Dealul cu Lilieci Cernătești, Nature reserve in Cernătești, Romania.

Dealul cu Lilieci Cernătești is a 10.59-hectare IUCN category IV nature reserve in Cernătești commune, Buzău County. It lies on Dealul Săpocii, in the right floodplain of the Slănic valley, where a strip of wild lilac (Syringa vulgaris) about 1 km long and only 8–15 m wide grows among downy oak, Turkey oak and Hungarian oak.

The area received official protection in 2000 to preserve the wild lilac plant species found there. This designation marked an important moment in safeguarding the botanical diversity of the region.

The name "Dealul cu Lilieci" comes from the wild lilac (Syringa vulgaris), which grows here in a band almost 1 km long and only 8–15 m wide on the slope of Dealul Săpocii. The reserve is a monument of nature, described as the only one of its kind in Buzău County, and visitors come in late spring when the shrubs are in bloom.

The reserve sits along county road DJ203K between Săpoca and Vlădeni, with signs marking the way from Cernătești church. Wear sturdy shoes since the terrain is uneven and ground conditions vary depending on the season.

The wild lilac strip runs almost 1 km along the slope but is only 8 to 15 m wide, a narrow band of shrubs on Dealul Săpocii. The reserve is listed as a natural monument, the only one of its kind in Buzău County.
