The mountain has
an inner life.
A visit to Vrelo changes the scale of a Fužine day. The lake’s open sky gives way to a close, cool interior, shaped by water and decorated with cave formations. An underground stream is part of what makes this small cave memorable.
Official visitor information describes a guided visit of about 25–30 minutes and a temperature around 8°C. The visitor path has no steps, but accessibility still deserves a direct conversation with the operator about your needs. Heavy rain and high water can affect visits.
