Mists curl through the ancient beech forests of Vihorlat as if the mountains themselves are breathing. The trail to Sninsky kamen climbs through a cathedral of green, where the leaves of centuries-old trees filter the light into a soft emerald gloom. At the summit, a volcanic rock formation overlooks the still waters of Morske oko, a lake that fills a crater carved by fire and ice. Woodpeckers tap in the silence below. Wild boar root through the underbrush. This is a landscape shaped by volcanoes and softened by time, where the forest floor is thick with ferns and the air tastes of damp earth and pine.
Protected Landscape Area Vihorlat is a volcanic area in the Slovak Republic. It is located in the regions of Presov and Kosice in the Eastern Carpathians. The area is bounded by the towns Remetske Hamre and Zemplinske Hamre. Vihorlat Mountain has been a protected area since 1973 and with an area of 17,480 ha it is the smallest protected landscape area in Slovakia.

Morske Oko Lake and Sninsky Kamen
Protected Landscape Area Vihorlat includes several natural reserves such as Lake Morske oko (Marine Eye) and the highest mountain peak, Vihorlat, which reaches an altitude of 1,076 m. Morske oko is the largest glacial lake in eastern Slovakia, sitting at 618 metres altitude with a maximum depth of 25 metres. A walking trail from the Remetske Hamre car park reaches the lake in 45 minutes. Swimming is popular in summer, with water temperatures reaching 20 degrees Celsius. The lake is surrounded by ancient beech forests that display spectacular autumn colours, drawing photographers and leaf-peepers from across the country. The area also includes Durova mlaka, a typical circular crater in the Vihorlat mountains, where you can find a protected peat bog with specialised plant species that have adapted to the acidic, waterlogged conditions. One of the most iconic features is Sninsky kamen (Snina Stone), a natural rock formation about 20 m high that was created by cooled lava. The summit offers panoramic views of the surrounding forests, the lake below, and on clear days even the distant peaks of the High Tatras to the north-west.
Hiking Trails and the UNESCO Primeval Forest
Protected Landscape Area Vihorlat offers lots of trails. The most popular is the trail that leads from Lake Morske oko through Sninsky kamen and ends at Snina ponds. The trails are open to the public since 1984 and are well marked with standard Slovak hiking signs. The full loop from the car park to the lake, up to the rock formation, and back down through the forest takes about three hours at a relaxed pace. The terrain is moderate, with some steeper sections near the summit, but the path is well maintained and suitable for hikers with a reasonable level of fitness. Along the way, interpretive panels describe the volcanic history of the area and point out notable tree species. Kyjovsky prales, a primeval beech forest in the Vihorlat Mountains, was proclaimed in 2007 by UNESCO to be a World heritage Site due to its comprehensive and undisturbed ecological patterns and processes. This old-growth forest has never been logged, and walking through it feels like stepping back in time. Fallen trees are left to decompose naturally, creating a rich habitat for fungi, insects, and small mammals.
Wildlife and Biodiversity
Vihorlat protects about 35 species of plants. The most valuable are the Spring Snowflake, Soldanella carpatica and Telekia speciosa. Vihorlat is also home to 2,000 kinds of vertebrates, 100 species of birds and several species of carnivores including wolves, lynx, wildcat, and otter. The forests provide an important corridor for large mammals moving between the Eastern Carpathians and the rest of Slovakia. The birdlife is especially rich, with black storks, eagle owls, and several species of woodpecker all breeding within the protected area. The best time for wildlife watching is early morning or late evening, when the animals are most active. The Vihorlat area remains one of the least visited protected landscapes in Slovakia, meaning that those who make the journey often have the trails and viewpoints almost to themselves.
