Rumanowy Staw is the kind of place that rewards only those willing to go the extra mile — literally. Tucked away at 2090 m above sea level in the Rumanová Valley, a side branch of the Zlomisková Valley in the Slovak High Tatras, this mountain tarn offers raw, untouched alpine scenery far from the tourist crowds.

Measuring 70 × 48 m and covering 0.248 ha, it is the largest lake in the Rumanová Valley — and by far the most impressive. The surrounding rocky terrain gives the place a dramatic, almost otherworldly character. In spring, snowfields reflect in the still water; in summer, the warm-coloured granite walls frame a picture of pure alpine wilderness; in autumn, early morning light turns the whole scene golden. The silence here is something you will carry with you long after leaving.

• There are no marked tourist trails leading directly to the lake. Reaching it requires off-trail navigation experience and solid knowledge of the Zlomisková Valley area and its side valleys.

• The lake lies within the Tatra National Park (TANAP) on the Slovak side — strict nature protection rules apply, including restrictions on off-trail hiking, which may require a special permit or a licensed mountain guide.
• Not suitable for inexperienced hikers due to the absence of marked routes.

The lake and the valley take their name from Ján Ruman Driečny the Younger, a celebrated Tatra mountain guide whose legacy lives on in this wild and untouched corner of the High Tatras.
