What to See#

• Vojkova kosa: The highest point on the plateau is Vojkova kosa at 1,313 metres, which is the main destination for hikers seeking panoramic views over the Vipava Valley and toward the Adriatic coast on clear days.

The Nanos plateau in the Vipava area of Slovenia is reached by road from the surrounding towns; common access is from Razdrto/Podnanos or Predmeja. From Ljubljana it is roughly 60-80 km southwest (about a one‑hour drive) via the A1 motorway toward Postojna and then by regional roads to Razdrto/Predmeja, where parking and trailheads provide access for hiking onto the plateau. Final access onto the plateau is on foot via marked trails.

• The Nanos plateau is commonly accessed from the A1/ Razdrto area-approaching via the Razdrto pass and stopping at one of the roadside viewpoints gives the quickest panoramic views without a long hike.
• Visit early in the morning for the clearest views above the sea of fog that often fills the valleys; afternoons and low-cloud days can obscure the panorama, so check local weather and aim for a clear morning.
