródła Nature Reserve is a picturesque protected area in Tomaszów Mazowiecki, known for its unique blue-green karst springs. The water erupts sand from the bottom, creating extraordinary visual effects, and its constant temperature is around 9°C. The reserve is a refuge for around 75 species of birds, such as the kingfisher and mute swan, and many rare plants. The area is crossed by educational trails, and nearby is the Pilica River Open-Air Museum.

Under the water surface there are blue water bubbles. Well visited spot.
