About Vihorlat Mountains#

The Vihorlat Mountains are a volcanic mountain range in eastern Slovakia and form part of the Inner Eastern Carpathians. The range is noted for its beech and mixed forests, volcanic landforms and small mountain lakes.

The area is popular for hiking and nature tourism, with marked trails that lead to summits and viewpoints and to the small volcanic lake Morské oko, a well-known natural attraction. The landscape is forested and supports a range of Central European mountain flora and fauna.

The mountains originated from volcanic activity that left crater lakes and basalt formations, and their forests have long been managed and protected; parts of the range are included in official protected landscape areas to conserve biodiversity and natural habitats.

Geographically the Vihorlat range lies in eastern Slovakia near the town of Snina and the border region with Ukraine, and it is accessible from regional roads and trailheads in the surrounding lowlands.

  • Elevation and protection: The highest point in the range reaches just over 1,070 metres, and the area is covered largely by protected forests within a designated landscape area.

What to See#

  • Morské oko lake: Morské oko is a mountain lake formed in a volcanic crater and is a notable natural attraction within the range, popular for short hikes and nature visits.
  • Summit and trails: The main summit area and surrounding beech forest feature marked trails and viewpoints that offer panoramic views of the wooded volcanic ridges.

How to Get to Vihorlat Mountains#

Nearest towns with regular bus links include Humenné and Snina. From Snina local buses and marked trails lead to trailheads in 20-60 minutes; many of the best hikes begin at small forested parking areas accessible by rural roads.

Tips for Visiting Vihorlat Mountains#
