Grunjul, the little white mountain, rises lonely from the bed of the Slănic River, right on the road leading to Lopătari. The name could mean lump, or narrowing, or it could refer to its gritty appearance. It's one of the most beautiful and strange sightings in the scenery, unlike anything you've seen in Romania.
At first glance it looks like salt, but it is made of volcanic tuffs on the Thethys seabed covered with white marl, whose hardness has allowed it to withstand the erosive action of wind and water well enough to remain, phallically, in the middle of them.
However, it is only in the last hundred years, since there is hard data, that Grunjul has lost much of its size. At the beginning of the last century, there was a fairly large plateau at the top, which housed a pub and, periodically, even the village horeca.
With the status of reservation Geologically, also nicknamed White Stone, Grunjul still dominates from afar, from the height of its almost 20 meters, the landscape of the Slănic and Jghiabului valleys in the Mânzălești area. A stone's throw from the White Stone La Grunj the museum awaits you Man Time.
