Tucked away in the Slovak Tatras, Kolová dolina is a hidden gem that remains untouched by tourist crowds. This roughly 2.5 km side valley branching off from Zadné Meďodoly captivates with dense forest, sweeping dwarf pine slopes and the serene Kolové pleso — the largest lake in the entire Javorová dolina valley system.

The valley has a beautifully layered landscape. Dense forest fills the lower section, gradually giving way to dwarf pine scrub as you climb. At 1,565 m above sea level lies Kolové pleso, a lake of about 1.7 hectares that gives the valley its name. Higher up, a short ridge divides the upper basin into two smaller hollows. The surrounding ridgeline, stretching from Jahňací štít to Kolový štít, frames the valley with dramatic rocky peaks — especially stunning in early summer and autumn when the vegetation glows with colour.

• Trail through Zadné Meďodoly towards Kopské sedlo (Kopa Pass) — the valley is visible from this trail, offering fine views of its landscape without entering the restricted zone.

• Kolová dolina is closed to tourists — a significant part of the valley falls within a strictly protected zone of the Slovak Tatra National Park (TANAP).
• Around 30 caves have been documented in the valley, but none are accessible to visitors.

The valley has a rich human past: locals from nearby villages grazed cattle here from the 16th century, and copper and silver mines operated until the mid-19th century. In 1751, an imperial commission exploring the Tatras — including Jakob Buchholtz — visited this very valley.
