Crno Jezero, or Black Lake, nestled within Durmitor National Park near Žabljak, is a highly accessible and beautiful glacial lake ideal for both solo and guided visits. Visitors can easily reach it via a short walk or drive from Žabljak, with well-maintained, relatively flat paths circling the lake suitable for most. The best time to visit is from late spring to early autumn (May-October) when the weather is mild and paths are clear; winter visits are possible but require snow gear and may have limited access. Entry to the National Park, which includes the lake, typically costs around €3-€5 per person, with a visit usually lasting 2-3 hours for a full circuit, though many spend half a day enjoying the scenery, picnicking, or swimming in summer. The lake's stunning setting, dual-lake feature (often appearing as one), and available restaurant make it a perfect spot for relaxation and photography, also serving as a gateway to further Durmitor exploration.
