The Ahja is a 104 km long river in south-eastern Estonia that rises from Lake Erastvere in Põlva County — the largest right-bank tributary of the Emajõgi. Along the Taevaskoda stretch the river's banks are formed by reddish sandstone cliffs up to 22 metres high — 'Suur Taevaskoda' (Great Taevaskoda) and 'Väike Taevaskoda' (Little Taevaskoda) are the tallest sandstone outcrops in Estonia. The sandstone bed filters the river water clear within just a few days, even after high water.

History & culture
The Taevaskoda cliff was a sacred site of the ancient people, mentioned in 13th-century writings; the place's cultural significance has been continuous from prehistoric times through to the national awakening. Lydia Koidula and Friedrich Reinhold Kreutzwald described the Taevaskoda sandstone cliffs in their writings, binding the place to Estonian national identity. The rare moss and bryophyte flora growing on the sandstone outcrops is under botanical protection.
Seasonal changes
In spring, in April, the Ahja runs high with peat-coloured water; within a short time the water clears thanks to the filtering effect of the sandstone bed, and by summer the river becomes the clearest in Estonia.
