From the castle hill there is a view of the East Slovakian lowlands, you can see the town of Michalovce and Zemplínská šírava.

Hradný vrch is occupied by the Viniansky hradný vrch Nature Reserve, declared in 1984 on an area of 51.96 ha with the 4th degree of nature protection. The nature reserve was expanded in 1988 in order to protect the southern slopes of the castle hill of Vinianske castle inhabited by thermophilic forest-steppe and forest communities with the occurrence of rare species of flora and fauna.
