Being declared a monument of nature for more than five decades, Piatra Teiului is an isolated rock, situated at a distance of about 44kms North-West far from Bicaz, near the viaduct in Poiana Largului village, in the actual basin of accumulation lake – Izvorul Muntelui. The access to the rock is made on the route Piatra-Neamţ - Bicaz – Borsec (Vatra Dornei).
Poiana Teiului rock has been declared monument of nature for more than five decades and it is set in ‘’Coada Lacului’’(‘’The End of the Lake’’), the place where the four roads from Moldavia and Transilvania are meeting, at an altitude of 508 metres.
Here we can study the process of sedimentation from the geological past of this area.
In the most part of the year it is surrounded by the accumulation waters, being the best observed from the viaduct that crosses the lake.
The rock has a height of 23 metres. It has been found, at a closer analysis that in the composition of the rock there is a rich fossil fauna sarmatica.
Initially, the stone was called ‘’the Devil’s Stone’’, the actual name being taken after a lime tree grew on it.
Called by the natives the Devil’s Stone, This monument of nature fits many legends. They say that Piatra Teiului rock changes its place every night and when the devil is coming, to it, all the fires from the neighbour localities are dieing and all the animals, from birds to four-legged are in silent.
Another legend, says about an ogre who was stealling the village’s girls and taking them on the mountain plate transforming them into weird looking stone figures.
