A feature of the forest is the abundance of climbing plants: wild vine, hops, tendril forest and not least liana Greek (Periploca graeca) that gives an aspect Mediterranean forest.

Sand dunes (dunes Omer) in the west of the village Caraorman, about 500 m from it, are the dunes of fine sand, which can be found only in three places in Europe. These sand dunes are placed transvesal Caraorman the direction of flow of the Danube with the cord portion Letea is initially blocked the Gulf of Tulcea, turning it into a lagoon, which later spawned clogged and Delta .
Sand dunes of marine origin have heights up to 7.9 m and are semimobile, the wind carrying sand and grouping it around the plants you can. Dune called "Cuibisca" (the name comes from the nearby lake Cuibida) 20 years ago was very high, because the top of it was a tree that has set the sand around him. But after the tree from top to dry, wind swept sand dunes and reduced height for stretching them.
