Kopylash (1599 m a.s.l.) is a bold, cone-shaped summit standing on the main ridge of the Chyvchyn Mountains — part of the wider Maramureș massif. Its treeless top and steep flanks make it instantly recognizable, and the fact that the Ukrainian-Romanian state border runs right across its peak gives it a genuinely frontier feel.

The open summit means unobstructed panoramic views across the wild Chyvchyn ridges, with neighbouring Kernychnyi (1588.8 m) to the east and Reheska (1569.6 m) to the northwest visible from the top. The slopes are steep — especially on the eastern and southern sides — so expect a real workout on the way up. In summer the alpine meadows feel remote and unspoiled; in winter and early spring the steep faces can carry significant snow, making the ascent considerably more serious. The village of Zelene to the northeast is the natural gateway to this summit from the Ukrainian side.

• Village of Zelene — approach from the northeast along the main Chyvchyn ridge; difficulty: moderate to demanding due to steep slopes.

• The Ukrainian-Romanian state border crosses the summit — do not cross it without proper documentation and an official border crossing point.
• The historical 'Mackensen Road', built during World War I, passes along the northern and western slopes of the mountain and can still be partially traced on the ground.

That same Mackensen Road — a military supply route carved through the Carpathians during WWI — is one of the more fascinating traces of history you will encounter on the slopes of Kopylash, a quiet reminder that these remote mountains were once a theatre of war.
