A hill of petrified snails of various shapes and sizes. The stone shells of some snails that lived in these places a long time ago. At the time when here on the place where the Apuseni are today there was a vast sea called Tethys. Under pressure and under the action of time, one of the large banks of snail shells petrified.

If you look carefully at the rocks with petrified snails, you can easily notice various shapes and sizes - dozens of species of snail-pebbles cemented together in the gray rock. When you touch them, you can still feel the fine spiral on the back of the shells.

Leaving Arieseni, go towards Campeni 35 kilometers to the Mihoiesti dam - where Ariesul Mare and Ariesul Mic met to form Ariesul. Here you will also find a pointer to the famous Gaina mountain, where the Girls' Fair is held every year. Cross the dam and follow the paved road until you pass through the village of Vidra until on the right you will meet an information board 'Snail Hill' - approximately 20 kilometers from the dam. Photograph the stone snails on the side of the road and those above. And if you continue to climb, you will find an amazing viewpoint for the landscape of Vidra commune.
